Abstract

An analytical study is done to evaluate the capacity enhancement of axially loaded short columns that are confined with Fiber Reinforced Polymer (FRP) fabric. Finite Element Method using ANSYS 12 is utilized to simulate reinforced concrete columns specimens and their confinement layers of the FRP material. First, the model is compared with results obtained from previously experimental published work and also from well-known mathematical equations to verify the validity of the employed model. Then a parametric study is performed through analysis of 104 models. The varying parameters are: the column cross section, the number of confinement layers (plies), the radius of the rounded corner, the column height, and the strength of the concrete material. The deflection, the cracks pattern, the stresses and the strains of loaded specimens are calculated and evaluated. It is concluded that the strength and ductility of columns are increased after confinement with FRP material. In addition, the properties of the confined columns are significant enhanced by increasing the corner radius to width ratio (2r/b). Also the increase of the number of plies increases the axial compressive strength of confined columns.
