Northeast Solid Deck Beam Guide Details 1st Edition was developed by the PCI Northeast Bridge Technical Committee. The Solid Deck Beam is designed to improve the durability of adjacent beam bridges, eliminate concrete topping slabs, reduce labor at the job site, and reduce the overall structure thickness. The lack of draped (harped) strands and internal voids is a significant benefit during fabrication. Eliminating transverse post-tensioning and special shear key grouts saves considerable time during construction. Solid Deck Beam will be an excellent solution for Accelerated Bridge Construction for bridge spans up to 55 feet.
