In constructing an offshore structure in a sea area covered with ice it is necessary to understanding the ice load exerted by drift ice. To determine the adhesive and the shearing strengths, and their relation to the bending strength, we used the first-year ice of Notoro lagoon. To define the stress distribution of shear strength of the test specimen, we employed FEM elastic stress analysis. The adhesive strength test specimen kept outdoors separated at the attached surfaces, yielding an adhesive strength of 50 kPa. The shearing strength test specimen ruptured in bending. The shearing strength was found 0.2-0.3 MPa.
