[摘要] 寧夏大劇院為平面不規(guī)則和豎向不規(guī)則的復(fù)雜建筑結(jié)構(gòu)，本文闡述了寧夏大劇院的結(jié)構(gòu)設(shè)計(jì)思路。通過對(duì)結(jié)構(gòu)進(jìn)行彈性分析，發(fā)現(xiàn)該整體結(jié)構(gòu)均處于彈性狀態(tài)；對(duì)結(jié)構(gòu)進(jìn)行彈塑性分析，發(fā)現(xiàn)結(jié)構(gòu)在罕遇地震作用下的薄弱環(huán)節(jié)和薄弱部位，并對(duì)其進(jìn)行針對(duì)性的結(jié)構(gòu)加強(qiáng)；進(jìn)而滿足抗震規(guī)范規(guī)定的“三水準(zhǔn)”、“兩階段設(shè)計(jì)”。

Abstract: Ningxia theater is one of the complex structures for irregular plane and vertical irregular, this paper expounds the structural design concept of Ningxia grand theater. Based on the structure of the elastic analysis, this paper found that the overall structure is in elastic state; based on the structure of the elastic and plastic analysis, this paper found that the structure under seldomly occurred earthquake weak links and weak position, and cames on the targeted structure strengthening; seismic code provisions to meet the "three level" and "the two stage design".

Keywords: complex structure; elastic analysis; Pushover; performance control point
