Bridge buffeting by skew winds: A quasi-steady case study
Wang, Jungao; Jakobsen, Jasna Bogunovic; Øiseth, Ole Andre; Snæbjørnsson, Jonas Thor (Peer reviewed; Journal article, 2022)The buffeting response of a 5000-m-long curved floating bridge is investigated for different mean wind directions, with emphasis on the wind load formulations and use of experimental data. Wind tunnel tests, with a section ... -
Bridge buffeting by skew winds: A revised theory
Morais da Costa, Bernardo; Wang, Jungao; Jakobsen, Jasna Bogunovic; Øiseth, Ole Andre; Snæbjørnsson, Jonas Thor (Peer reviewed; Journal article, 2021-01)An improved bridge buffeting theory is established with an emphasis on skew wind directions, for both turbulence- and motion-dependent forces. It provides simplifications and generalizations of previously established ... -
Data-driven prediction of mean wind turbulence from topographic data
Morais da Costa, Bernardo; Snæbjørnsson, Jonas Thor; Øiseth, Ole Andre; Wang, Jungao; Jakobsen, Jasna Bogunovic (Peer reviewed; Journal article, 2021)This study presents a data-driven model to predict mean turbulence intensities at desired generic locations, for all wind directions. The model, a multilayer perceptron, requires only information about the local topography ... -
Long-term response of a curved floating bridge to inhomogeneous wind fields
Morais da Costa, Bernardo; Wang, Jungao; Jakobsen, Jasna Bogunovic; Snæbjörnsson, Jonas Thor; Øiseth, Ole Andre (Peer reviewed; Journal article, 2023-07)A numerical model of a 5 km long curved floating bridge, planned for the Bjørnafjord, in Norway, is subjected to strong wind events with stationary mean properties that vary along the bridge axis. A Weather Research and ... -
Observations of bridge stay cable vibrations in dry and wet conditions: A case study
Daniotti, Nicolo; Jakobsen, Jasna Bogunovic; Snæbjørnsson, Jonas Thor; Cheynet, Etienne; Wang, Jungao (Peer reviewed; Journal article, 2021)The characteristics of wind- and rain-wind-induced vibrations of bridge stay cables are studied by using ambient vibrations records acquired on a cable-stayed bridge. Mean wind speed and wind-cable angle, as well as the ... -
Unfrozen Skewed Turbulence for Wind Loading on Structures
Cheynet, Etienne; Daniotti, Nicolo; Jakobsen, Jasna Bogunovic; Snæbjørnsson, Jonas Thor; Wang, Jungao (Peer reviewed; Journal article, 2022)The paper introduces an algorithm to generate a three-variate four-dimensional wind turbulence field suited for yawed wind dynamic load simulation. At large yaw angles, a relaxation of Taylor’s hypothesis of frozen turbulence ... -
Vortex-induced vibration (VIV) effects of a drilling riser due to vessel motion
Joseph, Rohan Shabu; Wang, Jungao; Ong, Muk Chen; Jakobsen, Jasna Bogunovic (Journal article; Peer reviewed, 2017)A marine riser undergoes oscillatory motion in water due to the vessel motions, known as global dynamic response. This to-and-fro motion of the riser will generate an equivalent flow that can cause Vortex-Induced Vibrations ...
