Abstract: The Arch Dam Stress Analysis System (ADSAS) is a computerized version of the trial load method of analyzing arch dams. ADSAS assumes linear elastic behavior for the entire dam, i.e. the dam is assumed to support the computed tensile stresses within the concrete mass and across the monolith joints without cracking or opening the joints. Although the trial load method is not considered to be as accurate as the finite element method, ADSAS can produce results that compare favorably with those of the finite element analysis with a properly defined mesh. For dams that fit the ADSAS format, input can be taken directly from the layout drawings, and changes or modifications to the dam layout can be made a minimum of changes to the input file. Thus, ADSAS is a logical choice for performing a preliminary stress analysis during the layout process. This user’s guide for ADSAS describes general requirements for the input file, provides guidance on modeling techniques, and cites some special layout capabilities. It gives detailed descriptions of the data required for each of the input cards, which are an integral part of ADSAS. Some guidance in interpreting the data output is given. Appendixes include sample files and error messages.
