1 Prof. Oral Buyukozturk Massachusetts Institute of Technology Outline /1.541 Mechanics and Design of Concrete Structures (3-0-9) Outline 1 Introduction / Design Criteria for Reinforced Concrete Structures Structural design o Definition of design: Determination of the general shape and all specific dimensions of a particular structure so that it will perform the function for which it is created and will safely withstand the influences which will act on it throughout its useful life. Principles of mechanics, structural analysis, behavioral knowledge in structures and materials. Engineering experience and intuition. (a) Function, (b) strength with safety requirements will vary for structures. Influences and structural response: Influences Structure Structural response Loads Temperature fluctuations Foundation settlements Time effects Corrosion Earthquakes Other environmental effects Failure (strength) Failure mode Deformations Cracking Stresses Motion o Structural mechanics: A tool that permits one to predict the response (with a required level of accuracy, and a good degree of certainty) of a structure to defined influences. 1 / 7

2 o Role of the designer (engineer) of a structure Design criteria for concrete o Two schools of thoughts 1. Base strength predictions on nonlinear theory using actual σ- ε relation 1897 M.R. von Thullie (flexural theory) 1899 W. Ritter (parabolic stress distribution theory] 2. Straight-line theory (elastic) 1900 E. Coignet and N. de Tedesco (the straight-line (elastic) theory of concrete behavior) o Working Stress Design (WSD) Elastic theory 1. Assess loads (service loads) (Building Code Requirements) 2. Use linear elastic analysis techniques to obtain the resulting internal forces (load effects): bending, axial force, shear, torsion At service loads: σ max σ all c ' e.g. σ all = 0.45 f c compression in bending s σ all = 0.50 f y flexure o Ultimate Strength Design (USD) The members are designed taking inelastic strain into account to reach ultimate strength when an ultimate load is applied to the structure. The load effects at the ultimate load may be found by (a) assuming a linear-elastic behavior (b) taking into account the nonlinear redistribution of actions. Sectional design is based on ultimate load conditions. Some reasons for the trend towards USD are (a) Efficient distribution of stresses 2 / 7

3 (b) Allows a more rational selection of the load factors (c) Allows designer to assess the ductility of the structure in the post-elastic range o Limit State Design Serviceability limit state: Deformation, fatigue, ductility. Ultimate limit state: Strength, plastic collapse, brittle fracture, instability, etc. It has been recognized that the design approach for reinforced concrete (RC) ideally should combine the best features of ultimate strength and working stress designs: (a) strength at ultimate load (b) deflections at service load (c) crack widths at service load o ACI (American Concrete Institute) Code emphasizes: (a) strength provisions (b) serviceability provisions (deflections, crack widths) (c) ductility provisions (stress redistribution, ductile failure) Design factors o 1956 A.L.L. Baker (simplified method of safety factor determination) o 1971 ACI Code (load factors and capacity (strength, resistance) reduction factors) o 2002 ACI 318 Building Code o Design loads (U) are factored to ensure the safety and reliability of structural performance. o Structural capacities (φ) of concrete material are reduced to account for inaccuracies in construction and variations in properties. 3 / 7
