Abstract

This article mainly studies the influence of changes in floor thickness under earthquake action on high-rise staggered building structures. Taking engineering examples as the research object, the structural model is a frame structure, and four types of finite element analysis models with plate thicknesses of 110mm, 120mm, 140mm, and 160mm are established. It compares the natural vibration period and mode of each structural scheme using the response spectrum analysis method, including the shearing force of each structural scheme, the seismic shearing force of each structural scheme, and the maximum floor displacement of the structure. The analysis results indicate that as a whole, it can be seen that the structure needs to meet the requirements of earthquake resistance and economic practicality. The plate thickness must not be too thin, and the thicker the better. In this project, a floor thickness of 140mm is sufficient, which can meet seismic requirements and is relatively economical.
