Abstract

Accelerated deterioration of the constituting materials is important for the long-term performance of bridges or any other load-bearing structure with several-decades-long service life. In addition to the economic consequences due to increased maintenance and repair needs, severe deterioration can lead to catastrophic collapses with possible injuries, life losses, and impairments to infrastructure systems. This chapter investigates the influence of climate change on bridge deterioration and illustrates the differences in the effects of various climate change scenarios. The considered scenarios are RCP2.6 (a low greenhouse gas (GHG) emissions scenario), RCP4.5 (a medium GHG emissions scenario), and RCP8.5 (a high emissions scenario). For... (More)

Accelerated deterioration of the constituting materials is important for the long-term performance of bridges or any other load-bearing structure with several-decades-long service life. In addition to the economic consequences due to increased maintenance and repair needs, severe deterioration can lead to catastrophic collapses with possible injuries, life losses, and impairments to infrastructure systems. This chapter investigates the influence of climate change on bridge deterioration and illustrates the differences in the effects of various climate change scenarios. The considered scenarios are RCP2.6 (a low greenhouse gas (GHG) emissions scenario), RCP4.5 (a medium GHG emissions scenario), and RCP8.5 (a high emissions scenario). For the sake of illustration, the probabilities of corrosion initiation and damage are evaluated for a simply supported beam exposed to chloride-induced corrosion in different counties in Sweden under consideration of these three scenarios as well as the historical climate conditions. The impact of climate change on the probabilities of corrosion initiation and damage is found to be higher for higher emission scenarios and to have an increasing trend from south to north.
