Turkish Hello, I will do an earthquake performance analysis of a 3-storey school building with a ZB floor, and in the strengthening section, do I need to tick the two options that I have marked, which are load combination options as in the photo, can you inform me about this? I know that normally we need to use vertical earthquake effect, do I need to use it in this case and do I need to tick the secondary earthquake box too, thanks

Vertical earthquake effect while performing earthquake performance analysis

Hello there; Linear performance analysis is performed according to the rules described in TBDY Chapter 15. However, there is no clear statement in this section that 0.3 times the vertical earthquake effect or the effect in the direction of the secondary earthquake should be taken. Conditions in Chapter 5 are applied for new buildings. In TBDY Article 5.2.2.1, it is stated that while horizontal seismic effect is taken, Ex+0.3Ey effect and vertical seismic effect should definitely be taken into account in buildings with SGDT approach according to Chapter 5. Although linear performance analysis is a linear method, it is evaluated with the SGDT approach. Because the plastic rotation of the elements and the unit deformation results are examined. These results are computed with a linear approach only, but the method itself is the evaluation and design approach according to Shapeshift. Therefore, ticking these boxes, that is, considering the secondary earthquake direction and the vertical earthquake effect, is more appropriate than Chapter 5 and the SGDT approach. Best regards...
