Slabs are modeled linearly.
Basement shearwalls, linear or non-linear modeling option is under user control.
Analysis model is created automatically in the linear model option of basement shearwalls.
Under normal conditions, under the influence of earthquake loads, plastic deformation is not expected in floors and basement walls. For this reason, floors and basement walls are modeled with linear shell finite elements (shell) and the effective section stiffnesses are determined according to the coefficients marked in red in the picture below according to TBDY Table 4.2 .
Basement walls are modeled with shell finite elements in accordance with TBDY Article 4.5.3.7 . According to Article 5.4.4 of TBDY , basement walls are defined in accordance with the modeling rules applied in Section 4.5.5 , ie the DOT approach. It is explained in detail under the heading of "Modeling Basement Shearwalls" .
Non-linear modeling technique can also be used in basement curtains at the user's discretion. In non-linear modeling of basement curtainsThe Distributed Plastic Behavior Model is used. In the picture below, the three-dimensional building model, the linearly modeled analysis model of the basement walls and the analysis model of the basement walls using nonlinear modeling are seen, respectively.
