The sectional properties of U-type steel sheet piles as wall are 1.1-4.0 times greater than that of unit sheet pile, therefore it makes possible an economical design of sheet pile structures, in case the shearing resistance force of interlocking joints is fully expected. In order to clarify the correlation between the shearing resistance force and the sectional properties, theoretical analyses have been conducted using parameter τx.
As results, it is summarized that the section modulus as wall is applicable to U-type steel sheet piles, in case piles are driven into medium sand, however it should be reduced to 90% in the case of loose sand even if coping concrete is placed on top of sheet piles.
