The connection in precast concrete structure shares the important role for transfer of shear acting along the interfaces. The shear transfer capacity of connection is affected on shear elements such as joint concrete, connecting reinforcement and shear key. Also, it is greatly subjected to connection width formed between two precast units. However, there exist little the monographers which discussed on effect of the width in a precast concrete structure connection on shear transfer capacity. Herein, the direct shear test was performed for the purpose of investigating the contribution of connection width to shear transfer capacity. On the basis of test results obtained, the shear transfer capacity of connection was evaluated by using a compressive strut model. It was found that the theoretical results might estimate well the test ones.
