［摘要］首钢演播厅结构设计中，根据建筑布局和功能的要求，采用滑动连接将演播厅分为大演播厅和中小演播厅两个部分。大演播厅结构复杂，存在多项不规则，采用两种分析软件进行小震的整体计算和校核；采用弹性动力时程分析进行包络设计；按D级性能目标，进行中大震下结构性能验算；采用SAUSAGE软件进行罕遇地震作用下的动力弹塑性时程分析，确保结构在大震作用下达到大震不倒的性能目标；针对楼面大开洞和窄楼面，进行楼板有限元应力分析，确保楼板的平面刚度。

Abstract:In the structural design  of Shougang  studio, according to the requirements of architectural layout and function, the studio was divided into two parts by sliding connections: the large studio and the small and medium-sized studio. The structure of the large studio was complex and there were many irregularities. Two kinds of analysis software were used to calculate and check the whole structure under the frequent earthquake. Elastic dynamic time-history analysis was used to conduct the envelope design. According to the D-class performance target, the structural performance under fortification and rare earthquakes was checked. The dynamic elastoplastic time-history analysis under rare earthquake was carried out by SAUSAGE software, to ensure that the structure could not collapse down under large earthquake. Finite element stress analysis was carried out for large opening and narrow floor slab to ensure the plane stiffness of the floor slab.

Keywords:Shougang studio;performance design;elastoplastic time-history analysis;stress analysis of floor slab
