Abstract
Shear transfer across a definite interface must frequently be considered in the design of precast concrete connections. As the following various resistances in the effecting shear transfer strength are given : (1) Dowel action of joint steel bars, (2) Shear-key resistance, (3) Friction with axial force, (4) Adherence on the concrete surface. The purpose of this paper is to reveal the compound effects of the various resistance elements. Basic experiments on the interface shear transfer at the precast concrete connections ware carried out. Fifteen panel type specimens with the same dimensions were tested. As a conclusion, the relation of the shear transfer mechanism and shear displacement behaviour in concrete connection is clarified. And the evaluation equation of the shear transfer strength with consideration to the shear displacement conformity is proposed.
