Numerical analysis of bolted connections in cold-formed steel members

Abstract

This paper presents three-dimensional numerical models of bolted connections of cold-formed steel members. The purpose of three-dimensional numerical models is to evaluate the strength and the behavior of these connections. The computer code ANSYS v. 6.0, based on Finite Element Method, was used to analyze the numerical models response. In order to evaluate the efficiency and reliability of the constructed models, the numerical results were compared with experimental results obtained from experimental assays carried out in Structures Laboratory of EESC/USP. In this sense, the numerical results presented satisfactory agreement when compared with experimental results.
