[摘要]福建省莆田市某商住樓為一高位轉(zhuǎn)換超限高層建筑，總高度86.8m，存在平面凹凸不規(guī)則、扭轉(zhuǎn)不規(guī)則、豎向抗側(cè)力構(gòu)件間斷、體型豎向收進(jìn)等超限情況。采用了抗震性能化方法對(duì)結(jié)構(gòu)各關(guān)鍵構(gòu)件進(jìn)行設(shè)計(jì)；采用了多種軟件對(duì)主體結(jié)構(gòu)進(jìn)行小震彈性、中震彈性和不屈服、大震彈塑性分析；將主樓帶裙房和不帶裙房進(jìn)行了單獨(dú)建模，比較分析以保證主樓自身的剛度和強(qiáng)度要求；還采取了比現(xiàn)行規(guī)范更為嚴(yán)格的抗震措施。計(jì)算結(jié)果表明，該結(jié)構(gòu)總體指標(biāo)均能滿足規(guī)范要求，可以達(dá)到預(yù)期的抗震性能目標(biāo)。

Abstract: The commercial and residential building, in Putian City, Fujian Province is a high-rise building beyond code- specification with high transfer story and the building’s height is 86.8m. Some conditions beyond code-specification as follows, irregular plane and reverse, discontinuous vertical lateral load resistance members and vertical structural setback. Performance-based seismic design method was used to design the key structural members in the engineering; The main structure was analyzed by different software , including elastic analysis under frequently occurred earthquake, elastic and nyield analysis under fortification earthquake, elasto-plastic analysis under rarely occurred earthquake; In order to ensure the requirements of stiffness and strength of main building, calculation models of main building with and without annex were comparative analyzed. In addition, more strict anti-seismic measures than the current criterions were adopted. The result shows that the structure can satisfy the requirement of criterions in overall index and can achieve the expected seismic performance objectives.

Keywords: high-rise building beyond code-specification; high transfer; performance-based seismic design
