Temperature Field and Gradient Effect of a Steel-Concrete Composite Box Girder Bridge
Advances in Materials Science and Engineering, 2021 To study the effect of the temperature field and gradient of a steel-concrete composite box girder bridge, a 5 × 35 continuous composite box girder bridge is used as the research object. The temperature measuring point is set by selecting a typical cross

The measurement of thermal changes on concrete box girder bridge [PDF]
MATEC Web of Conferences, 2016 Thermal load, especially vertical temperature gradient is an important factor that should be considered during the bridge design procedure. In the world several researches focusing on thermal influences was performed, mostly in USA and China, but only a few analysed real measured cross-section temperature gradient at European bridges.
