［摘要］基于現(xiàn)有的研究理論，對超高層結(jié)構(gòu)各主要受力構(gòu)件的彈塑性參數(shù)設(shè)置進(jìn)行探討。在對超高層結(jié)構(gòu)進(jìn)行動(dòng)力彈塑性時(shí)程分析時(shí)，采用“直接法”和“間接法”兩種方法對結(jié)構(gòu)“大震不倒”進(jìn)行判斷，并對兩種方法按包絡(luò)取值。對結(jié)構(gòu)損傷提出了一種新的基于《建筑抗震設(shè)計(jì)規(guī)范》（GB 50011—2010）的判別方法，并與美國FEMA 356規(guī)范判別方法進(jìn)行對比。以蘇州綠地中央廣場項(xiàng)目辦公樓為工程背景，采用PERFORM-3D軟件對其進(jìn)行7度大震下動(dòng)力彈塑性時(shí)程分析，從宏觀上評價(jià)該結(jié)構(gòu)體系的抗震性能。通過對比發(fā)現(xiàn)，《建筑抗震設(shè)計(jì)規(guī)范》（GB 50011—2010）對結(jié)構(gòu)抗震性能評估與美國FEMA 356規(guī)范相比更加偏于安全。

Abstract:Some discussions on the setting of elastic-plastic parameters of main components were included based on current theories. In dynamic elastic-plastic time-history analysis of the structure, two methods of“direct method” and “indirect method” were adopted to estimate that if the seismic fortification standard of “no collapse under rare earthquake” can be achieved. Envelop values of two methods were obtained. A new discriminated method about the structure damage was proposed based on Code for seismic design of buildings(GB 50011—2010).The new evaluation method was compared with the method of American FEMA 356 code. Suzhou Green Central Plaza project was selected as research object. The dynamic elastic-plastic time-history analyses on the super high-rise building under the rare earthquake of 7 degree intensity were carried out by PERFORM-3D software to evaluate the seismic performance of the structural system. The comparison between seismic performance evaluation of Code for seismic design of buildings(GB 50011—2010) and American FEMA 356 code indicates that the former is safer.

Keywords:dynamic elastic-plastic time-history analysis; no collapse under rare earthquake; PERFORM-3D software； seismic performance evaluation
