The Structural Synthesis Design Program (SSDP) described herein is an extension of the original MIDSHIP section program developed at the Center. The 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 developed by it 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 have been provided to aid the program user in preparing input data. These examples are of no specific existing ship type. They are merely idealized examples intended to illustrate the design capabilities of the program. The English unit system is used in the program. No attempt has been made to convert to metric units since at this time the majority of section designs are still done with English units.
