为了研究巨-子结构控制体系的抗震性能,该文进行了巨-子结构控制体系的振动台试验研究。试验模型均为钢框架模型且包括三个不同的模型,分别称为抗震结构模型、隔震结构模型和隔震-底层固结模型。采用大型有限元软件SAP2000对试验模型进行了非线性时程分析,并在主结构的加速度、层间位移,子结构的层间位移以及隔震层的变形方面与试验结果进行了对比分析。结果表明:理论分析与试验研究结果吻合较好,且不论是理论计算结果还是试验实测结果,隔震结构以及隔震-底层固结结构相对于抗震结构而言,结构的响应减小明显,说明结构施加隔震装置后能有效减小结构响应,从而保证结构的安全性。
In order to study the seismic performance of the giant-substructure control system, a shaking table test of the giant-substructure control system is carried out. The experimental models are all steel frame models and include three different models, namely the seismic model, the isolation structure model and the isolation-bottom consolidation model. The large-scale finite element software SAP2000 is used to conduct nonlinear time history analysis of the test model. The main results are compared with the experimental results in terms of acceleration of the main structure, interlayer displacement, interlayer displacement of the sub-structure and deformation of the isolation layer. The results show that the theoretical analysis is in good agreement with the experimental results, and the response of the structure decreases obviously whether it is the theoretical calculation result or the experimental measurement result, and the isolation structure and the isolation-basement consolidation structure relative to the seismic structure Structure after applying isolation device can effectively reduce the structural response, so as to ensure the structural safety.
