The object of present paper is to make clear the structural performance of precast concrete beam with topping concrete, and the shear transfer mechanism as well as behavior of slip displacement at the interface of lateral and horizontal connections for three kinds of anchorage method by U and L shaped reinforcement as well as steel plate. The experimental researches were carried out for three series of test specimens associated with the flexural test of beam and the direct shear test of connections. The results mainly obtained are as follows; The test specimens of beam possessed a full anchorage performance for three kinds of anchorage method. Furthermore, it was verified from test results that the ultimate shear strength in the connections of precast concrete beam can be estimated by a proposed formula for design.
