A new steel sheet pile of wide hat-type was developed. Advantage of using wide type of sheet pile is reducing steel weight and consequently cutting down construction cost. Field driveability tests were conducted in order to verifying vibro-driveability of wide hat-type sheet pile. As a result of the tests, penetration rates of newly developed sheet piles were less than those of U-type sheet piles. Axial stresses developed in sheet pile during driving were fur less than yield stress of sheet pile. Futhermore, initial penetration rates of sheet piles were much larger than those obtained from WEAP program.
