ABSTRACT:
In a metal sheet pile, an effective width B [mm], a flange width Bf [mm], a height H [mm] and a geometrical moment of inertia I [cm4/m] meet the inequalities 700≦B≦1,200; 280≦Bf≦0.0005×B2−0.05×B; and −0.073×B+0.0043×I+230≦H≦380. The metal sheet pile provides a better cross-sectional performance than a background art metal sheet pile.
