| Abstract: | Proper hybrid distribution of steel bars and GFRP bars can improve the durability of concrete structures in significantly,thus it is an excellent reinforcement format.Flexural capacities of eight hybrid reinforced concrete beams are tested.Based on the test results,the characteristics of crack and load-deflection relation of hybrid reinforced concrete beam are studied and a method is suggested for calculating the crack width and deflection of the hybrid reinforced concrete beam. |
