Abstract

Finite Element Modelling and analysis of rectangular concrete beams reinforced internally with Hybrid Fibre Reinforced Polymer (HFRP) reinforcements under pure torsion is carried out in this study. Different parameters like grade of concrete, beam longitudinal reinforcement ratio and transverse stirrups spicing are considered. The basic strength properties of concrete, steel and HFRP reinforcements are determined experimentally. Experimental torque verses twist relationship is established for various values of torque and twist using elastic, plastic theories of torsion. Finally the ultimate torque is determined using experimentaly for different parameters considered in this study. Based on this study, a good agreement is made between finite element analysis and the experimental behaviour.
