- Abstract
- Thermal actions have a signicant eect on bridge structures and can at some sections account for more than 20% of the reinforcement. Such actions are especially important in certain types of concrete bridges, e.g. portal frame bridges. Thermal actions dier from other load types considered during bridge design through being a constraining load. A temperature prole can be divided into a uniform part that aect the bridge with a
linear expansion and a non-uniform part that will induce an arch shape of the bridge deck. Using the current building code, thermal actions can account for more than 20% of the total demand of reinforcement at midsection making them so large that they cannot be neglected. This makes thermal actions in bridge design... (More) - Thermal actions have a signicant eect on bridge structures and can at some sections account for more than 20% of the reinforcement.
