Influence of Load Conditions on Mechanical Behaviors of Steel Tubular Columns Filled with Steel-Reinforced Concrete Subjected to Axial Load

Abstract:

By using the finite element software ADINA, the focus of the paper is about the influence of load conditions on the axial compression performance of steel tubular columns filled with steel-reinforced concrete (STSRC) with the base that the calculated results are confirmed by the experimental data. Three types of loading conditions are these that: 1. Steel pipe, steel placed in the steel tube and concrete bear the compressive load; 2. Compressive load acts on the steel and concrete and there is a good bonding between the steel and concrete; 3.The steel and concrete bear the axial load, but the bond-slip between the steel tube and concrete are considered. The results show that the calculated results based on ADINA and the experimental ones are in agreement well, the bearing capacity and the ductility of the short composite columns are not almost influenced by the load condition-one and load condition-two, while the load condition-three has a influence on the axial compression performance of STSRC.
