Flexural Behavior of Void Reinforced Concrete Slab with CFRP Reinforcing Bars

摘要：

　　Use of hollow material in slab can reduce self-weight and deflection than solid slab with CFRP reinforcement.This study was intended to evaluate the bending performance of void flexural members with CFRP reinforcements by bending tests.Test results showed that specimens with void and solid section had the similar failure mode by concrete crushing at the compression zone,and that there was a big flexural capacity difference between the two section.Flexural capacity of solid section with CFRP bars was increased by 55% for void section.Thus,for the design offlexural members with CFRP bars by concrete crushing failure,it is important to calculate the exact distribution of strains and stresses,and to consider the reduction of flexural strength of void section.
