Title in Portuguese
Determinação das forças em cabos tensionados a partir de ensaios de vibrações livres.
Keywords in Portuguese
Cabos
Dinâmica
Vibração
Abstract in Portuguese
Neste trabalho são apresentados os aspectos mais relevantes do comportamento dos cabos, a descrição dos comportamentos estático e dinâmicos e aplicação da análise dinâmica na determinação da força de um cabo a partir de ensaios de vibração livre. Serão analisados dois estudos de caso onde esse método foi aplicado : nos tirantes da cobertura do estádio Castelão em Fortaleza e nos estais da ponte sobre o rio Sergipe. Em seguida serão discutidas as vantagens e limitações do método.

Abstract in English
In this work the most important characteristics of the cables are presented: their static and dynamic behavior and the vibration method to evaluate the cable force from free vibration tests results. Two study cases are described: the cables of the Castelao Stadium at Fortaleza and the stays of the bridge over Sergipe river. The advantages and limitations of this method are discussed.
