（中國建筑科學研究院 北京 100013）[提要] 結(jié)合振動臺試驗現(xiàn)象和震害調(diào)查，對體型收進的框架結(jié)構(gòu)進行了深入的計算分析和比較，研究了體型收進對高層建筑結(jié)構(gòu)抗震性能的影響，對體型收進的位置、收進程度等影響因素進行了分析，并提出了帶有收進的高層建筑結(jié)構(gòu)設(shè)計時應(yīng)注意的問題。
[關(guān)鍵詞] 高層建筑 體型收進 抗震設(shè)計Shaking table test and earthquake reconnaissance reports are used to illustrate the damage of step back to the behavior of structures under seismic action. Linear dynamic time analysis and nonlinear static analysis are made to study the influence factors such as position of step back and size of step back. Some advices for the seismic design for structures with step-back are given.
Keywords: step back; seismic behavior; seismic design; tall buildings; push over
