Stress acting on deformed bars and concrete used for lifting and foundation of a - 14-m quaywall slit caisson was measured at Hakodate Port, to determine the characteristics of inequality coefficient and current states of stress distribution for lifting bars. At the same time, structural analysis of the caisson at the time of lifting was conducted using a threedimensional FEM model. The stress distribution properties of the lifting bars and caisson members were then examined. Strength of each part of the caisson was verified and design methods of reinforcing bars were also examined.
