【摘要】 河南省人民医院新建病房楼结构设计涉及新建工程超限高层专项审查、既有高层建筑抗震鉴定及贴建电梯厅、为实现交通连接在新老高层建筑之间设置的高位架空连廊等内容。性能化设计中针对不同结构构件设定了合理的性能目标,采用多个软件进行对比分析,并通过构造措施对薄弱部位予以加强。高位架空连廊选用滑板支座实现弱连接,通过舒适度分析及竖向地震作用计算,保证其正常使用及承载的安全;风荷载及正常使用下的初始限位在支座设计中得到实现,有一定的工程推广价值。更多还原

【Abstract】 The structural design on the new ward building of Henan Provincial People’s Hospital is mainly to deal with an out-of-code high-rise building,the seismic evaluation of the existing building,the design of the elevator hall,the design of the elevated corridors between the existing building and the new building etc.Comparative analysis with multiple softwares and conceptual reinforcements were carried out to achieve seismic performance objectives.The sliding bearing was adopted as a weak link for the elevated corridors,the comfort checking and the vertical seismic analysis were done to guarantee the bearing capacity and the usage safety.In addition,the pre-set slide limit of the bearing was used under the wind load and the normal service condition,which could be a reference for similar projects.更多还原
