A Discussion on the Design of Buildings with Rigid Basement According to TBSC 2018

Turkish Building Seismic Code (TBSC), which was published in 2018 and became effective 2019 prescribes a two-stage loading method for designing of building with rigid podium. In the first stage, podium is modeled as massless structure only mass superstructure considered modal response spectrum analysis. The seismic design forces are computed using this model appropriate modification coefficient overstrength factor. second system addition, superposed those Due to use separate models analyses superposition need, process relatively cumbersome, complex prone errors. study, based on structural analysis results, some considerations recommendations presented modeling buildings
