Estudo comparativo de métodos aplicados na análise estrutural de piscinas de concreto armado.

Abstract

Swimming pools (buried reservoirs) are structural elements present in most buildings and have, among others, the purpose of storing water for leisure. Because its components are surface elements subject to loads transverse to their average plane, the structural analysis of this type of element falls on partial differential equations whose closed analytical solution does not exist for many cases. Given the complexity of the problem, it becomes It is necessary to use simplified methods in its analysis, such as the Isolated Plate method and the Plane Frames Method, and/or numerical methods, such as the Finite Element Method and Grid Analogy. For this reason, there are several structural models with different levels of representativeness and coverage, and the efficiency of each one will depend on the characteristics of the problem analyzed. This work is, therefore, a study comparison of approximate methods for the analysis of buried reservoirs, having as reference a finite element model conceived in SAP2000. The results indicated that the moments conceived by the Finite Element Method proved to be more conservative than Simplified Methods, therefore, more safety-friendly.
