Abstract

Summary: This study proposes analytical formulas of the temperature‐induced displacements that can be applied to general suspension bridges with any number of spans. The analytical formulas take account of the tower lateral stiffness and the elastic deformation of cables caused by the tension changes, which have not been studied in previous studies. The derived formulas are validated by the field monitoring data of the four‐span Maanshan Yangtze River Bridge. A succinct unified one‐dimensional formula is further derived for practical use. This study enables engineers to better understand the behaviour of suspension bridges and to predict the thermal deformation in a simple, generalized way.
