Abstract

This paper describes a new formulation for the elasto-plastic large displacement analysis of thin-walled members and frames. The proposed formulation is one-dimensional but facilitates the detailed modelling of any open cross-section, including the effects of the spread of plasticity and stress/strain reversals. This is achieved through the use of monitoring points over the cross-section where direct material strains are evaluated and the corresponding stresses are established according to any stress-strain relationship. Examples using ADAPTIC demonstrate the accuracy of the proposed formulation and its applicability to the study of the inelastic response of thin-walled structures subject to lateral torsional instability.
