摘　　要：浙江某应急酒店项目由A,B两座塔楼通过顶部大跨连廊连接,连廊采用钢桁架结构形式,净跨约34.5 m,该项目结构因多项“不规则”而为超限结构。为达成预定的抗震性能目标,对结构的各“不规则”项采取了有针对性的设计加强策略。采用YJK和PMSAP两种计算分析软件,对连体结构进行对比,通过性能化设计和动力弹塑性时程分析,探究结构在设防地震及罕遇地震条件下的响应特性。再针对连廊部分,进行舒适度及温度应力等专项分析。基于计算与分析结果,针对结构核心关键部位以及结构薄弱部位实施有效加强策略,达到既定的抗震性能化设计目标,确保了结构的安全与可靠。A certain emergency hotel project in Zhejiang Province is connected by two towers A and B through a large-span connecting corridor at the top.The connecting corridor adopts a steel truss structure,with a net span of about 34.5 meters.The structure of the project is an over limit structure due to multiple“irregularities”.To achieve the predetermined seismic performance goals,we have adopted targeted design strengthening strategies for various“irregular”items of the structure.Subsequently,two different mechanical models,YJK and PMSAP,were used to compare and analyze the seismic performance of the connected structure.Then,through performance-based design and dynamic elastoplastic time history analysis,the response characteristics of the structure under seismic fortification and rare earthquake conditions were explored.Finally,a special analysis will be conducted on the comfort and temperature stress of the corridor section.Based on the calculation and analysis results,we have implemented effective strengthening strategies for the core key parts and weak parts of the structure,achieving the established seismic performance design goals and ensuring the safety and reliability of the structure.
