Abstract: The nonlinear flutter featured by the limit cycle oscillation (LCO) is a typical aeroelastic phenomenon for bluff decks and/or streamlined decks at large incidence angles. In this study, the flutter characteristics of a ...

Abstract: Investigations on the wind loads and aerodynamic responses of the bridge girder segment during the lifting construction stage are limited. Free vibration tests of a lifting girder segment of a kilometer-span cable-stayed ...

Abstract: With the specific objective of exploring the surface pressure characteristics and further revealing the torsional vortex-induced vibration (VIV) mechanisms of a bridge deck with a particular geometry, numerous simultaneous ...

Abstract: An aerodynamic describing function (ADF)-based model for simulating the nonlinear self-excited forces on bridge decks is developed, where the ADFs can be conveniently identified using the experimentally or numerically ...

Abstract: A low-frequency continuous torsional motion technique (CTMT) is presented to efficiently extract the aerostatic force coefficients (AFCs) of bridge decks. In contrast to the conventional numerical simulations at a series ...

Abstract: Wind-resistant performance is a major concern in the design and operation of pipeline suspension bridges. The mean aerodynamic force coefficients (MAFCs) are essential parameters for quantifying the wind loads on a bridge. ...

Abstract: With the wide application of extended reach wells and horizontal wells, the geological conditions faced during the drilling process have become increasingly complicated, and the resulting wellbole collapse problem has ...
