Abstract:	The punching-shear strength of slabs reinforced with FRP bars without transverse reinforcement is a complex phenomenon. The main difference with the conventional reinforced concrete is that the passive reinforcement has a linear elastic behaviour up to failure. In this paper, a comparative analysis of the reliability of the existing formulations to evaluate the punching strength of FRP RC slabs without transverse reinforcement is performed through an assembled database of 88 existing tests. In addition, a preliminary proposal based on the multiaction shear capacity model has been made and its reliability has also been evaluated by means of the assembled database.
