Paper Abstract

The Zhanjiang Bay Bridge is a cable stayed bridge with a main span of 480m. Structural behavior due to thermal effects is presented in this paper in according to data received from a health monitoring system (HMS) since 2006. Data obtained from the analysis includes temperature gradients and time lags in the steel box girder, concrete tower, and stayed cables. By comparing the measured and calculated thermal displacements, it was possible to estimate the unmeasured thermal gradient on the surface of the towers as well as to determine that one of the expansion joints was likely constrained and contributing to the bridges asymmetrical displacement.
