Description of material properties of hardening concrete inside deck of composite bridge
I. Monzón Hualde, P. Štemberk, O. Lojkásek
pages 120 - +9p., full text

During execution, concrete bridges are represented by several varying structural systems. In order to reduce the effect of the system variation, the execution of concrete bridges requires special procedures, when the construction equipment needs to be placed, or ride on the concrete, which did not reach its design properties. This paper shows an analysis of a concrete bridge deck. For the analysis, the material parameters of concrete are approximated by functions, which take into account the effect of composition and local temperature. A simple thermal analysis is used to express the thermal field distribution in the concrete deck which affects the progressing hardening. Finally, a mechanical analysis is conducted which gives the possible deformation of the bridge deck caused by a mobile concrete pump and other equipment.
