in the recent years the constructions of large span reinforced concrete structures are common. The reinforced structures consist of reinforcement. Usually the lengths of the bars are of 12 m. In the construction of large span structure the length of the bars will be insufficient; to overcome this problem lapping of bars is essential. Efforts are being made to investigate the importance of lapping in the structures. Many researchers have conducted many experiments and studied the behaviour of lapped structural members.
In the present study a new type of reinforcement arrangements are made to study the flexural strength of reinforced beams. The tests conducted on the specimens are in accordance with Indian standard code. The tests are conducted on the three specimens and this study intends to test the beams made with no lapping, 100% lapping and hook reinforcement respectively. The beams are of size 1800 mm in length and the cross sectional dimension of the beams are 150mm × 200mm. The load and deflection of above mentioned beams are studied and the flexural strength of the above mentioned beams are discussed
