摘要
本文对轻型钢框架-支撑结构模型进行地震模拟振动台试验,并运用SAP2000软件进行数值模拟分析。模型结构为1∶3缩尺模型,分别在Taft波、Kobe波、人工波3种地震波作用下进行振动台试验,得到结构的加速度反应值,同时在同样的工况作用下做时程分析,得到结构的加速度反应值和位移反应值。将试验值和模拟值相互对比分析,找出结构的薄弱部位,研究该结构体系的抗震性能和破坏机理,完善轻钢框架-支撑结构体系的抗震设计。
The seismic simulation shaking table test of a light steel frame-bracing structure model is studied, and the numerical simulation analysis is conducted using SAP2000 software. The model, which is a 1 ： 3 scale model, is tested under three kinds of seismic waves ： Taft wave, Kobe wave and Artificial wave, and the acceleration response values of the structure are obtained. At the same time, by the time-history analysis of the model under the same conditions, the acceleration response values and the displacement response values of the structure are acquired. The weak parts of the structure are identified by comparative analysis between the experimental values and simulated values, and the seismic performance and failure mechanism of the structural system are studied in order to improve the seismic design of light steel frame-bracing structural system.
