摘要
以焦作中原商厦为原型建立缩尺模型并进行了模拟地震振动台试验以及有限元模拟研究,分析了该体系的自振特性、地震反应特征现象,特别对钢结构采用铰接节点和刚接节点的抗震性能进行了深入研究对比,对比试验与数值模拟结果发现,结构自振周期在低频域差异较大,在高频域较接近。
A scaled model was built based on Jiaozuo Zhongyuan Commercial Building for simulating seismic shaking table test,and the FEM analysis was carried out. The natural vibration characteristics,seismic responses and damage features of the model were recorded and analyzed. Moreover,the seismic behaviors of the steel frame structure using hinged joints and rigid joints were deeply studied respectively. Comparing the experiment data with the numerical simulation results,it was found that the natural vibration periods of the structure were different in the low frequency domain and similar in the high frequency domain.
