Abstract

The purpose of this study is to analyze the reinforced rectangular concrete short column using the Finite Element method and compare the results with excremental test results to find the percentage error in the calculation, which will help to develop the mathematical model for the different slenderness ratio of the columns. The study of eighteen columns is presented in this paper. From the literature survey, it is found that the traditional reinforcement which is used in the form of lateral ties is not sufficient in case of lateral force due to earthquakes or even if the column is loaded with a high magnitude of compressive force, it is observed that the failure of the column occurs as the ties do not prevent the bucking of longitudinal bars. Hence, there is a need for confinement reinforcement in the column to improve strength and ductility as well as increase the resistance against the lateral forces. The study of rectangular columns was focused as it has a wide practical scope as compared to square and circular columns. In this paper, a study of 18 models of rectangular columns were presented with different values of slenderness ratio ranging from 3.67 to 7. The axial compressive strength of the column is compared with the closely spaced stirrups, welded wire mesh, chicken wire mesh, stapled stirrups, and diagonal stirrups. The comparative study of axial compressive strength, vertical and lateral deformation for different slenderness shows that the Finite Element Method (FEM) results are comparable with excremental values.
