REVIEWS ON OUT-OF-PLANE SEISMIC BEHAVIOR OF INFILLS AFTER RETROFIT
As maintenance elements in reinforced concrete frame structures,infills are connected to the main struc-ture through tie bars for improving the stiffness of the main structure,which has been gradually emphasized. The state of art for infills mainly focuses on in-plane seismic performance,however,seismic investigations show that out-of-plane collapse is observed,resulting in safety hazards. Thus,investigations on infills retrofit and out-of-plane behavior after retrofit are necessary. In this paper,the seismic performance of retrofitted infills is intro-duced retrofit materials,end anchorage,connection method between infill walls and RC frames. Seismic performance of reinforced infill walls is obtained,and the problems in the existing studies are analyzed.
