Summary

A single equation yield surface is presented under the combined action of bimoment and biaxial bending moments to model the plastification of structural I-sections. The proposed single yield surface equation represents a smooth, continuous and convex surface in three dimensional space. To verify the single equation yield surface, a finite element study is performed using LUSAS with four-noded isoparametric thick shell elements. When the verification of the yield surface equation was satisfactorily performed using finite element analysis, this technique was then used to fill the gaps which existed in a previous solution. The proposed single equation is easy to implement in a computer-based elasto-plastic analysis and is therefore recommended for general use.
