Abstract
The Structural Synthesis Design Program (ssdp) is an extension of the original MIDSHIP section program developed at this Center. SSDP may be used to design the longitudinal scantlings for a variety of ship cross sections, consisting of any practical combinations of decks, platforms, bulkheads, and materials--steels and/or aluminum. The final section design will have the lowest practical weight for the chosen geometric configuration and imposed loadings. The scantlings it develops will comply with design criteria defined by current U. S. Navy design practices. An additional feature of SSDP is that the program can also be used to perform a design validation of proposed section design. The input data required for operating the program are no more comprehensive than those normally assembled to develop an efficient design of a cross section by manual methods. Four demonstration problems are provided to aid the program user in preparing input data. These examples are of no specific existing ship type but are idealized examples intended to illustrate the design capabilities of the program.
