Abstract

The main cables are key complements of the suspension bridge. The temperature properties of main cables have significant effects on the structural responses of entire bridge. This paper presents a numerical method for temperature analysis of main cable for suspension bridge. The finite element (FE) model of main cable section is developed as homogeneous material using Plan elements. The material parameters for thermal analysis are determined based on equivalent principle. The third type thermal boundary conditions of a sunny day are calculated and then applied on the FE model for transient thermal analysis. The numerical results are compared with the experimental measurements of a full scale main cable for validation of the thermal analysis method. The results present good agreement with respect to the measurements. The temperature variations exactly explicate the changes of environmental conditions such as solar radiation and ambient temperature of daily. This FE model-based thermal analysis can provide a high effective and precision method for analysis of temperature and induced structural responses of main cables and suspension bridge.
