阿图什人民医院分院门诊医技楼消能减震结构设计

Energy-dissipated structural design of outpatient medical technology complex of the Branch of Artux People's Hospital

以阿图什市人民医院门诊医技楼为工程实例,详细介绍了消能减震结构设计的过程。首先阐述了消能减震的必要性并根据初步计算设定了预期的减震目标,其次利用ETABS软件对非减震及减震结构进行了多遇地震下的时程分析,最后利用PERFORM-3D软件对减震结构进行罕遇地震下动力弹塑性分析,对结构的整体性能及关键构件的性能进行了评估,并阐述了关键构件的设计方法,同时通过对减震结构及非减震结构的对比分析,论证了设置阻尼器在罕遇地震下可以使结构有更大的弹塑性变形和强度储备,可以满足"大震不倒"目标。

The Outpatient Medical Technology Complex of Artux People＇s Hospital was taken as an example to introduce the design process of energy dissipation structural design. Firstly,the necessity of energy dissipation was expounded and energy dissipation target was set according to preliminary calculations. Then time-history analysis was conducted on the nondamping and damping structures under frequent earthquake using ETABS software. Finally dynamic elasto-plastic analysis was conducted on the structure under rare earthquake using PERFORM-3 D software. The performance of the overall structure and the key components of the structure were assessed,and the design method of key components was expounded.Through analysis and comparison of non-damping and damping structures,it demonstrates that the structure can have greater elastic-plastic deformation and strength reserve under rare earthquake by setting dampers,and the structure can meet the target of ＂not collapsing under rare earthquake＂.
