Role of Indicial Functions in Buffeting Analysis of Bridges
Publisher: American Society of Civil Engineers
Abstract: The problem of the wind buffeting of bluff bodies, in this instance bridge decks, is reexamined in the present paper from the standpoint of linearized theory. The links of flutter derivatives to aerodynamic indicial functions ...
Amplitude and Turbulence Effects on Bridge Flutter Derivatives
Publisher: American Society of Civil Engineers
Abstract: The paper refers to established theory for the flutter of long-span bridges. Within that theory it is shown that the assumption of a spanwise diminution of coherence in the flutter derivatives can account for the observed ...
Aeroelastic Simulation of Bridges
Publisher: American Society of Civil Engineers
Abstract: The paper summarizes trends presently being followed in the windtunnel simulation of bridges. Topics treated are scale factors, section, partialand full‐bridge models, testing under laminar and turbulent flow, and the ...
Bridge Flutter Derivatives at Vortex Lock-In
Publisher: American Society of Civil Engineers
Abstract: Many structures with extended spans undergo the flow-induced oscillation commonly called vortex shedding. In the case of long-span bridges, Ehsan and Scanlan, employing basic data from deck section wind tunnel model tests, ...
Mitigation of Severe Wind Damage Related to Ground Transportation Systems
Publisher: American Society of Civil Engineers
Abstract: The assessment of the highest winds to be expected in a given location has been accomplished for well‐populated areas by long‐standing data‐keeping on the part of meteorological agencies and the exercise of extreme‐value ...
Bridge Deck Aeroelastic Admittance Revisited
Publisher: American Society of Civil Engineers
Abstract: The subject matter of the present paper falls within the context of the analysis of the response to wind of long-span bridges. Although the paper stands alone, it should properly be seen as focusing on a single important ...
Estimates of Skew Wind Speeds for Bridge Flutter
Publisher: American Society of Civil Engineers
Abstract: When estimating the stability of a long-span bridge under wind, the basic study is most often made by considering the wind as it approaches the bridge at right angles to its long axis. However, maximum wind at a given site ...
Observations on Low-Speed Aeroelasticity
Publisher: American Society of Civil Engineers
Abstract: A brief history of developments in the field of low-speed aeroelasticity is provided in the context of application to long-span bridge structures. The paper begins with summary of some of the significant developments in ...
Bridge Buffeting by Skew Winds in Erection Stages
Publisher: American Society of Civil Engineers
Abstract: A theoretical framework for the buffeting analysis of incompleted bridges in the erection stage is first presented. The bounding cases of across‐deck and along‐deck wind flow are then treated. Intermediate considerations ...
