STUDIES ON THE JOINT STRUCTURE BETWEEN FOOTING CONCRETE AND STEEL SHEET PIPE PILE WALL

Several joints between footing concrete and steel sheet pipe pile wall have been used, but their shear transfer mechanisms of the joint have not been made clear fully under present conditions. Therefore small scale and large scale model tests with some different joints including a new proposed joint are carried out, and their shear transfer mechanism has been investigated based on tests. Consequently, the proposed joint structure which has sufficient shear transfer capability and construction efficiency has been applied successfully at Katsushika Edogawa line, Metropolitan expressway in Japan.
