B. COLUMN REINFORCEMENT DETAILS

46 CHAPTER B: COLUMN REINFORCEMENT DETAILS Remember, after you have finished, go to the Connectors field and make modifications to update both the project and the issue. EUROCODE 8-1 IMPORTANT REMARKS: Regarding the calculation of the wall edge restraint fasteners at their critical height, based on EC8-1. For the initial dimensioning of the wall, the following applies: 1. It is mandatory to check for tightening at its critical length except in the case where νd is less than 0.15 (for DCM only) and except in the case where νd is less than 0.15 (for DCM only). case the result is negative. 2. The number of connector segments considered by the program in the initial shear and tension test is always n = 2 (worst case). status) for both addresses. It is not possible at this stage to take into account the actual segments per direction. This can be done in the recheck. 3. A key change from the calculation of νd in ECOS and EC8-1, is that in ECOS the νd is calculated and relates to the column (axial reduced to the column and area of the column) whereas in EC8-1 the νd is calculated with the whole axial and the whole cross-section. This also applies to the control reduced CT. Note that with "whole" axonal and area sizes the results are generally more favourable. In the exploration and at the end of the file, the sizes calculated are detailed. In the above text, 200 cm is the total dimension of the wall. Then the axial N which is the total, Ac=2x0.4=0.8 m2 (the total cross-section for the calculation of νd), νd which as we said refers to the whole cross-section and the sizes Ao, bo0, bo1, Σbi which refer to the column. The quantities ρv and ωv refer to the mechanical percentage of vertical truss reinforcement. Wwdreq is the size required by equation 5.20 of EC8, while Wwcalc is the realisable and corresponds to F8/10 (dimensional) and the corresponding volume of the column based on the following formula Wwdcalc As far as the size Vs for the connectors is concerned, the program, always in the initial dimensioning and always for the walls, takes into account the direction perpendicular to the small side of the wall. This is to compensate for the unfavourable effect of the two-part connector, which is taken into account in both directions, whereas in at least one direction a connector with more than two parts is normally obtained. Finally, I emphasize that the segments and Vs only concern Wwdcalc.
