Abstract

Cold-formed steel (CFS) framed shear walls with steel sheet sheathing can achieve higher shear resistance compared to conventional CFS framed shear walls. Experimental and numerical investigation of seismic behavior was present on two CFS shear walls sheathed with steel sheet for the base layer combined with gypsum wallboards for the face layer on both sides. Monotonic shear and cyclic loading tests were conducted on wall specimens. The failure mechanism, bearing capacity, stiffness and ductility of specimens were obtained. On the basis of rational simplification of CFS framed shear walls, the finite element software ABAQUS was used to simulate the monotonic behavior of CFS shear walls and the structural analysis software OpenSees was used in developing and calibrating 2D models of reversed cyclic shear wall test. A comparison between the numerical simulations and the test results showed a good agreement between the results of the numerical studies and the test results. The conclusions of this study can be applied to the seismic design of CFS framed shear walls.

Seismic Performance Investigation of Cold-Formed Steel Framed Shear Walls with Steel Sheathing

Cold-formed steel (CFS) framed shear walls with steel sheet sheathing can achieve higher shear resistance compared to conventional CFS framed shear walls. Experimental and numerical investigation of seismic behavior was present on two CFS shear walls sheathed with steel sheet for the base layer combined with gypsum wallboards for the face layer on both sides. Monotonic shear and cyclic loading tests were conducted on wall specimens. The failure mechanism, bearing capacity, stiffness and ductility of specimens were obtained. On the basis of rational simplification of CFS framed shear walls, the finite element software ABAQUS was used to simulate the monotonic behavior of CFS shear walls and the structural analysis software OpenSees was used in developing and calibrating 2D models of reversed cyclic shear wall test. A comparison between the numerical simulations and the test results showed a good agreement between the results of the numerical studies and the test results. The conclusions of this study can be applied to the seismic design of CFS framed shear walls.
