[摘要]  大懸挑或大跨度高層結(jié)構(gòu)在豎向地震作用下的結(jié)構(gòu)響應(yīng)較為明顯。針對某裙樓懸挑的B級高度高層建筑，考慮三向地震時(shí)程作用，對結(jié)構(gòu)進(jìn)行多向地震作用下的動力彈塑性時(shí)程分析，并對其抗震性能進(jìn)行評估，結(jié)果表明，結(jié)構(gòu)整體抗震性能較好，各構(gòu)件性能水準(zhǔn)均能滿足性能設(shè)計(jì)要求。

Abstract: It is obvious of the response for the long span high structure and cantilever structure under the vertical earthquake. Considering three directions earthquake action as for a B grade high arclutecture with a long cantilever podium structure, the structure aseismic performance is analyzed by the dynanuc elasto-plastic history analysis method. The result is that it is good performance for the whole structure indexes, and the key structure element state can satisfy the performance design requirement.
Keywords: high-structure; cantilever structure; elasto-plastic; vertical earthquake
