带连体的学校超限高层结构设计

Structural design of an over-limited high-rise school building with the concatenates

介绍了一幢带连体的、平面和竖向均不规则的学校超限高层结构设计。针对连体结构桁架转换、竖向收进、楼板大开洞等引起的结构削弱,采用抗震性能化设计,对结构薄弱部位进行抗震加强,使结构的性能达到预期的目标,并对该类的超限高层抗震设计提供了参考。

Structural design of an over-limited high-rise school building with the concatenates,irregular plane and vertical irregularity is introduced.Aiming at the structural weakening caused by transfer truss of connecting structure,vertical setback and big openings of slab,performance-based seismic design is adopted to strengthen the weak position of the structure.The performance of the structure can reach the expected goal,and it provides a reference for the seismic design of this kind of high-rise buildings.
