[摘要]將屈曲約束鋼板墻作為抗側力構件和耗能構件應用于鋼筋混凝土框架結構,即形成混凝土框架-屈曲約束鋼板墻結構體系。目前對這類結構在水平荷載作用下的位移限值并未進行研究,規(guī)范也無相關規(guī)定。利用模型試驗和數值模擬的方法,對混凝土框架-屈曲約束鋼板墻結構的受力性能進行了研究。分析了這種新型混合結構體系的受力過程與受力特點,并給出了彈性和彈塑性層間位移角限值的建議取值。建議混凝土框架-屈曲約束鋼板墻結構的彈性層間位移角限值取為1/600,彈塑性層間位移角限值取為1/50。
[關鍵詞]混凝土框架; 屈曲約束鋼板墻; 位移限值

Abstract:Buckling restrained steel plate shear wall (BRSPSW) can be used in reinforced concrete frame structure as lateral load resisting component and energy dissipating component. For this kind of new hybrid structure system, no research work on drift limit under lateral load has been conducted and there is no relevant specification. Using model test and numerical simulation method, the mechanical performance of reinforced concrete frame with buckling restrained steel plate shear wall was studied. The loading process and mechanical characteristics of reinforced concrete frame with buckling restrained steel plate shear wall was analyzed, and the elastic and elasto-plastic drift limit were proposed. It is suggested that the elastic and elasto-plastic inter-story drift limit of reinforced concrete frame with buckling restrained steel plate shear wall is 1/600 and 1/50 of the story height respectively.
Keywords:reinforced concrete frame; buckling restrained steel plate shear wall; drift limit
