Experimental and numerical study on shear resistant behavior of double-corrugated-plate shear walls
Abstract Double-corrugated-plate shear wall (DCPSW), which is composed of two identical corrugated plates and assembled by connecting bolts, is an innovative type of lateral force resistant device for high-rise building structures. In this paper, the shear resistant behavior of the DCPSW is investigated via tests and additional finite element (FE) parametric study. First, the test results of two DCPSW specimens subjected to monotonic in-plane shear loads are reported. Second, FE models are introduced to perform simulations on the shear resistant behavior of the test specimens; it is seen that the numerical results fit well with the test results, and hence the FE models for simulations of the DCPSWs are validated. Then, an additional parametric study is presented by changing the geometrical parameters including aspect ratio, bolt column number, corrugation amplitude and dimensions of boundary elements of the DCPSWs. As a result, the effects of these parameters on the shear resistant behavior of the DCPSWs are further revealed. It is shown that the ultimate shear resistance of the DCPSWs increases with the increase of aspect ratio, bolt column number and corrugation amplitude, yet the dimensions of the boundary elements have little effect on the shear resistance of the embedded corrugated plates. Finally, by analyzing the results of the parametric study, some design remarks are concluded to provide valuable references for the design of the DCPSWs in practice.
Highlights DCPSWs achieve better stability behavior under shear loads over ordinary CPSWs. Tests of two DCPSW specimens subjected to monotonic shear loads are reported. Global buckling failure mode governs the failure of the DCPSW. FE models are validated to well predict the shear resistant behavior of the test specimens. Parametric study was performed to reveal the effect of design parameters on shear resistant behavior.
