Fibre-Based modelling for predicting the progressive collapse of cylindrical shells under combined axial compression and bending moment

Cylindrical shell is a fundamental building block of many engineering structures. They are usually designed to be the primary load-carrying components withstand different combinations environmental loads. This paper presents fibre-based approach modelling progressive collapse cylindrical shells under combined axial compression and bending moment. In this method, behaviour incrementally evaluated by accounting for local response each fibre element. offers computationally efficient robust scheme compute ultimate strength shells. Moreover, it enables load-shedding between buckled intact elements on compressive side, yielding failure tensile which appears ignored in existing design codes. Analyses performed with wide range parameters. Validation using finite element method demonstrates reasonably well performance proposed technique.
