2 Problem Description and Research Approach of Proposed Work for Year 8: (Detailed description of research to be conducted and methodology to be used.) S. Chang " Direct Losses, Social Impacts, and Community Resilience: L.A. Lifeline Study (networking sub-task) (Subtask of Thrust Area 1 and 3) This is a networking sub-task for the TASK Direct Losses, Social Impacts, and Community Resilience: L.A. Lifeline Study (submitted separately) which describes the development of a computational tool for lifelines-related loss and community resilience, which will be made available to the Users Network of MCEER. The work in this subtask will create a website that will allow users to access the L.A. loss model software, supporting documentation, and database of preliminary results. In addition, the website with the Memphis loss model and databases, developed in previous years, will be moved from the University of Washington to the University of British Columbia. The L.A. loss model is new. While deriving from the Memphis loss model, it incorporates a number of major modifications and refinements (described in the main task see progress to date ). This is a continuation task from previous years and is intended to complete prior commitments. In MCEER's new systems approach, the quantitative measurement of resilience is a central area of new research. This project aims to develop a loss model and related measures of community resilience for the Los Angeles lifeline study. The objective in Year 6 is to transfer the Memphis lifeline loss model framework to L.A. and expand it in the direction of social losses. In Year 8, I propose to refine the L.A. loss model in three ways: (1) Performance objectives, which are needed to quantify resiliency, will be revised. This will be accomplished through consultation with lifeline management practitioners, as well as other MCEER researchers. (2) The social resiliency dimension of the model will be expanded to include outages to hospitals. This will entail collecting data on the L.A. regional hospital system. (3) Preliminary testing of the model will be conducted. Results from MCEER s engineering models of water and power damage, outage, and restoration in L.A. will be incorporated to the extent that they are available. If unavailable, dummy data will be used in the interim. This networking subtask is associated with a main task in which a loss model and related measures of community resilience are being developed for MCEER's Los Angeles lifeline study. The networking products to be prepared in Year 8 include a software tool and example for evaluating social and economic measures of resilience. In the networking subtask for the L.A. lifeline study, it is proposed to prepare some web-based computational databases. These databases will include the results of the preliminary testing of the L.A. loss model. The results will pertain to resiliency outcomes (technical, organizational, social, and economic) for various testing scenarios. The loss and resiliency software would be designed to facilitate future integration with engineering models that other MCEER researchers are currently developing for water and electric power damage, outage, and restoration. The example would pertain to a testing scenario. Association documentation will be developed. Project Schedule and Milestones: (Milestones and estimated time of achievement; e.g. Fall, Spring, Summer.) Winter 2005: Design website, gather content, investigate security options. Spring 2005: Migrate Memphis website to UBC. Autumn 2005: Post L.A. loss model and related documentation and databases. Winter 2005: Develop supplementary documentation as needed. Complete website.

3 R. Eguchi: Satellite Imagery Database & MCEER Virtual Reconnaissance System (VRS) (Subtask of Thrust Area 3) This task explores the feasibility of creating an on-line map catalog of aerial and satellite images from recent disasters. This will provide a template for serving imagery, GIS data, GPS data, digital photos and digital video in near real time for future events. As part of this task, we will approach various satellite companies and agencies to discuss possible Memorandum of Understandings (MOU) with MCEER. This supplemental task is associated with our main task on Use of Remote Sensing for Emergency Response and Recovery. To date, there is no efficient way for MCEER investigators to share and transfer large remote sensing files. Typically, these files are on the order of several hundred megabytes, thus making it unreasonable or impossible to transfer data by conventional methods such as attaching the file to an message. Disseminating the results of advanced technology research has been problematic because of the difficulty in transferring and viewing files. In order to market MCEER s remote sensing research program, it will be necessary to develop and maintain a map interface on the MCEER website where imagery and analysis can be viewed or retrieved perhaps for a publication fee. The following approach is proposed: 1. Identify current images in MCEER s project file 2. Work with MCEER s information systems manager to develop a protocol to assess images on MCEER s website. 3. Begin effort to develop MOUs with satellite data providers, e.g., USGS, Digital Globe, Space Imaging, European Space Agency, SPOT, Intermap, and others 4. Create a mechanism where MCEER investigators can transfer and share large datafiles. Of specific interest are efficient data compression algorithms that will allow the rapid sizing and re-screening of images while on-line Work with other Program 3 investigators to identify information transfer needs, particularly with respect to post-event decision support systems. Project Schedule and Milestones: (Milestones and estimated time of achievement; e.g. Fall, Spring, Summer.) 1) Finalize PC version of VRS program, known as "VIEWS" to collect data to serve on the website (spring 2005) 2) Deploy MCEER website for visualizing remote sensing images and multimodal data (summer 2005) M. Grigoriu, " Fragility Based and Rehabilitation Decision Analysis (Subtask of Thrust Area 2 (and 1) This is networking sub-task for the TASK (submitted separately) which describes the development of a computational tool that will be made available to the Users Network of MCEER. The main objective of the task Fragility Based and Rehabilitation Decision Analysis is the development of a methodology for the seismic evaluation and rehabilitation for structural and non-structural systems in health care facilities. The essential goals of the networking subtask are the following: (1) A computer code is currently under development to evaluate different rehabilitation alternatives for simple systems under Gaussian ground motion excitation. This code will be

4 made available to the Users Network of MCEER by May In year 8 this code will be extended to account for non-linear non-structural systems subjected to Gaussian and non- Gaussian seismic ground motions. A manual will be created to guide the users and to show some example applications. (2) An extensive computational database for fragility information will be developed and validated for selected non-structural components. The database will be made available to Users Networks (3) Lifecycle costs, recovery times and available infrastructure operation capacities will be placed on the Users Networks and presented for a demonstration hospital for alternative rehabilitation strategies. This document will be obtained by using the computational tool that is described above. The document will be made available to the Users Network of MCEER. Spring 04: Demonstration of the methodology and the computational tool for rehabilitation decision analysis using a simplified structural/non-structural model. Completion of the computer code to generate samples of seismic ground acceleration records at single and multiple sites using Gaussian models. Summer 04: Improvement of the computer code for generating samples of ground accelerations records by including non-gaussian models. Fall 04: Preliminary extension of the computational tool for rehabilitation decision analysis to arbitrary structural and non-structural systems for Gaussian ground accelerations A.S.Whittaker: Software and database of integrated evaluation of nonstructural and structural response data (SubTask of Thrust Area 2) This is the networking subtask for the primary task Emergency Care Facility Evaluation through Integration of Nonstructural and Structural Response Data that describes the development of a computational tool or database, which will be made available to the Users Network of MCEER. The scope of this subtask is to continue development, publication, and distribution of a database and the associated knowledge tools for use by the Users Network of MCEER. The database will include (a) mathematical models of MCEER-studied emergency care facilities, including models of the three demonstration hospitals for use with one or more computational platforms [SAP, IDARC, OpenSees], (b) results of the analysis of the models by MCEER researchers, (c) fragility data for non-structural components that are commonly found in hospitals, and (d) Matlab files for the generation of fragility curves for user-defined inputs. Sample results will be presented to the Users Network with a Users Guide. The database of information and knowledge related to emergency-care-facilities and mathematical models (on a variety of platforms) will be established in close consultation with Professor Reinhorn to maximize the benefit of the work conducted by individual MCEER investigators and to best serve the stated need for program integration. The database and its evaluation tools will be developed, published, and distributed through the MCEER Users Network. Project Schedule and Expected Milestones for the Project: Refer to the main task statement submitted under separate cover. G. Dargush, Software for Evolutionary Methodologies for Decision Support (Subtask of Thrust Area 2) Over the past several years, MCEER has supported the development of an evolutionary optimization approach for the aseismic design and retrofit of passively damped structural

5 systems. This approach has proved to be quite promising and the reliability of the associated software has continued to improve. An initial beta version of the software is now ready for incorporation into the MCEER Networking Facility for use within the MCEER community of researchers and industry partners. We expect to have this in-place by March This initial release of the code Evolutionary Aseismic Design and Retrofit (eadr_1.0) includes the capability to optimize the type, size and location of passive damping elements in a structure subjected to an uncertain seismic environment. Available damper types include metallic, viscous and viscoelastic devices. The seismic environment utilizes far-field and near-field synthetic ground motions based upon the Papageorgiou model for Eastern North America. The structural system idealization for eadr_1.0 is limited to lumped parameter models with the nonlinear transient dynamic analysis performed using an explicit state-space formulation. Options provide for the specification of the design space of possible structures, drift and acceleration limits, and cost/benefit functions. Afterwards, we will direct our effort toward the release of an extended parallel version of the code (eadr_2.0) with an enhanced seismic environment model and an improved user interface. We plan to release this extended version in Fall For the remainder of our Year 8 Networking effort, we will concentrate on developing software for the organizational modeling of acute care facilities. We expect to provide MCEER researchers and partners with an initial version of this software by the end of Summer The continuation of this plan would then focus our Year 9 Networking activities on the release of an initial version of the overall evolutionary decision support software, incorporating both the organizational modeling approaches and the structural optimization methodologies. 1. We will direct our effort toward the release of an extended parallel version of the Evolutionary Design and Retrofit code (eadr_2.0) with an enhanced seismic environment model and an improved user interface in Fall For the remainder of our Year 8 Networking effort, we will concentrate on developing software for the organizational modeling of acute care providers. 3. We expect to provide MCEER researchers and partners with an initial version of this software by the end of Summer G.C. Lee Database for Seismic Evaluation of NY State Hospital (Subtask of Thrust Area 2) This is networking sub-task for the TASK: Seismic Evaluation of New York State Hospitals (submitted separately). In this subtask, a web-based database of NY State Hospital facility system is to be constructed for the Users Network of MCEER. The database is intended to include structural, architectural and other non-structural systems (power, water, HVAC, med gas and Fire protection). For some hospitals, stand along medical equipment will be collected for seismic protection analysis. The work in this subtask will create several real hospital examples for the researchers in thrust 2 to examine and compare the similarity or differences between East coast and West coast hospitals. To date a database has been built with four hospitals from New York State. In 2003, the fourth hospital database has been formed. This example is different from the other three in that it has been focused on the non-structural components. The database examples include: FEM (finite element model), drawings, and non-structural systems (power, water, fire protection, partial HVAC and med gas). The database which will be released to the Users Network is to be developed with a graphic-oriented user interface such that query of

6 information will display relative geometric, physical and logical relation with other components. Refer to main task. Tom O Rourke; Database on Integrated Water Supply and Building Information Using GIS (Task Completion), (Subtask of Thrust Area 1) The work in this subtask will continue the work in Year 7 that concentrates on creating a GIS database for water supply lifelines in the Los Angeles area, including repair locations, repair statistics, and strong motion data for the Northridge earthquake. The work in Year 8 will finish the lifelines GIS and will focus on timber frame structures. Geocoded data on damage expressed as a percentage of replacement cost, existing structures in January 1994, and ratio of damaged structures to number of existing structures will be developed. The database includes state of repair statistics on over 50,000 structures and tax accessor records for over 270,000 buildings in the San Fernando area. Currently, networking development for Year 7 at Cornell is including development of a GIS database with the records of more than 1000 pipeline repairs, approximate locations of water trunk and distribution lines, complete strong motion records at 164 places, and data pertaining to permanent ground deformation, surficial soils, groundwater tables, topography, and street system. The database, which is of unprecedented size and complexity, will be made available to selected users through Users Network of MCEER. Refer to main task. M. Shinozuka, Integrated evaluation of system performance Transportation software (Subtask Thrust Area 1 and FHWA Transportation.) This is a networking sub-task for the TASK Advanced Technologies for Loss Estimation and Development of Damage Function Using Remote Sensing and Real-Time Decision Support Systems. The work in this subtask will create an initial code Lifeline in a format that can be shared by the Users Network of MCEER. This subtask will create a numerical analysis tool that can be used for the pre-event emergency response planning and also for post-event real-time decision making in relation to emergency response. Use of remote-sensing capability will be integrated in the initial Lifeline T. Year 8 will also see the initiation of development of software package of power systems. The impact of severe earthquakes on transportation network systems physically and operationally is damaging and complex. Studies on transmission network systems are being performed by researchers specialized in transportation engineering and science. In particular, three NSF s Earthquake Engineering Centers, MCEER, PEER, and MAE are engaged in the study as it pertains to the seismic performance of transportation networks. PEER concentrates on Bay Area networks by simulation and MAE focuses on a large network of national scale. The research here is to develop an optimal set of computational modules evaluating site ground motion, fragility, network damage, (in terms of appropriate measures including driver s delay), direct and indirect economic losses and social impact. The ultimate goal is to provide a useful set of decision support systems in technical, economical, social, and organizational dimension. In this respect, this is a unique effort no other researchers are currently engaged in. In Year 6, while pursuing an MCEER/FHWA research project on fragility curves for retrofitted bridges by means of steel jacketing the columns, a method was developed to characterize and

7 quantify the effect of seismic retrofit. This method will play an important role in evaluating the effect of retrofit on highway networks not only technically, but also socio-economic dimensions. The method will be integrated into the software as a critical module. In addition, Year 7 effort produced two modules which are being integrated into the global analysis tool. One is a module in which statistical uncertainty of fragility curves and the other is a module for a dynamic collapse prediction tool UCI developed. In line with the major theme of emergency response, development of a decision support system was initiated also in Year 7 which helps emergency managers to execute optional transportation of the injured to available hospitals. Refer to main task. Emanuel Maragakis Implementation of Database for Experiments on Fragility of Nonstructural Hospital Piping Systems (Thrust Area 2 and Networking Program) The objective of this sub-task will be to make use of the recently developed networking infrastructure to disseminate experimental data from non-structural piping experiments conducted at the University of Nevada, Reno. Due to the wealth of data available, such dissemination will serve as a showcase example of the use of the recently developed networking infrastructure implementation. The objective of this subtask is to build a benchmark example based on previous steps taken towards the development of a large-scale network system for the purpose of networking of MCEER experimental and computational facilities through the Internet. This network system will allow researchers and engineers to share the up-to-date information about the laboratory experimental facilities, as well as, the research activities and achievements performed by different institutions. Steps have been taken already in year 7 toward the accomplishments of networking of the facilities. It is necessary, however, to complete, test, and implement the available networking tools. In year 8 the goal of this task is to set an example to show the usefulness of the developed protocol in disseminating data to allow a better interaction and information exchange among the experimental and computational facilities and laboratories of the participating institutions in MCEER as well as laboratories of other institutions from around the country or the world through the Internet. The approach will include the dissemination of experimental data of a series of experiments on non-structural hospital piping systems conducted at the University of Nevada, Reno. Task 1: (Fall 2004) Organizing the data and the meta-data from the non-structural piping experiment.; Starting the implementation phase Task 2: (Spring 2005) Publishing data related to welded pipe systems; Publishing data related to threaded pipe systems Task 3: (Summer 2005) Finalizing and testing the template; Uploading the template to BRIC website Task 4: (Throughout the year) Continuing the efforts of updating, implementing and maintaining the currently available experimental networking services. This includes updating the information about the experimental laboratory facilities and capabilities at UNR, the detailed list of lab equipment and their specifications, the most recent publications containing information about findings and achievements of experimental research activities performed at UNR, the experimental protocols and others.
