Experiment on Seismic Behavior of RC Composite Core Walls With STRC Columns and Concealed Meshed Steel Trusses

A 1/7 scale composite core wall specimen designed from a pratical engineering was tested under low-frequency cyclic loading.The hysteretic characteristics,load-carrying capacity,ductility,stiffness and its degradation process,failure pattern of the specimen were analyzed based on the test.The related anti-seismic constructional measures were given after the weakness part of the specimen was analyzed.The results show that the load-carrying capacity and the ductility of the core walls could be improved greatly by combining the STRC columns as the borders and concealed steel trusses in the walls.
