This paper evaluates the shear behaviour of simply supported normal-weight and lightweight concrete slabs reinforced with glass fibre reinforced polymer (GFRP) rebars and subjected to four-point static loading.Atotal of seven concrete slabs of 2.8m long, 1.0mwide and 0.18mdeep,were constructed and tested.Different parameters like type of concrete (normal – and lightweight), reinforcement ratio, reinforcement configuration and the existence of top reinforcement are considered in order to assess their influence on static behaviour and shear strength of concrete slabs. Furthermore several codes and theoretical models applied for predicting shear strength of concrete members reinforced with GFRP rebars have been compared with test results, and the discrepancies and compatibilities have been established and discussed. The lack of code models to predict accurately shear strength of LWconcrete slabs reinforced with GFRP has been revealed.
