The present paper discusses on the mechanical behavior of the precast concrete members subjected to lateral cyclic loading when the new grout-filled sleeve type of connection for thread-deformed reinforcing bar with high-tensile strength was applied to their plastic hinge area. It was found from this test that a compressive strut generated in the plastic hinge area. The new approach for the model of compressive strut was derived herein. Using this model, the shear transfer capacity was represented by the sum of friction forces by tie and arch actions as well as dowel force at the interface of precast member and joint mortar layer. The results for the maximum load obtained by the test were well estimated by theory of the shear transfer capacity.
