Abstract

Abstract

Influences of concrete strength and steel fiber volume fraction on the ultimate bearing capacity of reinforced high-strength concrete square slabs subjected to punching shear are investigated through the experiments on six reinforced steel fiber reinforced high-strength concrete square slabs.The test results show that the deformation of slab before punching shear failure is caused by bending deformation and the steel fiber increases the ultimate bearing capacity of reinforced high-strength concrete square slabs.Finally,the formulas of ultimate bearing capacity are gotten based on the unified strength theory.
- punching shear steel fiber,
- reinforced high-strength concrete,
- ultimate bearing capacity
