［摘要］寧夏衛(wèi)海財富大廈設(shè)計之初面臨扭轉(zhuǎn)嚴(yán)重、多遇地震下結(jié)構(gòu)層間位移角超標(biāo)等問題。采用同時安裝屈曲支撐、普通支撐和黏滯阻尼器的組合應(yīng)用消能減震方案，并進(jìn)行反應(yīng)譜計算和彈性及彈塑性時程計算。計算表明，多遇地震時通過發(fā)揮支撐的剛度調(diào)整功能和黏滯阻尼器的耗能功能，較好地解決了前述問題；罕遇地震時同時發(fā)揮屈曲支撐和黏滯阻尼器的耗能功能，較好地保護(hù)了主體結(jié)構(gòu)，實現(xiàn)了設(shè)計目的。該方案及其設(shè)計實現(xiàn)過程，對框剪結(jié)構(gòu)消能減震設(shè)計具有一定的借鑒意義。

Abstract:Facing design difficulty such as severe torsion， excessive displacement angle， and so on, the designer of Ningxia Weihai Fortune Tower adopts composite shock absorption scheme which suggest configuring of common brace， buckling-restrained brace and viscous damper simultaneously. And response spectrum calculation， elastic and elasto-plastic time history calculation were carried out. According to the calculation results， the above problems are solved by fully playing the stiffness-adjusting capability of braces and energy dissipation capability of dampers under frequent earthquake. And through playing energy dissipation capability of buckling-restrained braces and dampers under rare earthquake， the main structure is protected properly as expected. The scheme and the design procedure is of certain reference value to the design of the frame-shear wall structure.
Keywords:seismic energy dissipation; torsion; additional damper ratio; buckling-restrained brace; viscous damper
