Finite element analysis of hollow beams strengthed with frp wrapping

Abstract

In recent years, the structural applications of hollow core beams became widespread because of its advantages such as high strength, large energy absorption capacity, light weight, adequate ductility and concrete saving. The main objective of this study is to analyse the performance of reinforced hollow core beams strengthened with CFRP (Carbon Fibre Reinforced Polymer) wrapping. Experimental results revealed that the confinement of CFRP wrapping significantly enhanced the load carrying capacity, stiffness of hollow core beams. Numerical models were developed with the help of ANSYS software to validate the behaviour of hollow beams with CFRP wrapping.
