Deformation Behavior of Concrete Two-Way Slabs Reinforced with BFRP Bars Subjected to Eccentric Loading

摘要

Based on the punching shear test results of 9 simply supported concrete two-way slabs reinforced with basalt fiber reinforced polymer (BFRP) bars subjected to eccentric concentrated loading, the deflection distribution and the load-deflection characteristics of test slabs are investigated. The test results show that the deforma-tions of test slabs before punching shear failure are caused by bending moments. The concrete strength, the ratio of FRP bars reinforcement, the location of concentrated load and the ratio of punching span are the main factors that affect the load-deflection curves and the energy dissipations capacity of concrete two-way slabs reinforced with FRP bars under eccentric concentrated load.
