Spencer Creek Bridge – Precast Concrete Provides Major Components for a Deck Arch Bridge on Oregon’s Scenic Coastal Highway 101 (70), Keith Kaufman, Knife River, Harrisburg, OR
The superstructure includes composite precast voided slabs that are detailed for live load continuity. High performance concrete and stainless steel reinforcement combined with precast prestressed elements were specified to increase life expectancy of the new bridge and minimize impact to the environmentally sensitive creek.
Development of the Northeast Extreme Tee Beam for Accelerated Bridge Construction (79), Michael P. Culmo, CME Associates, Inc., East Hartford, CT and Rita Seraderian, PCI Northeast, Belmont, MA
The Northeast Region of PCI has recently developed a standard for a new beam called the Northeast Extreme Tee Beam or NEXT Beam. The goals of this new section are to provide a fast construction option for variable width bridges with spans up to 90 feet. The paper summarizes the design criteria and how the committee accomplished those goals.
Shear Strengthening of Reinforced Concrete Bridge Girders with FRP Laminates (80), Adel ELSAFTY, University of North Florida, Jacksonville, FL
This research investigates the effectiveness of using FRP laminates in strengthening bridge girders in shear. Two groups of reinforced concrete girders have been tested.
