The Analysis of Thermal Effect on Concrete Box Girder Bridge
Abstract 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 analyzed real measured cross-section temperature gradient at European bridges.
