Experimental Study on the Seismic Behavior of Concrete Composite Bearing Walls

Abstract:

Concrete composite bearing wall system is an innovated composite structure system, which is assembled by load-bearing walls, enclosure walls and thermal protection and insulation layers. Four concrete composite bearing walls were tested quasi-statically under low cyclic lateral loads. The characteristics including failure modes, hysteretic characteristics, ductility and stiffness degradation are investigated. It is shown that the concrete composite bearing walls possess high strength and ductility. In the elastic stage, the prefabricated slabs and frame could work together very well, and the composite walls exhibited enough stiffness against lateral deformation. With increasing horizontal load, the stiffness of the prefabricated slabs tended to decrease, and finally the composite wall system failed by flexural failure of frame structure with dense columns.
