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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
