【摘要】：我国的高层建筑正在迅速发展,同时我国也是地震灾害多发国家。本文采用基于性能的抗震设计方法,以某超限高层的抗震性能分析和抗震设计为工程实例,以基于EPDA的PUSHOVR分析为手段,研究了框架-核心筒结构的弹塑性地震反应。本文主要工作如下：(1)对目前国内外弹塑性分析的研究现状和应用进行了总结与综述。(2) 以一个实际工程为例,进行了某超限高层的振动特性计算和反应谱分析,并进行了小震弹性设计和中震弹性及不屈服设计。(3)对该工程采用EPDA进行了静力推覆分析,得出结构的能力谱和各水准地震作用下的性能状况,及弹塑性发展情况。根据计算结果提出了结构相应的加强措施。
[Abstract]:High-rise buildings are developing rapidly in our country, at the same time, our country is prone to earthquake disaster.In this paper, a performance-based seismic design method is used to study the elastic-plastic seismic response of a frame-core tube structure by means of PUSHOVR analysis based on EPDA and taking the seismic performance analysis and seismic design of a certain over-limit high-rise as an engineering example.The main work of this paper is as follows: (1) the present research situation and application of elastoplastic analysis at home and abroad are summarized and summarized. Taking a practical project as an example, the vibration characteristic calculation and response spectrum analysis of a certain over-limit tall layer are carried out.The elastic design of small earthquake and the elastic and non-yielding design of moderate earthquake are carried out. The static and force nappe analysis of the project using EPDA is carried out, and the capacity spectrum of the structure and the performance of the structure under the action of various leveling earthquakes are obtained, as well as the development of elastic-plastic.According to the calculation results, the corresponding strengthening measures of the structure are put forward.
