This paper investigates the load capacity and failure modes of slender hollow RC column under axial and eccentric loads. For the slender hollow columns, different load eccentricities and hole shapes are used. The finite element software ABAQUS is used to model and analyze the columns. The experimental test result is used to conduct a verification investigation of the nonlinear finite element modeling. All specifications of the experimentally tested columns are taken into consideration in the modeling to establish the verification of the model. When the modeling and test results are compared, it is noticeable that they are in good agreement. As a result, the modeling’s accuracy is proved. Then, a parametric study included different slenderness ratio, section shape, concrete strength and SFR strengthened has been done with the same modeling method. The effects of these variables on the column load capacity are investigated. It is found that increasing slenderness ratio led to smaller peak load. Increasing of moment of inertia of square and circular section decreased the peak load capacity. The maximum bearing capacity increased with higher concrete strength. Also, SFR distribution through the length of columns effected on load bearing capacity.
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.
