Numerical Approach of Interaction between Wave and Flexible Bridge Pier with Arbitrary Cross Section Based on Boundary Element Method
Publisher: ASCE
Abstract: A numerical approach based on potential theory and the boundary element method (BEM) to study the interaction between surface waves and a flexible bridge pier will be developed. The conventional hydrodynamic approach in ...
Influence of Wind Turbulence on Aerodynamic Admittances of a Streamlined Bridge Deck at Different Angles of Attack
Publisher: ASCE
Abstract: This study revisits the modeling of buffeting forces on bridge decks and establishes the relationship between one- and two-wavenumber admittances, and between the spanwise coherence functions of turbulence and buffeting ...
Nonlinear Safety Analysis of a Running Road Vehicle under a Sudden Crosswind
Publisher: American Society of Civil Engineers
Abstract: Threats of wind gusts on the safety of road vehicles have been reported around the world, and extensive studies have been carried out to find the accident speeds of road vehicles under a sudden crosswind. However, most ...

Stochastic Response Assessment of Cross-Sea Bridges under Correlated Wind and Waves via Machine Learning
Publisher: ASCE
Abstract: The stochastic response of cross-sea bridges is susceptible to the significant effects of wind and waves. In this study, an efficient probabilistic assessment framework for cross-sea bridges was developed by combining a ...
Influence of Vehicle Inertia Force on Vertical Vibration of Long-Span Suspension Bridge under Wind and Traffic Loads
Publisher: ASCE
Abstract: The long-span bridges could frequently experience complex dynamic interactions with wind and traffic, which makes the dynamic response evaluation crucial for ensuring structural and vehicle driving safety. Previous studies ...
Analyzing Wind-Induced Snow Redistribution on Box Girder Bridges Using Wind Tunnel Tests
Publisher: American Society of Civil Engineers
Abstract: With the increase in span, the flexibility and sensitivity to aerodynamic damage of bridges significantly increase. However, current research studies primarily focus on analyzing the single environment, leaving the safety ...
Spectrum Models for Nonstationary Extreme Winds
Publisher: American Society of Civil Engineers
Abstract: Nonstationary extreme winds are responsible for many structural damages. However, empirical models are not available for these winds, especially for fluctuations, mainly due to the difficulties in mathematical treatments. ...
Aerodynamic Effects of Viaduct-Cutting Connection Section on High-Speed Railway by Wind Tunnel Tests
