不同高度结构地震响应特性研究
|
摘要
通过对结构平面布置相同、高度不同的高层结构在相同地震作用下的结构地震响应特性分析和研究,探讨了高层建筑结构地震响应的特点。对某一高层剪力墙结构的地震响应特性进行了研究,并选取振动台试验结果进行验证。分析结果表明,对于高度超过150m的高层结构,在大震作用下结构上部易发生损坏,应对结构中上部采取适当的加强措施。
The seismic response characteristics of the structures,with the same layout and different height,undergoing the same earthquake,are discussed. Based on the analysis of a high-rise shearwall structure and the results of shaking table test,it is shown that the damage mostly occurs in the middle and upper part of tall building exceeding 150 meters under the rare earthquake action, and it should be strengthened by proper measures.
