| Abstract: | It is introduced in this paper that laboratory flexural tests are carried out using concrete slabs reinforced with GFRP bars and steel bars. Based on tests results, the deformation process of specimens under load is described. Comparison and analysis are made between cracking and ultimate load, deflection and strain of concrete of the two slab types. In addition, concrete slabs with different GFRP reinforcement ratio are tested by FEM simulation. Effect of GFRP reinforcement ratio to the rigidity of slab is discussed. Prediction equation of flexural rigidity is suggested. This equation is acceptable for concrete slabs reinforced with GFRP bars after cracking. |
| Keywords: | GFRP bar Flexural test Reinforcement ratio FEM simulation Flexural rigidity |
