摘要
Abstract
In order to increase the in-plane strength and stiffness,and ductility of reinforced concrete frame,a new hybrid connection of installing steel brace frames within existing reinforced concrete frames is pro-posed.Three reinforced concrete frames with one floor and one span are modified,and the frame shear fail-ure behavior,overall bending failure,and shear slip failure behavior of the specimens are designed.The modified frame is tested under both horizontal cyclic load and vertical constant load simultaneously.The re-sults show that the proposed hybrid connection structure can effectively transfer the shear forces between the steel brace frames and reinforced concrete frames,and improve the shear strength of boundary rein-forced concrete columns through sandwich steel plates and high-strength bolts.In addition,a calculation method for estimating the direct shear bearing capacity of mixed connection methods is also proposed.关键词
