［摘要］依照工程设计图纸，按照相似比关系制作了1∶25的模型结构，选择两条场地天然波和一条人工波，进行了模拟振动台试验研究。研究了结构在7度小震～7度半大震下的地震响应，揭示了结构的抗震薄弱部位，并采用动力弹塑性分析进行了验证。试验和计算结果表明，结构满足小震不坏、大震不倒的抗震设防水准要求，转换结构以及框支柱为抗震薄弱部位，建议进行加强。

Abstract:A 1∶25 structure model according to the engineering design is made. Based on the two location natural seismic waves and one artificial seismic wave, the shaking table test was finished. Through shaking table test, the seismic response of structure model from 7 degrees low level earthquake to 7.5 degrees high level earthquake is studied, and the weak spot of the structure is found. The dynamic elasto-plastic computation analysis is carried out to verify shaking table test results. The results of the test and computation indicate that the structure satisfies the 3-level design objective, and the transfer story is the weak spot of the structure, suitable enhancement should be carried to that part.
Keywords:multi-tower tall building; connective structure; high transfer structure; shaking table test; dynamic elasto-plastic analysis
