Cyclic shear tests of steel double layer truss walls

This paper first describes the inelastic buckling behavior of three steel truss walls for cyclic in-plane shear deformation. Two of the walls were double layer diagonal trussed walls and one was single-layer wall without out-of-plane rigidity. Evaluation of buckling and post-buckling strength is the second topic. In each test, significant member buckling was observed but post-buckling strength was stable. The actual buckling length was shorter than the ideal member-axis model due to bending rigidity of joints. It was calculated with a linear buckling analysis modeling the joint. © Architectural Institute of Japan. All rights reserved.
