［摘要］對保山市人民醫(yī)院高層住院樓的隔震與減震設(shè)計方案進行了分析比選，并介紹設(shè)置消能墻的減震設(shè)計方法。結(jié)果表明，在多遇地震下，結(jié)構(gòu)層間變形較小，消能器處于彈性工作階段，主要作用為給主體結(jié)構(gòu)提供一定的附加剛度；在設(shè)防地震及罕遇地震下，結(jié)構(gòu)層間變形較大，消能器先于主體結(jié)構(gòu)發(fā)生屈服，從而進入彈塑性工作階段，能利用軟鋼剪切變形耗散地震能量，從而降低結(jié)構(gòu)的地震響應(yīng)，提高結(jié)構(gòu)的安全儲備，同時具有較好的經(jīng)濟效益。［關(guān)鍵詞］消能減震設(shè)計; 消能墻; 動力彈塑性分析中圖分類號：U463，TU973 文獻標識碼：A 文章編號：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
