Overall assessment of the structural performance of buildings requires accurate modeling and better understanding of axial and lateral load response of columns. This paper focuses on modeling of columns with insufficient transverse reinforcement and poor reinforcement details. They are likely to experience brittle shear failure and lose their axial load carrying capacity under large lateral loads. A macro model procedure is developed to predict the strength and displacement capacity of the columns before and after shear failure and at axial load failure. The model is being implemented and validated in the OpenSees software. The model is applied to estimate the lateral loaddeformation response of previously tested columns, and the predicted and experimental data are then compared. The model considers total lateral deformation of the column to be composed of three deformation components due to flexure, shear and reinforcement slip. In the proposed model, lateral load-deformation response of the column is simulated by estimating flexural and shear deformation components separately while considering their interaction when they are combined.
