Abstract
In structure construction of the tide embankment, authors are considering the structure for connecting a steel pipe pile to a steel footing for the purpose of simplifying of the structure and rationalization of construction. We propose the socket type joint in a pile head joint that is inserted the plug member extended from a steel footing in a steel pipe pile head and is integrated by filling concrete. The socket type joint is common to equip shear connectors at the connection. However, we are trying to omit the shear connector and considering making better the composite effect of the steel pipe piles and concrete by increasing the insertion length. In this study, the cyclic loading tests were carried out for specimens simulating this joint.
