RISSimplified System-Level Pavement-Stiffness Model for Box Culvert Load-Rating Applications
Publisher: American Society of Civil Engineers
Abstract: Tens of thousands of aging, bridge-class, RC box culverts are in service in the United States. Within the context of establishing load rating for in-service RC box culverts, this paper introduces, calibrates, and applies ...
Improved Load Rating of Reinforced-Concrete Box Culverts Using Depth-Calibrated Live-Load Attenuation
Publisher: American Society of Civil Engineers
Abstract: This paper describes depth-calibrated live-load attenuation for the load rating of reinforced-concrete box culverts using production-simplified models. In-plane depth calibration is accomplished using a production-simplified, ...
Uncertainty Analysis and Quantification of the AASHTO Live Load Distribution Model for Moderately Buried–Reinforced Concrete Box Culverts
Publisher: American Society of Civil Engineers
Abstract: RC box culverts are buried structures prevalent in transportation systems. The existence of backfill brings in additional challenges to estimate load demands in these structures. The AASHTO LRFD specifications present a ...
