11.41: Numerical investigation of influence of plate yield point on performance of steel plate shear wall

Abstract

Steel plate shear walls (SPSW) consist of thin infill steel plates attached to beams and columns in steel frames. SPSW are efficient lateral load resisting systems and can act as an alternative to traditional systems. In this study, the nonlinear response of single-story single-bay SPSW models having different yield points of infill plates (100, 180, 250 MPa.), were numerically investigated under lateral loading. The other variables in the analysis were the aspect ratio of panels (2 and 2.5), and thickness of the steel plates (3 , 5 and 7 mm.). The models were designed according to the "AISC Steel Design Guide 20" and the "AISC 341-10 Provisions". Finite element models of SPSWs were developed and analysed using ABAQUS nonlinear program. The results show that, using low yield point steel leads to more ductility and with some consideration influence the stiffness of models.

Numerical study on structural performance of corrugated steel plate shear wall with different yield points steel

“…An oblique tension band is found in the infill corrugated steel plate. These failure characteristics of the CSPSWs are similar to the results of Moammer et al [ 13 ] This condition indicates that when the infill corrugated steel plate enters the plastic stage, the additional lateral load is borne by the boundary frame. The frame is still elastic, and the tensile band formed by the plastic deformation of the corrugated steel plate contributes to the improvement of the structural bearing capacity.…”

“…Increasing the corrugation angle of test specimen results in the reduction in stiffness and energy dissipation. Moammer et al [ 13 ] investigated the influence of plate yield point (100, 180, and 250 MPa) on the performance of SPSW through finite element modeling (FEM). The use of LYP steel leads to high ductility and influences the stiffness of models.…”

Experimental Investigation into Failure Modes of Low-Yield-Point Steel Plate Shear Walls

“…Steel plate shear walls, consisting of embedded steel plates, vertical edge members (columns), and horizontal edge members (beams), have been adopted as one of the lateral load resisting systems in high-intensity seismic areas for the past 40 years. The excellent performance of steel plate shear walls in improving structural bearing capacity, stiffness, ductility, and energy dissipation capacity led to the widespread application of this system and different academic scholars have conducted experimental studies [1][2][3] and abundant simulation research [4][5][6][7] on steel plate shear walls, which was tremendously applied in engineering practice [8][9][10].…”
