Seismic Behavior of Steel Plate Reinforced Concrete Shear Walls

Abstract eng:
The steel plate reinforced concrete shear wall (abbreviated as SPRCW) is an innovative type of lateral force resisting structural member potentially used in steel-concrete composite structures in high-rise buildings, especially in earthquake-prone regions. This kind of walls is formed by inserting both steel plate and steel sections (eg. steel channels) into the ordinary RC shear walls. This paper presents an experimental study on the seismic behavior of such structural members. The test was conducted through the cyclic loading scheme on a series of models at 1:2 scale. The primary parameters vary in thickness of the steel plate, aspect ratio of the wall, and thickness of the SPRCW. In order to determine the influence and relative importance of different detailing on integrity between the steel plate and concrete component under service load, such details as lateral ties and welding studs on the steel plate are designed as well. The experimental program is developed to evaluate the damage patterns, hysteretic response, strength, stiffness and ductility behavior of the walls under constant axial compressive loads and cyclic horizontal forces. In addition, the experimental results of SPRCWs are compared with those of other three ordinary RC shear walls. Through this investigation, it is observed that steel plate and steel sections incased in the wall plays a major role in carrying loads, while concrete provides lateral restraint for steel plate, and therefore, prevent the steel plate from premature failure in stability and increases deformation capacity of the wall.
