Abstract

A new method for analysis of hydraulic structures supposing their simulation in the form of prismatic systems is proposed. Algorithm and computing system effectiveness is provided by smaller - in comparison with digital methods - equations resolution order and high accuracy of results. The main part of paper is devoted to development of algorithm of automated formation of geometric structure, edge conditions as well as of equilibrium equations and equations of strain compatibility in nodal lines of complex structure with free cinfiguration. Algorithm of equations formulation is based on solution of differential equations of plate equilibrium through Fourier series transformation and start conditions use resulting in formation of resolving system of algebraic equations where initial parameters and final values of forces are defined. The example of structural analysis of Volzhskaya hydroelectric station building during different work modes is given.
