Cracking Due to Thermal Effects on Bridges
The thermal effects on bridges, with regard to the crack development and imposed deformations can, if not treated carefully by either computational and/or constructional means, result in considerable damage to the structure. Some bridges constructed in the last two or three decades show examples of this undesired effect, but nevertheless the few cases published are only the peak of an iceberg of numerous cases of damage, sometimes in connection with other effects, which can be linked to the thermal influence on bridges. See Fig. 1, which shows the damaged web of the Jagst Bridge in Germany.
