SEISMIC BEHAVIOR OF PRECAST REINFORCED CONCRETE WALLS

This study experimentally investigates the seismic behavior of precast reinforced concrete walls by test of large-scale specimens. The parameters of connected steel cover plate, orientation of wall reinforcements, steel ratio of wall, and strength of concrete were studied. The results show that the precast reinforced concrete wall can effectively increase the earthquake resistance of structures and protect the structural frame. The performance of the precast reinforced concrete wall can be fully developed by using connected steel cover plates with two channel plates which were fixed by M16 chemical anchors. The modified conventional reinforcement with more steel at the corners produces better performance than the other orientations. The larger steel ratio and stronger concrete also definitely increase the earthquake resistance of structures.
