Resistance Of Members Subjected To Combined Loads According To EC3 And EC9
Published 2017 · Engineering
The aim of this article is to describe problems of members subjected to biaxial bending and axial compression force and the methods of their design. Members subjected to bending moments about two axes and axial compression force exhibit complex behavior. It is necessary to consider second order theory and imperfections when designing members like that, since they have noticeable influence on resistance in instability. There are examples shown in the article, using methods present in current European standards EN 1993-1-1 and EN 1999-1-1. Attention is drawn to differences in methods, both in applicability and practicality, in design of members with constant and linear bending moment. The purpose of presented paper is to show if the method, which is currently used in Eurocode for aluminum structures, can be also used for steel structures.
