Integrated structural analysis program for piping: ISAP-III

ISAP-III is a structural analysis and stress evaluation programs for piping and can be used for nuclear, boiler, chemical plants' piping design and others. Its advanced features are as follows: (1) Easy input by menu-type interactive method using on-line terminals. (2) Also user can select card type input whose formats are very simple and familiar with piping designers. (3) Input data generation function for NASTRAN and MARC program, so nonlinear analysis can be performed quickly only by adding special data for nonlinearity. (4) Capability of multi-support excitation analysis, various combining methods of modal responses, etc for advanced vibration and aseismic analysis and evaluation. (5) Concentrated data base system for wide extensity. (6) Stress evaluation capability in accordance with nuclear, boiler and chemical plants' codes. (author)
