Title in Portuguese
Estudo de cabos livremente suspensos
Keywords in Portuguese
Cabos - estruturas
Coberturas pênseis
Abstract in Portuguese
Modernamente os cabos vêm sendo empregados como elemento portante de coberturas de grandes vãos - as coberturas pênseis. É finalidade deste trabalho a apresentação da análise estática de cabos livremente suspensos, visando à sua aplicação nestas coberturas. Realiza-se o estudo de cabos - submetidos a carregamento estático uniformemente distribuído em todo o seu vão, a variações de temperatura e a deslocamentos de seus apoios - através do Processo Analítico (equações diferenciais) e do Processo dos Deslocamentos (rigidez tangente). Considera-se a não linearidade geométrica e admite-se a linearidade física. A comparação e análise dos resultados destes processos de cálculo são feitas através de experimentação numérica.

Abstract in English
Nowadays cables have been utilized as a resistant element in roofs of large dimensions, the hanging roofs. The objective of this work is to present the static analysis of suspended cables, aiming their application in roofs. A study of cables subjected to static uniform load distributed on the length, variations of temperature and displacements of the supports is done through Analytical Process (differential equations) and Stiffness Process (tangent stiffness). Geometrical non-linear analysis is allowed and physical linear analysis is admitted. The results are compared and analysed through numerical experimentation.
