Abstract: Multispan bridges with simply supported girders are straightforward to construct and economical but have historically utilized expansion joints between spans. The negative long-term impacts of expansion joints are ...

Abstract: Precast bent caps offer the opportunity to reduce onsite labor and materials and to accelerate the speed of construction. For many bridges, the weight is manageable for shipping and placement without the need for large ...

Abstract: Undesirable cracking is commonly observed in existing bridge bents with inverted-T bent caps at the web-to-ledge interface. Although the cracking is unexpected, such cracks may decrease service life and are possible signs ...

Abstract: Accelerated bridge construction using precast bridge substructures can enable reduction of traffic disruption, increased worker safety, and increased quality through controlled conditions at the time of fabrication. A ...

Abstract: Precast, prestressed bent caps are an attractive design option because they permit accelerated bridge construction and can extend the service life of bridges by reducing or eliminating the service-level cracking observed ...
