Optimization of Seismic Performance of Staggered Layer Structures Based on SATWE Software Plate Thickness

Abstract

In this paper, based on the seismic effect, the influence of the change of floor thickness on the seismic performance of high-rise staggered-story buildings is studied. Taking an engineering example as the research object, the structure model is established by SATWE software. Four kinds of finite element analysis models with thicknesses of 110 mm, 120 mm, 130 mm, and 150 mm are established. The elastodynamic time history analysis method is used to compare the maximum floor displacement of each structural scheme, the floor displacement angle of each structural scheme, and the lateral stiffness of each structural scheme. The analysis results show that with the increase in floor thickness, the maximum floor displacement, floor displacement angle, and lateral stiffness of the structure tend to increase. The following conclusions can be drawn.: the structure must not be too thin behind the slab, nor the thicker the better to meet the seismic require-ments. In this project, the floor thickness of 130mm can meet the seismic re-quirements and is comparatively economical.
