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