COMPUTATION OF LOADS ACTING ON THE CROSS-STRUCTURE AND STRUTS OF TWIN HULL SHIPS IN BEAM WAVES

This report describes a FORTRAN computer program which provides the transverse bending moment, sideload, and vertical shear force acting on the crossbeam structure and/or struts of twin hull ships in beam waves. The computer program is based upon a two-dimensional potential flow model which includes the effects of the wave diffraction and body motion. Program structure is outlined, and instructions are provided for preparing input data and interpreting output results. (Author)
