［摘要］岚山文化中心工程主体结构为钢筋混凝土框架-剪力墙结构，长、宽均为144-8m，设防震缝将整个建筑分为五个独立的结构单元。因建筑功能，本结构存在扭转不规则、凹凸不规则、楼板不连续、尺寸突变、构件间断及其他不规则等多项不规则的情况。重点阐述了本工程结构超限对应的处理措施，对本工程中的大跨度构件、长悬臂构件进行受力分析，对薄弱楼板进行中震作用下的应力分析。分析结果表明，本工程满足既定的抗震设防目标。

Abstract:The main structure of Lanshan Cultural Center is reinforced concrete frame-shear wall, with length and width of 144-8m respectively. The whole building is divided into five independent structural units by seismic joints. Due to the building function, there are many irregularities in the structure, such as torsion irregularity, concave convex irregularity, floor discontinuity, size mutation, component discontinuity and other irregularities. The treatment measures corresponding to the out-of-code conditions of the engineering structure were emphatically described. The mechanical analyses were carried out on the large-span members and long-cantilever members in the project, and the stress analysis was carried out on the weak slab under the fortification earthquake. The analysis results show that the project meets the established seismic fortification goals.

Keywords:Lanshan Cultural Center； out-of-code structure; large span; long cantilever; weak slab
