Abstract
A rapid construction method of overpasses has been proposed, which features on-site joint between one foundation steel pile and one steel pier in short time. The joint utilizes steel-concrete composite connection to absorb placement error of piling without making concrete footing. 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, filled-concrete, and so on. As a result, it was confirmed that the shear connector was not required in steel shell of the composite connection and that the ultimate strength of the connection was enough for practical application.
