钢框架—混凝土核心筒结构在地震作用下的模拟分析

Simulation Analysis of Steel Frame Hybrid-reinforced Concrete Core Wall Structure under Seismic Action

采用三维有限元ANSYS软件,对常见的一种高层结构形式:钢框架—混凝土核心筒混合结构,进行了模态分析和地震时程反应分析,得到了该种建筑物的自振特性以及它在地震作用下的位移和加速度反应。计算结果有助于工程技术人员理解此类结构在地震作用下的反应,对高层结构的抗震设计和研究提供一定的参考价值。

By using three-dimensional ANASYS software, this paper describes the modal analysis and the seismic time-history analysis to a high-rise structure of steel frame hybrid-reinforced concrete core wall structure. The vibration characteristics of the building and its displacement and acceleration responses are gotten under earthquake. The algorithm results are helpful for engineers and technicians to understand the response of this kind of structure under earthquake, and will provide some reference to the seismic study and design of high-rise structure.
