摘要: Presents a study of shear transfer in reinforced concrete, that is, the across plane, such as at interface between precast beam and cast-in-place slab. Thirty-eight pushoff specimens were tested, some with, without pre-existing crack along plane. The shear-friction theory was found to give conservative estimate strength initially cracked concrete. A method is presented for calculation uncracked based on Zia envelope Mohr circles representing failure conditions
