| 摘 要： | 随着现代建筑高度的不断增加，混合结构体系在超高层建筑中逐步广泛应用，因此对该结构体系在地震作用下的破坏机理和抗震性能展开深入的研究是一项有意义的工作。本文对一混合结构体系复杂超高层建筑进行1／35的模型模拟地震振动台试验，分析模型结构的动力特性和不同烈度地震作用下加速度、位移和应变反应，然后根据相似关系推算出原型结构的动力特性和反应，研究其在各水准地震作用下的破坏机理和破坏形式，最后对原型结构设计提出若干建议。

| Abstract: | The use of hybrid structural system is becoming more and more extensive in modern high-rise buildings with the increasing structure height, thus it is becoming an important work to explore the failure mechanism and seismic behaviour of this system under earthquake. A 1/35 scale model of a hybrid high-rise building is tested on shaking table to study the seismic behavior of the prototype structure in this paper. The dynamic characteristics and the model response of acceleration, deformation and strain under different earthquake intensities are analyzed. Then the dynamic characteristics and response of prototype structure are calculated according to the similitude relation, and the failure mechanism and the cracking pattern under different earthquake intensities are discussed as well. Finally some suggestions for engineering design are put forward. |
