Estimation of Tropical Cyclone–Induced Wind, Rainfall, and Wave Multihazards for Selected Coastal Cities in China
Publisher: American Society of Civil Engineers
Abstract: The southeastern coast of China experiences severe casualties and economic losses every year due to tropical cyclones (TCs), most of which are attributed to TC-induced wind, rainfall, and wave hazards. Estimating TC-induced ...
Aerodynamic and Aerostatic Performance of a Long-Span Bridge with Wide Single Box Girder Installed with Vertical and Horizontal Stabilizers
Publisher: ASCE
Abstract: The continuous increase in traffic volume requires wider single box girders for long-span cable-supported bridges. Flutter and aerostatic instability are challenging issues for these flexible bridges, especially when they ...
Nonstationary Characteristics of Short-Rise-Time Gusts in a High-Altitude Deep-Cut Canyon
Publisher: American Society of Civil Engineers
Abstract: A short-rise-time gust is a typical nonsynoptic wind with abrupt changes in mean speed and turbulent intensity, which differs from normal winds at plain sites. Field measurements were conducted in a high-altitude deep-cut ...
Extreme Typhoon Wind Speed Mapping for Coastal Region of China: Geographically Weighted Regression–Based Circular Subregion Algorithm
Publisher: ASCE
Abstract: The coastal region of China is exposed to severe typhoon threats and suffers significant casualties as well as economic losses due to seven to eight landed storms every year. This study developed a geographically weighted ...
Probabilistic Gust Factor Model of Typhoon Winds
Publisher: ASCE
Abstract: The gust factor commonly is used in wind engineering community to convert mean wind speeds into gusty winds, which exhibit significant variability in real observations of typhoon winds. This study proposes a probabilistic ...
Instantaneous Power Balance Algorithm for Flutter Critical Wind Speed Prediction of Bridge Girders
Publisher: ASCE
Abstract: Wind-induced vibration has become increasingly prominent for long-span bridges. Flutter instability, as a type of divergent vibration, is a key component in the wind resistance investigation of long-span bridges. Based on ...
Experimental Uncertainty Quantification of Flutter Derivatives for a PK Section Girder and Its Application on Probabilistic Flutter Analysis
Publisher: ASCE
Abstract: Aerodynamic flutter instability could lead to the catastrophic collapse of flexible long-span bridges and needs to be prevented. This study investigated the variability of eight experimentally measured flutter derivatives ...
