In the field of construction hollow sections have found wide application due to its advantageous properties. Many research works have been conducted to study the flexural and tensional behaviour of hollow reinforced concrete beams. But its behaviour using High-Performance Concrete (HPC) has been poorly noticed. In this study an attempt made to evaluate Hollow reinforced beams made with HPC and reinforced with hybrid steel fibres. The flexural behaviour of hollow beams based on the effect of Carbon fibre reinforced polymer (CFRP) has also been explored. A comparison is made between the results obtained from analysis using ANSYS software with the experimental test result. It is noticeable that the flexural strength, its ductility, and stiffness is not affected but the self-weight of the structure is reduced due to hollow beams.

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.
