Hat-shaped steel sheet pile design method and hat-shaped steel sheet pile manufacturing method

摘要

A hat-shaped steel sheet pile 1 which is arranged in a plurality and is arranged in the longitudinal direction, and has a cross-sectional area A (cm 2 / m) per 1 m in the width direction of the hat-shaped steel sheet pile 1 and a hat. The relationship between the section moment of inertia I (cm4 / m) around the section centroid line M extending in the width direction in a plan view viewed from the longitudinal direction of the shaped steel sheet pile 1 satisfies the formula (1), and in the plan view The distance between the first intersection P1 of the extension line of each of the pair of flange portions 11 and the cross-section centroid line M is D1 (mm), and the second intersection point of the cross-section centroid line M in each of the pair of flange portions 11 When the distance between P2 is D2 (mm), Formula (2A) and Formula (2B), Formula (3A) and Formula (3B), Formula (4A) and Formula (4B), or Formula (5A) And the expression (5B) is satisfied.
