The reinforced concrete structure, which you can see in the above plan and 3d view, consists of 3 axis, 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 frame and semi-rigid diaphragm is solved by dynamic (modal) analysis in accordance with the dynamic accidental torsion method and earthquake effects will be determined by modal combining method. Below is a comparative model and outcome review with ETABS.

Soil parameters for latitude and longitude TBDY 2018 of the building, elastic spectrum values ​​and Risk category, SDC etc. The classification is shown in the image below. C30 S420 material is used for frame elements and C20 S420 material is used for floor.

Project data: Solutions were made with ETABS v17 and ideCAD Statik v10.91.

e) Calculation of the Amplification Factor according to the Equivalent Seismic Load Method

Equivalent Lateral Force Method 12.8.1.1 Seismic Response Coefficient for Equivalent Lateral Force Method

The information used in the calculation in the ideCAD Structural Dynamic analysis report is summarized below.

f) Relative Story Drift Calculation

12.12 Determination and Limitation of Story Drifts

The calculation made in the relative story drift section of the ideCAD Structural Seismic regulation report is below.

g) Second Order Effect Calculation

12.8.7 P-Delta Effects 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.
