The reinforced concrete structure, which you can see in the above plan and 3d view, consists of 3 openings, 2 6 m and 10 m, in the X direction, while it has 2 4 m openings in the Y direction. The structure modeled as a reinforced concrete moment-transmitting frame and semi-rigid diaphragm will be solved by dynamic (modal) analysis in accordance with the dynamic additional eccentricity method and earthquake effects will be determined by mode coupling method. Below is a comparative model and outcome review with ETABS.
Soil parameters for latitude longitude and TBDY 2018 of the building, elastic spectrum values and BYS, BKS, DTS etc. The classification is shown in the image below. C30 S420 material is used for frame elements and C20 S420 material is used for flooring.
Project data: Solutions were made with ETABS v17 and ideCAD Statik v10.91.

The calculation made in the relative floor drift section of the ideCAD Static Earthquake regulation report is below.
g) Second Order Effect Calculation
İkinci Mertebe Etkileri section is the philosophy of the account and how it is done. This account cannot be obtained directly from ETABS. The necessary data is taken from ETABS and calculations are made manually.
Calculation results are given in the second-order effects section of the ideCAD Static Earthquake regulation report.
