RISA Composite Model for Vehicle Formation and Path Selection on a Cellular Structured Map
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new framework for multiple vehicle system modeling and control is proposed in this paper, emphasizing team behavior in a multilevel, multiresolutional way. This framework integrates issues like ...
Active Noise Hybrid Feedforward/Feedback Control Using Neural Network Compensation*
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nonlinear active noise control (ANC) is studied. The nonlinear ANC system is approximated by an equivalent model composed of a simple linear sub-model plus a nonlinear sub-model. Feedforward ...
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 ...

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. ...
