Research of long-span bridge and traffic system subjected to winds: A system and multi-hazard perspective

Abstract

Wind effects on long-span bridges and moving vehicles have drawn considerable attention during the past years. Effectively considering the dynamic interactions between wind, vehicles and bridges and rationally assessing the bridge performance becomes essential to this type of critical infrastructure system. The impact of strong winds on long-span bridge transportation systems has received a lot of attention during the past decades. Meanwhile, low to moderate winds may serve as a type of important service load acting on the long-span bridge transportation system, along with other extreme or hazardous loads. In addition to the structural integrity, it is also important to appropriately assess the vehicle performance, such as safety and comforting issues, under wind so that the associated risks can be identified and mitigated. This paper summarizes some recent advances on the research of wind effects on long-span bridge and traffic systems with a focus on the efforts from a system and multi-hazard perspective.
