［摘要］提出一種框支剪力墻結(jié)構(gòu)消能減震策略——黏性液體阻尼器只布置在框支層。標(biāo)準(zhǔn)層剪力墻優(yōu)先布置在四角，其余部分可采用短肢剪力墻或框架柱，以減小扭轉(zhuǎn)響應(yīng)；黏性液體阻尼器僅提供阻尼，可在框支層靈活布置，與部分框支剪力墻相比，優(yōu)勢(shì)明顯。首先通過(guò)對(duì)1棟10層框支剪力墻結(jié)構(gòu)進(jìn)行彈性時(shí)程分析，驗(yàn)證了剪力墻布置策略是否恰當(dāng)；然后針對(duì)設(shè)計(jì)基本地震加速度為0.15g的1棟15層建筑案例，考慮7種設(shè)計(jì)方案進(jìn)行彈性與彈塑性時(shí)程分析。結(jié)果表明，采用消能減震措施后，框支剪力墻結(jié)構(gòu)的安全性可得到更好的保證。［關(guān)鍵詞］框支剪力墻結(jié)構(gòu); 消能減震; 平扭耦聯(lián); 時(shí)程分析中圖分類號(hào)：TU352.1， TU375.4 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2016)06-0043-06
Energy dissipation design of frame-supported shear wall structuresChen Min1, Chen Bowang1, Zou Yinsheng2(1 College of Civil Engineering and Mechanics, Central South University of Forestry and Technology,Changsha 410004, China; 2 College of Civil Engineering, Hunan University, Changsha 410082, China)Abstract:An energy dissipation design strategy for frame-supported shear wall structure was proposed, and in this method, viscous liquid damper was simply arranged in the frame supporting layer. Shear wall of standard layer was arranged in the four corners with priority, while the rest part might apply short limb shear wall or frame column to reduce the torsional response. Viscous fluid damper provided only damping, which could be flexibly arranged on the frame supporting layer and it had obvious advantages compared with partial frame-supported shear wall structure. First of all, elastic time-history analysis was carried out on a 10-story frame-supported shear wall structure building to verify the layout strategy of shear wall. And then seven design schemes were based on the design case of a 15-story building with the design basic seismic acceleration of ground motion being 0.15g to conduct the elastic and elastic-plastic time-history analysis. The results show that safety of frame-supported shear wall structure shall be better guaranteed after adopting energy dissipation measures.Keywords:frame-supported shear wall structure; energy dissipation; horizontal torsion coupling; time-history analysis
