Study on the Behaviour of High Strength Concrete Beam under Combined Bending and Torsion with and without Hybrid Fibres

The reinforced concrete structural elements such as the peripheral beams in each floor of multi storied buildings, ring beams at the bottom of circular tanks, edge beams of shell roofs, the beams supporting canopy slabs and the helical staircases are subjected to significant torsional loading in addition to flexure. So it becomes necessary to investigate the behaviour of beam under combined bending and torsion in an experimental way. In this project high strength beams will be subjected to combined bending and torsion. In addition to that hybrid fibres are added to the concrete and subjected to combined bending and torsion. The behaviour of reinforced beams under combined bending and torsion with and without hybrid fibre are investigated.
