［摘要］商丘文化藝術(shù)中心大劇院存在扭轉(zhuǎn)不規(guī)則、樓板不連續(xù)、豎向構(gòu)件間斷、存在局部穿層柱、斜柱等超限不規(guī)則項。針對結(jié)構(gòu)體系的特點(diǎn)，給出了結(jié)構(gòu)抗震性能化設(shè)計目標(biāo)。詳細(xì)介紹了商丘文化藝術(shù)中心大劇院抗震性能化設(shè)計方法和針對超限不規(guī)則項所采取的加強(qiáng)措施。對結(jié)構(gòu)進(jìn)行了反應(yīng)譜分析、彈性時程分析和大震動力彈塑性分析，并對內(nèi)外球結(jié)構(gòu)、觀眾廳頂及主舞臺頂桁架、舞臺臺口支承梁等重點(diǎn)部位進(jìn)行了專項分析，結(jié)果表明結(jié)構(gòu)滿足抗震性能化設(shè)計目標(biāo)的要求。

Abstract:There are irregular torsion, discontinuous floor, discontinuous vertical components, partial cross-story columns, inclined columns and other out-of-code irregular items in Grand Theater of Shangqiu Culture and Art Center. According to the characteristics of the structural system, the structural performance-based seismic design objectives were provided. The performance-based seismic design method and the strengthening measures for the out-of-code irregular items of the Grand Theatre of Shangqiu Cultural and Art Center were introduced in detail. Response spectrum analysis, elastic time-history analysis and dynamic elasto-plastic analysis under rare earthquake were carried out. Special analyses were made on key parts such as inner and outer spherical structure, auditorium roof and main stage roof truss, stage mouth supporting beam, etc. The results show that the structure meets the requirements of performance-based seismic design objectives.
Keywords:out-of-code structure; performance-based seismic design; dynamic elasto-plastic analysis; single-layer spherical shell; vertical discontinuity
