【摘要】：我國的高層建筑正在迅速發(fā)展,同時我國也是地震災(zāi)害多發(fā)國家。本文采用基于性能的抗震設(shè)計方法,以某超限高層的抗震性能分析和抗震設(shè)計為工程實例,以基于EPDA的PUSHOVR分析為手段,研究了框架-核心筒結(jié)構(gòu)的彈塑性地震反應(yīng)。本文主要工作如下：(1)對目前國內(nèi)外彈塑性分析的研究現(xiàn)狀和應(yīng)用進(jìn)行了總結(jié)與綜述。(2) 以一個實際工程為例,進(jìn)行了某超限高層的振動特性計算和反應(yīng)譜分析,并進(jìn)行了小震彈性設(shè)計和中震彈性及不屈服設(shè)計。(3)對該工程采用EPDA進(jìn)行了靜力推覆分析,得出結(jié)構(gòu)的能力譜和各水準(zhǔn)地震作用下的性能狀況,及彈塑性發(fā)展情況。根據(jù)計算結(jié)果提出了結(jié)構(gòu)相應(yīng)的加強(qiáng)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.
