Abstract

This paper is concerned with the detailed study on the behavior of steel tubular columns in-filled with concrete. Moment-curvature-thrust relationships are generated for column cross-sections by an iterative process. Nonlinear equilibrium equations which include geometric and material nonlinearities are solved by an incremental-iterative numerical scheme based on generalized displacement control (GDC) method. The analytical model is used to investigate the effect of various parameters that could influence the behavior and ultimate load. Column end restraints are also considered as one of the parameters. The variables selected for the study cover a wide range of parameters arising from various loading conditions and column geometries.
