以相似理论为基础,提出装配式巨子型有控结构体系(MSCSS)的模型设计方法,用振动台模拟地震激励对4巨层MSCSS进行缩尺模型试验。试验中用锤击法对模型进行模态分析,验证模型试验的可行性。通过采集MSCSS与巨子型框架结构(MFS)顶层的加速度响应结果,并与软件计算结果对比,表明振动台试验结果与有限元计算结果吻合度高,MSCSS较之MFS有较好的控制效果。
On the basis of similarity theory, a model design method of fabricated giant sub-type controlled structure system (MSCSS) is proposed. The 4 MSCSS giant scale model tests are simulated with shaking table simulation seismic excitation. In the experiment, the model was analyzed by the hammering method to verify the feasibility of the model test. The results of acceleration response of MSCSS and MFS top layer are compared with those of software. The results show that the test results of shaking table are in good agreement with the finite element calculation results. MSCSS has better control effect than MFS.
