Abstract

Elastoplastic local buckling of beams is a phenomenon that can potentially lead to the collapse of structures. It has been analysed in previous attempts; however, this research focuses on issues omitted in the past, such as the influence of the member's length. The elastoplastic behaviour is evaluated using the recently proposed elastic local buckling load factor. This factor allows for the consideration of the flange-web interaction and the influence of the beam's length to precisely estimate the beam's rotation capacity, ultimate strength ratio, and energy dissipation capacity. A novel method of classification is proposed. The research is based on numerical analysis and an experimental results database.
