Estudio mecánico a colapso en grandes tuberías de abastecimiento de agua potable

Abstract

The Polytechnic University of Valencia works together with EMIMET through a research agreement, whose objective is to perform the mechanical calculation of new buried pipes collapsing for the supply of drinkable water. The objective is to determine the minimum thickness of the steel pipes to be installed buried, as well as the working and service limit conditions. The mechanical behaviour and collapse of pipes with and without traffic loads and inside a sheath is studied. The calculations have been made through mathematical finite element modeling (MEF) and the calculation of the critical pressure using the equations of the American Water Works Association. The results obtained have been the stresses, deformations, safety coefficients and minimum thicknesses of the pipes.
