Experimental study on behavior of precast shear wall using post-cast at the connection

Abstract

The seismic behavior of precast concrete structure wall mainly depends on connection of the shear walls, and constrains at edge elements. The strength of concrete in embedded column area is also especially important. This paper explores a mothod of connection for prefabrication that was post-cast at the connection when the precast wall was assembling. To investigate the failure mechanism of this kind of precast shear walls, a precast concrete wall specimen is studied and tested in this paper. Test results indicate that this kind of connection may effectively improve the behavier of precast shear walls, and ensure that the seismic performance of the precast walls can be equated with cast-in-place specimen.
