Finite element simulations of the shear capacity of GFRP-reinforced concrete short beams

摘要

This paper presents a numerical investigation of the shear behavior of short concrete beams reinforced with glass fiber reinforced polymer (GFRP) for flexure and without shear reinforcement. A nonlinear finite element (FE) model is developed using the commercial software package ABAQUS to simulate the shear behavior of deep beams subjected to four-point loadings. The proposed FE results including the shear capacity and failure mode are verified and compared with previously published experiments [1]. The main purpose of the present FE model is to extend the numerical analysis and conduct a parametric study in the future. The present numerical analysis consisted of 5 short beams subjected to four point bending until failure. The effects of the shear span to depth ratio (a/d) and flexural reinforcement ratio on the ultimate shear capacity and mode of failure are investigated.
