As stated in TBDY 2018 4.5.1.1 and 4.5.1.2 conditions, the mathematical model of the building was created in three dimensions. The earthquake effect in two horizontal directions perpendicular to each other is taken into account.
Based on the TBDY 2018 4.5.1.3 condition, the damping ratio is taken as 5%.
The live load mass participation coefficient, n, is taken as 0.3 since the building is used as an office. The total mass of the building is given in the introduction of the dynamic analysis report. At the same time, G and Q are given for all floors one by one in the floor parameters section of the upper toolbar Analysis and Design tab.
