Simple analysis of arch dams
Higher safety, and sometimes even cost benefits, can be obtained through the use of well-proportioned arched dams in comparison with other types. However, design analysis of different shape alternatives, especially in the preliminary stages, for the arch dam is usually considered to be complex, costly and time consuming. With the aim of offering a simple, user-friendly numerical design tool for arch dams, this paper presents a modified version of the Ritter crown adjustment. The basic new idea consists in adopting stress type, instead of displacement type, degrees of freedom - average hoop stresses in the horizontal elements (arches) and flexural stresses in the vertical element (crown cantilever) - thus simplifying the equilibrium equations and leading to more meaningful primary results. The way is opened to nonlinear computations through the introduction of 'plastic hinges' in the cantilever. The structure of this design code makes for flexible, interactive use by experienced designers. Computation times are practically non-existent on a 486 PC.
