In order to quantitatively assess the effect of different infill wall construction methods on the seismic performance of reinforced concrete(RC)frames,domestic and foreign pseudo static test data of masonry infilled RC frames were collected,and a total of 68 specimens with detailed data in 19 literatures were selected as samples to analyze and compare the effects of three types of construction methods,namely,flexible connection of infill walls,integrity enhancement of infill walls,and installation of damping devices,on the strength,initial stiffness,ductility factor and equivalent viscous damping factors of the specimens.The results show that compared with the traditional construction methods,the strength and stiffness of specimens with flexible connection infill walls decrease,and the deformation capacity increases.The method of enhancing integrity can improve the strength,stiffness and deformation capacity,and it is a better method to reinforce the infill walls of existing buildings.The strength and stiffness of the structure with damping energy dissipation devices are reduced,but the deformation and energy dissipation capacity of the structure are improved,which can be used as a resilience improvement for new buildings if the construction cost is acceptable.
