RISFatigue Crack Detection Using Unmanned Aerial Systems in Fracture Critical Inspection of Steel Bridges
Publisher: American Society of Civil Engineers
Abstract: Many state agencies are investigating the use of unmanned aerial systems (UASs) for bridge inspections. Some agencies are receiving pressure from consultants and their own administrations to implement UAS inspections with ...
Live-Load Testing and Long-Term Monitoring of the Varina-Enon Bridge: Investigating Thermal Distress
Publisher: American Society of Civil Engineers
Abstract: During detailed visual inspections, inspectors on the Varina-Enon Bridge noticed a significant flexural crack opening, visually estimated at 1.5 mm under traffic, on the last span of the approach structure among other ...
Investigating the Potential of Predicting Field Performance of Commercially Available High Early Strength Materials for Concrete Deck Repair Using Experimental Data
Publisher: American Society of Civil Engineers
Abstract: AbstractHigh early strength (HES) repair materials have been increasingly used in repair projects
across the United States due to their rapid strength gain, minimizing road closure
and traffic disturbance. This study aimed ...
On the Structural Reliability of the Horizontal Shear Limit State for Concrete Insulated Wall Panel Connectors
Publisher: American Society of Civil Engineers
Abstract: AbstractPartially composite insulated wall panels (IWPs) have been used in the construction
of buildings for over 100 years. Still, their design remains outside of major building
codes, and strength reduction factors ...
