Abstract

An experimental research is carried out on thirty specimens of steel reinforced concrete and steel fiber reinforced concrete (SFRC) two-pile thick cap of 1-5 model ratio with different concrete strength, volume ratio of steel fiber, effective thickness of cap, reinforcement steel ratio and method. On the basis of experimental records, such parameters as the crack distribution and extending, the deformation at the mid-point on the bottom of specimens and the strain of concrete and tension bearing steel bar, the main factors which affect the ultimate bearing capacity of SFRC two-pile thick cap are analyzed systematically in this paper, which provide reliable data for further research on punch strength, shear strength and calculation on steel of SFRC cap with twopile. Meanwhile an available and reasonable reference is provided for revising the norm.
