The present study investigates the behavior of concrete specimens confined with woven roving glass fabrics under uniaxial compression. The fabric made up of 360G.S.M. woven roved E-glass is embedded in a polyester resin before application. Experimental investigations have been carried out on confined and unconfined concrete specimens of size 150 mm (diameter) X 300 mm (height) under a displacement controlled loading. The effect of number of layers on confinement has also been investigated. Load versus deflection plots have been obtained for all the specimens. Numerical studies have been performed on the confinement effect of the wrapped concrete specimens. A non-linear finite element analysis has been conducted by developing numerical models in a general purpose finite element commercial software ABAQUS. The results obtained by numerical study have been compared and validated with the corresponding experimental results. Parametric studies have been conducted to study the effect of confinement on the response of the specimens. The parameters affecting the confinement were found to be the grade of concrete and number of layers of the fabric. Further, mesh sensitivity analysis has also been carried out to find out the mesh dependency of the confined specimens and results have been presented.
