Mechanical Performance between the Embedded Steel Plate and the Concrete in Composite Shear Walls
In order to strengthen the co-work performance between the steel plate and concrete, the anchorage construction of arrayed studs were welded on both sides of the plate according to a super high-rise building in Beijing. 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 thickness of the concrete wall, the thickness of steel plate, the diameter, the length and the amount of the studs and the rate of reinforcement for distributing bars in the walls were considered. The shear bearing capacity, load-slip relationship, strains of the steel plate and studs, mechanical properties and failure mode were analyzed. The effect of stud layout on the coordinate work of the concrete plate was studied. Results show that the shear bearing capacity is obviously improved by using smaller diameter studs or decreasing the distance between studs when the total area of studs is kept unchanged. The thickness of the steel plate 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 4. A simplified mechanics calculated method to estimate the shear bearing capacity of this kind of shear wall was put forward. And the calculated results are in good agreement with the experimental results.
