The present paper treats an experimental study on in-plane shear behavior of connection for prestressed concrete hollow core slabs, where two series test specimens were manufactured with or without topping concrete in the upper part of a prestressed concrete hollow core slabs and a shear-key was simultaneously amounted on the side of a prestressed concrete hollow core slab. By the experiment results, the shear-key on the side of a prestressed concrete hollow core slabs contributed to the enhancement of plane shear strength. While, the effect of shear friction and dowel action resistances which act on the steel rod in topping concrete were investigated. Formula for shear transfer capacity was proposed considering bearing pressure capacity and shear friction capacity by using ultimate strength theory. The experimental results were compared with proposed shear transfer formula It was concluded that the formula gave a good prediction for them.
