Experimental and Numerical Analysis on Seismic Behavior of Composite Concrete and Double Steel Plates Shear Wall With Binding Bars


Abstract eng:
With the increase of building height and the advance function requirement of architecture, the higher performance demand of structural walls were proposed. Steel plate -concrete composite walls with binding bars are one of the new-style structural walls and have already been employed in the actual practice in recent years. The composite walls comprise of steel plates connected by an array of transverse binding bars using bolt connections and filled with concrete. In order to intensively investigate the seismic behavior of this new type of concrete filled double-steel-plate composite wall, The experimental and numerical analysis on seismic behavior of composite concrete and double steel plates shear wall with binding bars (CCSPW) subject to cyclic loading are discussed in this paper. Firstly, sixteen specimens are tested under large axial compressive force and reversed cyclic lateral load. The failure modes and deformation performance were observed. Valuable results were obtained for the hysteretic loops, shearing capacity, skeleton curves, ductility and other parameters. The surface steel and infill concrete can work compatibly by the binding bar connections in the whole process. All the specimens exhibited good energy dissipation ability and deformation capacity with full hysteretic curves and large ultimate drift ratios. Secondly, nonlinear finite element models were built with analytical software OpenSees. The simulations of hysteresis curves are conducted and the results agreed well with the test results. On the basis of that, parameter analyses of the CCSPW were carried out. Thirdly, the empirical formula to computing lateral shearing capacity and deformation of the composite shear walls with binding bars were derived by numerical fitting. And furthermore the hysteresis loop of the specimens under hysteretic load was confirmed by quantitative computation. The calculated value coincides well with the experimental value. All the experimental and numerical results indicate that the seismic performance of composite concrete and steel plate shear walls with binding bars is good and the seismic performance is enhanced with different factors. Some valuable results can give reference to the design and research of the new style shear walls.
