Article 4.3.6.2 Account * IMPORTANT EXPLANATION *

[Ismail Hakki Besler]

In rigid basement-floor structures, design your project by following the steps below, using the one-stage calculation as per Article 4.3.6.2 only as a preliminary design. Whatever the carrier system of your building is, optimize the project in the following order 1. According to step 4.3.6.2 Single stage calculation and rigid diaphragm solution At this stage, have the rules that are not provided according to the earthquake code given to you by the program. Don't optimize for the basement. Don't optimize for the foundation. 2nd Stage Two-stage calculation and rigid diaphragm solution according to Articles 4.8.5.1, 4.8.5.2, 4.8.5.3 At this stage, make the optimizations about the basement floors. Also do basic optimizations. 3. According to step 4.3.6.2 Single stage calculation and semi-rigid diaphragm solution At this stage, make the optimizations for floors and beams on the upper floors. 4th Stage Two-stage calculation and semi-rigid diaphragm solution according to Articles 4.8.5.1, 4.8.5.2, 4.8.5.3 At this stage, make the optimizations for the basement floors and basement beams. As you know, as of ideCAD Static v10.17, a calculation method has been added to the program according to Earthquake regulation Article 4.3.6.2. This method is a method that allows faster calculation. However, it is a method that, in terms of its results, causes larger cross-sectional effects in basements than the two-stage calculation. It is a method that is much more sensitive than the existing and other method and recommended by the regulation. On the upper floors, there is no difference between the two methods. But there are serious differences in the basement floors. For this reason According to Article 4.3.6.2, one-stage calculation is used only as a preliminary design and in the last step, two-stage calculation is Article 4.8.5.1 , 4.8.5.2 , 4.8.5.3 We recommend that you use
