［摘要］对保山市人民医院高层住院楼的隔震与减震设计方案进行了分析比选，并介绍设置消能墙的减震设计方法。结果表明，在多遇地震下，结构层间变形较小，消能器处于弹性工作阶段，主要作用为给主体结构提供一定的附加刚度；在设防地震及罕遇地震下，结构层间变形较大，消能器先于主体结构发生屈服，从而进入弹塑性工作阶段，能利用软钢剪切变形耗散地震能量，从而降低结构的地震响应，提高结构的安全储备，同时具有较好的经济效益。［关键词］消能减震设计; 消能墙; 动力弹塑性分析中图分类号：U463，TU973 文献标识码：A 文章编号：1002-848X(2016)08-0033-04
Energy dissipation analysis and design of high-rise inpatient building of Baoshan People's HospitalZhan Hua, Gao Yong(Yunnan Design Institute Group, Kunming 650228, China)Abstract: The energy dissipation design schemes of high-rise inpatient building of Baoshan People's Hospital were analyzed and compared. The energy dissipation design method of the energy dissipation wall was introduced. The results show that under the frequent earthquake, the energy dissipation wall can effectively provide certain additional stiffness to the main structure and it is in elastic working stage. In addition, the structure with energy dissipation wall has small inter-layer displacement. Under the fortification or rare earthquake, the structure with energy dissipation wall has large inter-layer displacement. The energy dissipation wall yields before the main structure and enters into elastic-plastic stage. The energy dissipation wall can dissipate seismic energy by soft steel shear deformation, thus lowering seismic response of the structure and improving safety reserve of structure, which is better economic benefit.Keywords: energy dissipation design; energy dissipation wall; dynamic elastic-plastic analysis
