Study on the Influence Factors of Bearing Capacity of the Fiber Reinforced High Strength Concrete Three-Pile Caps

Abstract:

Based on the experiments of 10 model specimens of fiber reinforced high strength concrete three-pile caps with the dimension of 831mm×831mm×831mm, the mechanical behavior and the important factors on the cracking load and ultimate bearing capacity of fiber reinforced high strength concrete three-pile caps were researched. The study indicates that with increasing of concrete strength, the volume fraction of steel fiber, the effective thickness and reinforcement ratio of pile cap, the bearing capacity of three-pile caps improves largely. At the same time the type of steel fiber and steel ratio have remarkable effects on the bearing capacity. The results are valuable for establishing bearing capacity calculation formulas of fiber reinforced high strength concrete three-pile caps and improving “the Technical Specification for fiber Reinforced Concrete Structure.”
