Theoretical Manual for Analysis of Arch Dams

Abstract : This manual is intended to provide a theoretical background for the linear structural analysis of concrete arch dams. It is also designed to describe analytical procedures employed in the computer program, Graphics-Based Dam Analysis Program (GDAP)(Ghanaat 1993), and to provide an overview of the trial load method of arch dam design and analysis. The manual contains an overview and discussion of the general aspects of the finite element procedures, including system idealization, isoparametric element formulation, and solution techniques for the static and dynamic analyses of arch dams used in the computer program GDAP. This manual primarily deals with the linear-elastic methods of analyses under which a linear behavior is assumed for the concrete dam, impounded water, and foundation rock
