Structural Performance of Longitudinally Post-Tensioned Precast Deck Panel Bridges
As the aging bridges and infrastructure within the US continue to deteriorate, traffic delays due to construction will become more and more common. One method that can reduce delays due to bridge construction is to use precast deck panels. Precast deck panels can significantly reduce the overall …

Hydraulic modeling and performance evaluation of low water crossings in Illinois
… in the State of Illinois. There are many old and aging bridges, culverts, and low water crossings on rural low-volume roads that need to be replaced. Low water crossings (LWCs) have been used as an economical alternative to culverts and bridges, designed without overtopping, on low-volume roads …

Integration of Traffic and Structural Health Monitoring Systems Using A Novel Nothing-On-Road (NOR) Bridge-Weigh-In-Motion (BWIM) System
Bridges are vital components of the U.S. transportation network. However, every year, the transportation agencies report a large number of aging bridges that are structurally damaged. Also, evolving traffic and particularly the overloaded traversing traffic can threaten the bridges' integrity and …
