DOI: 10.1016/j.engstruct.2021.112407
Abstract: Abstract Maintenance generally enhances bridge performance. However, the collapse of the I-35Â W Highway Bridge over the Mississippi river in 2007 highlighted that maintenance work could generate adverse traffic load effects (LEs), resulting in a higher… read more here.

DOI: 10.1109/access.2018.2840333
Abstract: With emphasis on long-span bridges, the dynamic responses of bridges without considering random traffic flows were found to be different from actual situations. The introduction of a random traffic flow model provides a new approach… read more here.

DOI: 10.1177/14759217241246504
Abstract: Short/mid-span bridges are the most commonly used infrastructure in highways, railways, and other transportation projects. With service time increasing, local damage and performance degradation of short/mid-span bridges are inevitable. Therefore, the assessment of the bridge… read more here.
