The reinforced concrete structure, which you can see in the above plan and 3d view, consists of 3 openingsaxis, 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 is solved by dynamic (modal) analysis in accordance with the dynamic additional eccentricity accidental torsion method and earthquake effects will be determined by mode coupling modal combining method. Below is a comparative model and outcome review with ETABS.
Soil parameters for latitude and longitude and TBDY 2018 of the building, elastic spectrum values and BYS, BKS, DTS 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 flooringfloor.
