Mechanical Behavior of Steel-Encased Concrete Filled Prefabricated FRP Tubes Short Column under Axial Compression Based on ABAQUS

Abstract:

The paper presents numerical analysis on steel-encased concrete filled prefabricated FRP (fiber reinforced polymer) tubes short column through the finite element analysis software ABAQUS and verifies simulation results compared with experimental results in order to investigate the mechanical behavior of the composite column under axial compression. Based on the correct simulation results, the full-range study combined with the concrete, steel and FRP tubes of stress distribution, the mechanical performance of the column are studied in this paper. The research shows that the stress-displacement of composite column calculated in the paper can be divided into three stages, namely, elastic stage, elastic-plastic stage and failure stage.
