Lateral Load Distribution and Deck Design Recommendations for the Sandwich Plate System (SPS) in Bridge Applications
… key issues that will be studied include lateral load distribution, dynamic load allowance and deck design methodologies. With SPS being new to the market, there has only been a single bridge application, limiting the investigations of in-service behavior. The Shenley Bridge was tested under live …

Long-term In-service Evaluation of Two Bridges Designed with Fiber-Reinforced Polymer Girders
… for two years. Researchers have conducted load tests at both bridges to determine if their performance has changed during their respective service lives. The key design parameters under consideration are: deflection, wheel load distribution, and dynamic load allowance. The results from the …

Rehabilitation of timber railroad bridges using glass fiber reinforced polymer composite wraps
This study involves the rehabilitation and load testing of 50 + year old open deck timber railroad bridges on the South Branch Valley Railroad (SBVR) in Moorefield, WV. The rehabilitation involved repairing substructure elements including a "Pile cap/pile" joint and an above ground pile with Glass …

New Truck Loading Model For Rural Bridges In Saskatchewan
… existing information on estimating the critical load effects occurring on short span bridges, on low traffic roadways, and over specific reference periods makes it difficult to perform the bridge evaluations with an adequate degree of confidence. This study focuses on aspects of the estimation of …
