Abstract

Abstract

Using finite element method, it is analysed and studied the secondary stress in the member bar of cold-formed thin-wall steel truss due to node geometric flaw. It is also analysed that the secondary stress values and regularities of distribution as well as the reason of generating secondary stress and its effect on cold-formed thin-wall steel truss structure.
