In accordance with the article TBDY 2018 4.3.4.4 of TBDY 2018, all earthquake effects in structural systems with beamless floors flat slabs should be covered by porous walls with high ductility level and / or walls with high ductility level or limited voidsspecial shearwalls and shearwalls with coupling beams. The model of the building was is created in accordance with this condition.
In accordance with the same article, two-stage calculations must be made done in carrier systems that contain no beamsflat slabs structural systems.
In the first stage calculation, the frame reinforced columns are hinged from the bottom and from the top.
In the second stage calculation, frame reinforced columns are modeled monolithic.
CurtainsShearwalls, columns, crosses braces and floors slabs 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 flat slab and 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.
