SMArt Crossing is a method of overpass construction that uses an on-site structure to place a joint between a steel pile head and a steel pier. It enables completion of the construction work in a short period of time by eliminating the process of making concrete footing. The connection is a composite structure of steel frame and concrete filled inside the frame. The static loading tests were carried out in order to investigate the failure mechanism and the ultimate strength of the connection. Performance of the connection was examined by changing such details as shear connector, filling-concrete, etc. As a result, it was confirmed that by using the calculation proposed in this report the ultimate strength of the connection was enough for practical application and that the shear connector was not required in steel shell of the composite connection.
