Transcript of SACS Brochure
Engineering Dynamics, Inc. has developed the SACS® system of software for both offshore structuresand general civil engineering applications. SACS® consists of several compatible structural analysis pro-grams which are interfaced to each other to eliminate the requirement, but not the ability, for user interac-tion with the output of one program before input to another. All programs include a full complement ofstandard engineering defaults in both English and Metric units to simplify input. The relationships amongthe programs comprising the system are schematically illustrated in the flow diagram below. All structur-al data: geometry, member dimensions, material properties and environmental conditions are generatedby the input generating programs and reside in the common input file. The solution programs operate onthis data and produce the common solution file which contains joint displacements and element internalforces. The post processing programs, using this information, evaluate the performance of the structurewith respect to any of several structural codes. Any structure not satisfying the code may be automaticallyredesigned. Additionally, plots of the structural geometry, deformed shapes and code checking informa-tion are available. Finally, complete dimensioned structural drawings, bills of materials and lofting dataare automatically produced.
