  • Construction of joint portion of semi-submerged marine structure
    Patent number: 4771720
    Abstract: The construction of a joint portion between a column and a bracing in a semi-submerged marine structure which consists of a platform, a column, a submerged body and a bracing to which the column is joined. The bracing consists of a portion having a small cross-sectional area, a tapering portion the cross-sectional area of which increases gradually toward a free end of the bracing, and a free end portion having a larger cross-sectional area. In a joint portion between the column and bracing, the portion of the bracing which has a larger cross-sectional area is in the interior of the column. If the tapering portion of the bracing is welded to the outer plate of the column, the stress in the joint portion can be dispersed into the outer plate and the same portion of the bracing.
