This paper deals with the statical behavior of elastic cables used in cable-stayed structures, focusing on thermal effects. Starting from a catenary-based approach, cable’s length variation with respect to reference configuration is evaluated by superimposing a uniform distribution of temperature to standard elastic contributions. The influence of temperature variations on the mechanical behavior of elastic stay cables is highlighted through the example of the Rades La Goulette cable-stayed bridge built recently in Tunisia, confirming the soundness and the effectiveness of the proposed approach.

Abstract
This paper deals with the statical behavior of elastic cables used in cable-stayed structures, focusing on thermal effects. Starting from a catenary-based approach, cable’s length variation with respect to reference configuration is evaluated by superimposing a uniform distribution of temperature to standard elastic contributions. The influence of temperature variations on the mechanical behavior of elastic stay cables is highlighted through the example of the Rades La Goulette cable-stayed bridge built recently in Tunisia, confirming the soundness and the effectiveness of the proposed approach.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
