New Mathematical Formulation of Nonlinear Unsteady Wind Loads on Long-Span Bridge Decks under Nonstationary Winds Using Time-Delay Neural Network
Publisher: ASCE
Abstract: This paper presents a novel mathematical formulation of unsteady wind loads on bridge decks by using the neural network technique while incorporating the concurrent effects of nonstationary winds and aerodynamic nonlinearity. ...
Blast-Loading Effects on Structural Redundancy of Long-Span Suspension Bridge Using a Simplified Approach
Publisher: ASCE
Abstract: Long-span suspension bridges are typically designed against wind and earthquake loadings without considering blast loads because existing blast-resistant design guidelines for bridges are limited and in fact not detailed ...
A Simplified Approach for Dynamic Analysis of Suspension Bridges under Extreme Limit State
Publisher: American Society of Civil Engineers
Abstract: The design of suspension bridges predominantly emphasizes wind and earthquake loads, frequently overlooking the consideration of extreme events in the design stage, thus posing a threat to bridge safety. The purpose of ...
