Performance of Co-work Between Steel Plate With Studs and Outer Reinforced Concrete in Shear Wall

Eighteen specimens of embedded steel plate concrete shear walls with arrayed studs were tested by pushing out under monotonic loading in this paper.Some parameters,such as the diameter,the length,and the amount of studs,the thickness of the concrete wall,the thickness of steel plate and the rate of reinforcement for distributing bars in the walls are considered.The shear bearing capacity,load-slip relationship,strains of the steel plate and studs,and development of concrete cracks are analyzed.The mechanical properties,failure modes,and the effect of stud layout on the coordinate work of the concrete plate are studied.Experimental study shows that the shear bearing capacity is obviously improved by using smaller diameter studs,decreasing the distance between studs when the total area of studs does not change.The thickness of the concrete wall should be thick enough to meet the basic requirements.However,the variance of the steel plate thickness has almost no effect on the shear bearing capacity.The ratio of the length to the diameter of the studs should be not less than four.A simplified mechanics computing method to estimate the shear bearing capacity of this kind of shear wall is put forward.
