The Failure Mode and Anti-Crack Performance of the Steel Fiber Reinforced High Strength Concrete Four-Pile Cap
Based on the experiments on 4 specimens with the dimension of 700mm×700mm and different thickness, the failure mode and anti-crack performance of the steel fiber reinforced high strength concrete four-pile cap was studied. The results show that the steel fiber mixed in high strength concrete in four-pile cap enhances its cracking load, limits the propagation of crack obviously and raises the ductility greatly. It also indicates that the ultimate load-carrying capacity of four-pile cap can be improved significantly with the increase of effective thickness.
