Abstract
The recent construction of the NewmarketViaduct, a major 12-span, 700m long, post-tensioned highway bridge, created an excellent opportunity to evaluate in-situ performance of such structures. To that end, a structural monitoring system was installed on the bridge to measure strains, deflections, accelerations and temperatures. This study analyses more than one year's worth of temperature data. The focus of the monitoring data analysis is on finding the maximum positive and negative temperature gradients that can develop in the bridge box girder and comparing those to design code guidelines.A numerical study is also conducted to explore the effect of various design and actual gradients on girder bending moments.
