Theoretical Analysis on Reinforced Concrete Bridge from Non-linear Temperature Effect

Abstract The paper presents a theoretical analysis that models the effects of temperature load induced on a two-pole, twobox reinforced concrete bridge. Implemented was theoretical analysis of thermodynamic effects, which was performed on a closed double-box reinforced concrete bridge structure. The modelling and analysis only considered the upper part of the load-bearing bridge structure. This type of bridge was selected to present the results of this study which analysed the worst effects of temperature acting on the bridge structure.
