Abstract
The rigidity of steel sheet-pile wall depends mainly upon the degree of connection between each pile and surrounding soil conditions. In order to obtain the section rigidity as a wall, loading tests on jointed steel sheet-piles were carried out. From the tests, following results were obtained:
(1) The force mobilized at each joint can be considered to consist of cohesive force due to connection of each pile and friction type of force.
(2) Section modulus of the wall in soft ground decreases with increase of the stress level.
(3) Both moment of inertia and section modulus of the wall obtained were nearly 30% larger than those of the unit steel sheet-pile.
