1 LIST OF CHANGES 1 (17) CHANGES IN SOFTWARE VERSION FINNWOOD 2.3 SR1 (RIL ) Finnwood version 2.3 SR1 (RIL ) includes the following changes compared to the previous version Finnwood 2.3 (RIL ). The changes have been categorized as follows: User interface, Design principles, Printouts and Other changes 1. USER INTERFACE 1.1. The software version number is 2.3 SR The user interface includes the new Metsä Wood logo All references to Metsäliitto Cooperative, Finnforest have been removed. The company name is now Metsä Wood.

2 LIST OF CHANGES 2 (17) 1.4. The validity of the Finnwood password is now visible at the bottom of the window and in the About Finnwood window A new Welcome tab has been added to the program. The default view on this page is the brochure of that can also be viewed by clicking on the left hand button Brochure. The Welcome tab also includes buttons for the following features: - Viewing the Help document (available only in Finnish) - A link to the Finnish webpage of Metsä Wood - A link to the webpage of the Finnwood program The design calculation templates included in the software version 2.3 have been amended as follows: - All default wind loads on roof structures have been decreased so that the new loads are 0,6 kn/m 2 in spans and 1,2 kn/m 2 on the cantilevers. - The material of the roof rafter templates has been changed to the new Kerto-QP roof beam and the dimensions of the structures have been changed to suit the new material. - A new template has been added for the free structures: a main column with hinges at supports and wind load acting up and down The program includes the following new or updated products: - Kerto-QP (as beam or plate) - Glulam strength classes GL30c and GL30h - Metsä Wood glued posts has replaced the product name FF (Finnforest) glued posts

3 LIST OF CHANGES 3 (17) - Metsä Wood Spruce plywood (parallel or perpendicular) has replaced the product name Finnforest Spruce plywood (parallel or perpendicular) The new product selection has been updated to the Finnwood licence agreement In the database window of rectangular cross-sections, changing the active database/material opens a new Choose active database window. In this window the selection of the material is done from a drop down menu that is identical to the material list shown on the Design page The database of structural saw timber (strength classes C14, C18, C24, C30, C35 and C40) has been complemented with double cross-sections The database windows of Kerto-Ripa elements have been improved as follows: - The new Info page includes guidelines for choosing the cross-section parameters of Kerto-Ripa elements.

4 LIST OF CHANGES 4 (17) - It is possible to view the picture of the active slab in scale or its input parameters. - The restrictions of the parameters of the database window have been updated as follows: The height of the ribs should in all slabs fulfil the restriction H1 = mm and H2 = mm. The width of the top plate has to fulfil the condition B 2520 mm. The minimum amount of ribs of a 2.5 meter-wide element is three. For the Kerto-Q top and bottom plates the maximum width of the free edge of the flange is 20h f, where h f is the sanded thickness of the Kerto-Q plate (e.g. 25 mm).

5 LIST OF CHANGES 5 (17) In the database windows this geometrical restriction concerns the parameters B11, B12, B21 and B22 for ribbed and box slabs and B11 and B12 for open box slabs. For the Kerto-S bottom plates the maximum width of the free edge of the flange is 10h f, where h f is the sanded thickness of the Kerto-S plate (e.g. 44 mm). For open box slabs this geometrical restriction concerns the parameters B21 and B22. - With Kerto-Ripa box slabs, Wooden panel, no composite action is a possible top plate material in addition to Kerto-Q plates. This option has been given low values of strength and modulus of elasticity so that it cannot be in composite action with the ribs of the Kerto- Ripa element. The volume weight of the material is, however, taken into consideration in the calculations as 5,0 kn/m 3. The Finnwood user should also make sure that the chosen wooden panel with no composite action fulfils the requirements for local resistances (bending, shearing and deflection) All pictures of the structure and all holes and side supports added to the structure are presented in scale.

6 LIST OF CHANGES 6 (17) The size of the Loads and load combinations window that opens from the Loading page can be adjusted The layout of the Design page has been updated and it now includes new features. - The content of the page has been divided into three sections: PROFILE SELECTION, DESIGN PARAMETERS and DESIGN RESULTS.

7 LIST OF CHANGES 7 (17) - The spacing of the structural member or the loading width can be changed in the drop down menu located next to the list of cross-section sizes. - The structural information of rectangular cross-sections now includes the area A, the bending stiffness I y and the section modulus W y. This information is also shown on the Printouts page.

8 LIST OF CHANGES 8 (17) - The drop down menus for service class and reliability class are presented without separate titles. - A new header line STRUCTURAL DESIGN has been added for the design settings. The buttons for opening the calculation setting windows have also been updated. NOTE! The button for STRUCTURAL DESIGN opens the window for general calculation settings. - The note for checking the design settings has been updated. Additional instructions are presented for Kerto-Ripa elements that are used for base floor or intermediate floor structures.

9 LIST OF CHANGES 9 (17) - The total utilization rate, the coordinate system and the buttons for viewing the design results (i, + and -) are now located under the heading DESIGN RESULTS. - The Help tab of all design setting windows has been renamed as Info tab. - The volume weight [kn/m 3 ] of the structure is presented after the material values on the DESIGN and Printouts pages New side support options Side supports can be applied to a structure (e.g. a sloped roof beam) when it is converted to a free structure. There are two new options for side supports: Above and below (the member) and Between members.

10 LIST OF CHANGES 10 (17) The Finnwood Help document (in Finnish) has been updated as follows: - The new features of the software version 2.3 SR1 have been explained in the document. - The new materials and their material values have been presented in the document. - The pictures and instructions included in the document have been updated to correspond to the changes made in the user interface of. - The instructions presented for the bending, shear and deflection calculation of the upper plates of Kerto-Ripa elements have been updated. - New information has been added to explain the content of the printouts and printout files. 2. DESIGN PRINCIPLES 2.1. Design calculations saved with Finnwood 2.3 are compatible with the new version Finnwood 2.3 SR1. If the material used in the design calculation of the previous version no longer exists in version 2.3 SR1, the designing of the structure has to be performed again on the DESIGN page The material values of Kerto-QP products are according to the VTT Statement VTT-S The material values of the glulam strength classes GL30h and GL30c are according to the VTT Research Report VTT-S The design calculations and material values of Metsä Wood glued posts are according to the VTT Research Report VTT-S The shear strength of structural saw timber is according to the standard EN 338: The design calculations of Kerto-Ripa elements have been updated according to the Kerto- Ripa Design Instructions approved on June 20 th, These changes concern the shear

11 LIST OF CHANGES 11 (17) resistance of the glue line and the effective width of the flanges. However, the changes do not apply to the bottom flanges of the open box slabs that are made of Kerto-S The default wind loads of the Wizard of basic model window of roof structures have been changed to the following: 0,60 kn/m 2 in spans and 1,2 kn/m 2 on the cantilevers. The default settings of this window can be viewed by selecting File > New calculation and Cancel in the window that opens The calculation setting window for buckling checking has got a new Info page with the following content.

12 LIST OF CHANGES 12 (17) 2.9. Changes in the calculation of lateral torsional buckling The titles of the lateral torsional buckling window concerning the side supports above and below the member have been updated. The terms (with My>0) and (with My<0) have been added to clarify the application of supports. In the calculation setting window of the lateral torsional buckling checking, the parameter Location of the loading shown for rectangular cross-sections has been changed to Effective torsional buckling length. The selecting of the parameter is still done with a drop down menu, but the content of the menu has been updated. The default setting is presented below. The change is due to the additions presented for the Design Instructions of RIL on September 23 rd, The full updated selection list is as follows: These changes have also been made to the corresponding Info page The calculation setting window of deflection checking has been updated as follows: The text of the precamber field has been updated so that the precamber is defined as the absolute precamber Wc and the precamber is located at mid-span.

13 LIST OF CHANGES 13 (17) It has been noted in the instruction text of precamber that it is normally possible with glulam members. Figure 7.1 of the EC 5 standard has been added to the window to make the selection of deflection parameters easier Changes in the calculation of vibration checking The Info text has been clarified as follows: Version 2.3: Version 2.3 SR1:

14 LIST OF CHANGES 14 (17) The mass m used in the vibration checking is now calculated as the sum of the self-weight of the floor and the permanent part of the imposed load (30 kg/m 2 ) as presented in the additions of RIL presented on January 30 th, The instructions of the Info page of the vibration settings window have been updated accordingly. The above-mentioned means that in the calculation of the mass m it is not possible to use the factor α A anymore. The possibility of using the factor in the vibration checking ended as the additions of the national annex of EN :2002/AC:2009 came to effect on January 1 st, In the vibration settings window, the selections for a floating structure have been changed so that the word gypsum plate has been replaced by floor gypsum plate, e.g. 47x98 c/c x15 mm floor gypsum plate. The same changes have been made to the Info page. The selection list for Floor plate above beam is now called Floor plate/structure above beam. This list also includes a new addition: Tongue-and-groove planking 28x95 C18. These changes have been made to the Info page, too The usage of Kerto-Ripa elements as columns is prevented by excluding them from the drop down menu Shape of cross-section on the DESIGN page. If any other column member is converted to a free structure, Kerto-Ripa elements appear in the Shape of cross-section list. Since the calculation of Kerto-Ripa elements as columns is not sufficiently defined, the following note (in red) is shown to the user on the DESIGN page of the free structure: NOTE! Kerto-Ripa elements shall not be used as column or wall structures due to inadequate design calculations. The stability of vertically oriented Kerto-Ripa elements is not checked.

15 LIST OF CHANGES 15 (17) The Info tab of the general calculation settings window has been clarified for Kerto-Ripa elements as follows: Version 2.3: Version 2.3 SR1: 3. PRINTOUTS 3.1. The heading Structural design has been added to the PRINTOUTS page A new note regarding snow loads has been added to the PRINTOUTS page: - Loading information presents the characteristic value of the snow load on the roof. This value is obtained by multiplying the characteristic snow load on the ground by the form factor The information about the components of a Kerto-Ripa element shown on the PRINTOUTS page has been re-arranged. The new order is: size, volume, material. The columns of the printout stay in order now even when the option Wooden panel, no composite action is chosen as the top slab of a Kerto-Ripa box slab. Version 2.3

16 LIST OF CHANGES 16 (17) Version 2.3 SR The information about precamber on the PRINTOUTS page under the heading DESIGN PARAMETERS has been updated as follows: - The precamber of a member was previously presented on the PRINTOUTS page without a unit. The unit [mm] has now been added. - When a calculation includes precamber, the designer/engineer is asked to make sure that the chosen material can have precamber. Precamber: mm NOTE! Structural designer/engineer shall ensure that the chosen material can have precamber 3.5. When a hinge is added to a structure (possible only with a free structure) the shear resistance at the point of the hinge is show on the DESIGN and PRINTOUTS pages under the headings ADDITIONAL CHECKINGS and ADDITIONAL DESIGN RESULTS. These calculation results are always shown in the printout. The results can be hidden by unchecking the box Holes/Hinges Support reactions of side supports When a structure is under lateral loading and the structure has side supports between the members, the loads received by the side supports are shown on the PRINTOUTS page. Example: Supports 4 and 5 act as side supports for the lateral wind load.

17 LIST OF CHANGES 17 (17) 3.7. The company name on the Copyright text of the PDF printouts has been updated to Metsäliitto Osuuskunta, Metsä Wood. The year of the copyright is now OTHER CHANGES VTT has performed a third party checking for (VTT-S ).
