In accordance with the article 4.3.4.4 of TBDY 2018, all earthquake effects in structural systems with beamless floors should be covered by porous walls with high ductility level and / or walls with high ductility level or limited voids. The model of the building was created in accordance with this condition.
In accordance with the same article, two-stage calculations must be made in carrier systems that contain no beams.
In the first stage calculation, the frame columns are hinged from the bottom and from the top.
In the second stage calculation, frame columns are modeled monolithic.
Curtains, columns, crosses and floors are designed in accordance with the unfavorable internal force results obtained from these two stages.
The relative storey drift is calculated in accordance with the second stage calculation results.
Analysis results for both loading conditions can be examined on the program interface and detailed reports can be obtained.
The building requires 2 different 2-stage calculations because it includes both a non-beam floor and a basement. The results of these calculationsSpecial Analysis Rules in Basement Structures as per TBDY 2018 is detailed in theSpecial Analysis Rules in Basement Structures as per TBDY 2018 section forSpecial Analysis Rules in Basement Structures as per TBDY 2018.
