RISExperimental Evaluation of Load Transfer Mechanisms in Steel Truss Bridges under Varied Damage Scenarios
Publisher: American Society of Civil Engineers
Abstract: Abstract This paper investigates the structural robustness of a steel Pratt-type truss bridge
through a series of experimental analyses focusing on various damage scenarios. Twelve
distinct damage scenarios were examined ...
Analyzing Multiple Modal Interactions Induced by Internal Resonances in Cable-Stayed Structures Using Machine Learning Techniques
Publisher: American Society of Civil Engineers
Abstract: Abstract Nonlinear oscillations induced by modal interactions are commonly observed in cable-stayed
bridges, which are complex to investigate through numerical simulations. Given this
challenge, this paper conducted a ...
Identifying Critical Category Combinations of Bridge Cables at Risk of Internal Resonances Using Data Mining Technology
Publisher: American Society of Civil Engineers
Abstract: Abstract Fan-shaped cable nets in cable-stayed bridges (CSBs) exhibit a dense spectrum of local
frequencies, some of which inevitably lie close to global frequencies. This proximity
increases the risk of internal resonances ...
Long-Term Corrosion Mechanisms and Resistance of Steel Bars Coated with Quartz Sand-Modified Enamel Embedded in Mortar
Publisher: American Society of Civil Engineers
Abstract: AbstractIn this study, the long-term corrosion performance of steel bars coated with quartz
sand-modified enamel (QSME) in mortar cylinders was studied by immersing them in a
sodium chloride solution for 540 days. The ...
Monitoring, Modeling, and Assessment of a Self-Sensing Railway Bridge during Construction
Publisher: American Society of Civil Engineers
Abstract: This study shows how integrating fiber optic sensor (FOS) networks into bridges during the construction stage can be used to quantify preservice performance. Details of the installation of a large FOS network on a new ...
