Abstract

The effect of structural changes on the temperature behavior of a long-span bridge pylon was examined using field-measured data and finite element (FE) analysis. Temperature behavior of the pylon could be modeled using two characteristic parameters, α and β, which reflect the influence of the variation in the ambient temperature and the sectional temperature difference, respectively. Two major structural changes namely, decrease in stiffness in the lower region of the pylon and decrease in area of the main cable were considered in the FE analyses, which showed that both α and β were affected by the structural changes. Furthermore, the two characteristic parameters could be extracted with sufficient accuracy from field-measured temperatures and tilting angle data using a system-identification technique. Consequently, the feasibility of identification of structural changes by continuous observation of temperature parameters was demonstrated. However, the tilting angle of the pylon is influenced by other loads than the temperature and therefore future studies on eliminating other loading effects (such as that owing to wind or traffic) are necessary.
