Abstract

Abstract

The influence of concentrated load position,concrete strength and FRP bars ratio on punching performance of two-way slabs were investigated by the test of 7 concrete two-way slabs reinforced with FRP bars subjected to punching shear loading.The test results showed that concentrated load position,concrete strength and FRP bars ratio were the main factors influencing the punching shear performance of concrete two-way slabs reinforced with FRP bars.Along with the increase of concrete strength and FRP bars ratio,the strain of concrete and FRP bars decreased gradually in same loading level,but the increase rate expedited gradually after cracking.The influence of concrete strength on the cracking load and the ultimate punching capacity of the test slabs was larger than FRP bars ratio.The concrete two-way slabs reinforced with FRP bars under concentrated loading exhibited brittle local punching failure.
