摘　　要：青浦题学平和学校图书剧场由图书馆、剧场、多功能厅等组成,主体结构采用钢框架结构体系,楼盖采用现浇混凝土楼板+局部大跨钢网架屋盖,楼板采用钢筋桁架楼承板。整体结构存在平面及竖向多项不规则,结合《建筑抗震设计规范》(GB 50011—2010)要求,采用三水准、两阶段设计方法,对结构进行弹性和弹塑性分析。分析结果表明:整体结构具有良好的承载和变形能力,能满足“小震弹性,中震可修,大震不倒”的抗震性能化设计目标。对结构的薄弱部位提出了有效的抗震加强措施。针对超长结构温度应力、剧场入口水平大悬挑及图书阅览区大跨度楼盖舒适度、剧院入口悬挑区域施工模拟分析、关键节点应力、声学设计对结构设计的影响等进行了专项分析。library theatre of Pinghe Bilingual School Qingpu is composed of library,theater,multi-function hall,etc.The main structure adopts steel frame structure system,the floor adopts cast-in-place concrete floor and local large-span steel grid roof,and the floor slab adopts steel truss floor bearing plate.The overall structure has multiple irregularities in the horizontal and vertical plane.Combined with the requirements of Code for seismic design of buildings(GB 50011—2010),the elastic and elastic-plastic seismic analyses of the structure were carried out by using the method of three levels and two stages.The analysis results indicate that the whole structure has good bearing and deformation ability,and it can reach the seismic performance design aims of elasticity under small earthquake,restoration under medium earthquake and noncollapse under large earthquake.The effective seismic strengthening measures to weak parts of structure were suggested.Technological analysis was carried out on the super-long structural temperature stress,comfortable degree of the large horizontal overhanging at the entrance of the theatre and the large-span floor of the reading area of the library,construction simulation analysis of overhanging area at the entrance of the theatre,key node stress,influence of acoustic design on structural design.
