Ahmed, Khondaker S.; Chuan, Max T. W.; Dai, Jian; Kok Keng, Ang (Journal article, 2022)Padma Multipurpose Bridge (PMB) is one of the most important projects in the history of Bangladesh due to its regional importance, economic benefit, and primary connectivity of one-third population of the country. The ... -
Effect of modelling inhomogeneous wave conditions on structural responses of a very long floating bridge
Dai, Jian; Stefanakos, Christos; Leira, Bernt Johan; Alsos, Hagbart Skage (Journal of Marine Science and Engineering;volume 9, issue 5, Peer reviewed; Journal article, 2021-05-19)Floating bridges are suitable for connecting land parcels separated by wide and deep waterbodies. However, when the span of the crossing becomes very long, the water environment exhibits inhomogeneities which introduce ... -
Effect of wave-current interaction on a long fjord-crossing floating pontoon bridge
Dai, Jian; Abrahamsen, Bjørn Christian; Hansen Viuff, Thomas; Leira, Bernt Johan (Engineering structures;Volume 266, 1 September 2022, 114549, Peer reviewed; Journal article, 2022-06-20)Fjord-crossing floating bridges are sophisticated structures subjected to complex environmental loadings including combined action of wave and current. However, the effect of wave-current action is often neglected in a ... -
