Net section resistance in bolted cold-formed steel angles under tension
Abstract Net section resistance in bolted cold-formed steel angles of members under tension is analyzed in this work. The efficiency reduction due to shear lag and eccentricity effects in bolted connections is studied using finite element models implemented in ABAQUS software. The nonlinearities of the steel material and the contact between elements are considered in the numerical models, and their results are in good agreement with experimental tests. A parametric study is conducted in this work using Finite Element (FE) analyses. A large number of experimental tests reported in the literature is also summarized in this work. A new expression of easy application for net section reduction coefficient is found, which allows improving the prediction of the nominal resistance of the net section.
Highlights A new equation for the net-section resistance in bolt connections is presented. The results obtained from FE analyses were verified against experimental results. The influence of different parameters on the net-section resistance was analyzed. In this research an extensive experimental database from several researchers was used. The accuracy of the AISI and EC-3 to estimate the net-section resistance in bolt connections was verified.
