IBC 17-89: Low-Cost Scour Preventing Fairings for Bridges
Roger Simpson, Ph.D., P.E. and Gwibo Byun, Ph.D., AUR, Inc, Blacksburg, VA
Cost-effective optimized versatile scour-preventing three-dimensional convex-concave hydrodynamic fairings with attached vortex generators have been designed, developed, and extensively tested (NCHRP-IDEA) for all types of bridge piers and abutments. They are available for retrofit or new bridge installation for any river level, speed, and angles of attack up to 45 degrees, unlike other countermeasures that do not prevent scour. They exceed HEC-23 requirements, prevent local scour for smaller sediments and the effects of open-bed scour on foundations.
IBC 17-90: Repair, Strengthening, and Re-use of Steel Girder Bridges: Two Case Studies
Brandon Chavel and Jacob Wroten, HDR, Cleveland, OH
Bridge repairs and strengthening techniques require careful consideration of the behavior of the structure and load paths through the repairs and construction sequencing. This presentation will discuss two case studies that required unique solutions to repair, strengthen, and modify the steel superstructure: a bridge where the first interior pier was relocated closer to the abutment and the subsequent superstructure strengthening; and a bridge that required a portion of beam replaced due to a full-depth fracture.

The Bayonne Bridge Navigation Clearance Program raises the roadway of the existing Bayonne Bridge to provide 215 feet of navigational clearance. The project rehabilitates the original 1931 steel arch bridge and replaces the aging approach structures on existing alignment using phased structure construction to maintain two lanes of traffic at all times. The presentation includes a brief overview of the arch design and construction, but focuses mainly on the new precast segmental approach structures replacement.
IBC 17-96: Joint Distress in Wide Precast Segmental Box Girder Bridges
Gregor Wollmann, HNTB, Blacksburg, VA; Theodore Zoli, HNTB, New York, NY
The Hathaway Bridge, located in Panama City, Florida, comprises two parallel, precast segmental concrete box girder bridges with 12 and 14 spans, respectively, erected in balanced cantilever construction. Since its opening in 2004 the bridge has exhibited continuous deterioration of the segment joints at and immediately adjacent to the cast-in-place closure pours between precast segmental cantilevers. This paper will discuss the mechanisms leading to the joint distress, the repair schemes to restore the structure, and the lessons learned from the project.
IBC 17-97: Balanced Cantilever Bridges of the Riyadh Metro Project
Douglas Heath, P.E., Latif Ebrahimnejad, Ph.D. and Firooz Panah, P.E., AECOM, Boston, MA
The Riyadh Metro Project is a large infrastructure project in the city of Riyadh, Saudi Arabia. This project involves the design of over 20kM of precast segmental elevated viaduct. Most of the viaduct consisted of simple spans; however at nine locations throughout the project, three span balanced cantilever bridges were used to avoid conflicts on the ground. This paper describes the design of the balanced cantilever bridges and discusses some of the challenges encountered.

IBC 17-99: Evaluation of the Failure of the Universidad Laica Overpass During the Pedernales Earthquake
Lissette Iturburu and Pedro Rojas, Ph.D., Escuela Superior Politecnica del Litoral, Guayaquil, Ecuador; Jose Barros, Universidad Católica de Guayaquil, Guayaquil, Ecuador
This paper discusses the collapse of the Universidad Laica overpass as a result of the Mw. 7.8 Pedernales Earthquake in Ecuador. The overpass was located in downtown Guayaquil at about 150 miles from the epicenter. From comparisons between the seismic demands and the shear capacity of the columns, it is concluded that the columns failed by shear due to pounding between the central span and the cap beam of the two central piers.

Justin Baird, P.E., Bryan Spangler, P.E. and Timothy Ainsley, II, P.E., Michael Baker International, Harrisburg, PA
The Albertus L. Meyers Bridge (aka 8th Street Bridge), is a historic gateway located in Allentown, Pennsylvania. The open spandrel arch bridge was constructed in 1913 and was listed on the National Register of Historic Places in 1988. The presentation will cover key components from design through construction of the 2016 rehabilitation. The rehabilitation included partial superstructure replacement and substructure renovation to increase the roadway width while maintaining aesthetics of the historic structure.
IBC 17-101: Truckee River Bridge – Tahoe City, CA: Seismic Analysis and Design of Torsionally Eccentric Cellular Abutments
Jon Emenheiser, P.E. and John Rohner, CH2M, Englewood, CO
The Truckee River Bridge in Tahoe City, California will bypass the city and provide trail access along both sides of the river. The trails will pass below the bridge and through cellular abutments. The abutment cell wall near the river will have openings for river views, resulting in torsional eccentricity. The elements were designed to remain elastic during the design seismic event and detailed to be ductile during a seismic event that exceeds design levels.
IBC 17-102: Design of a Long-Span Suspension Bridge Anchorage System Located in a High Seismic Region and Susceptible to Large Cargo-Vessel Impact
Michael Whitney, Bechtel, Houston, TX; Vahid Zanjani, Ph.D., P.E., McLaren Engineering Group, New York, NY; Robert Baldwin, P.E., S.E., P.Eng., Bechtel, Reston, VA
This paper discusses the design of an approximately 1200m long main-span suspension bridge anchorage system. The bridge is founded within extremely challenging strata consisting of very deep weak clays overlaying extremely incompetent weathered rock of variable depth and highly fractured. The anchorage foundation is composed of large diameter post-tensioned cast-in-place steel-shelled concrete piles, utilizing a unique battered arrangement. The paper highlights some of the unique design and construction aspects of the proposed anchorage system, given the poor soil conditions, to meet the challenging seismic and accident (due to large-vessel impact) design conditions.
IBC 17-103: Seismic Isolation of the Manhattan Approach Ramps to the Robert F. Kennedy Bridge
Andrew Adams, P.E., Modjeski and Masters, Mechanicsburg, PA; Blaise Blabac, Modjeski and Masters, Poughkeepsie, NY
This presentation focuses on the site specific seismic analysis of this unique steel rigid frame structure and the development of a continuous “floating deck” seismic isolation system consisting of both friction and elastomeric isolators. In addition to reducing the demands on seismically vulnerable regions (such as the riveted built-up member connections), use of a continuous deck reduced the number of expansion joints, making for a more maintenance-free structure.

W-07: Development of Spliced Precast Girder Bridge Technology
Time: 2:00–5:00 PM
Room: Magnolia 1
Presented By: Summit Engineering Group
The development of spliced precast bridges in the United States has steadily advanced over the last 62 years since the first bridge of this kind was built in Klickitat County WA in 1954. The concept was developed to increase potential span lengths beyond the limitations of what could be safely shipped to a project site. Since that time numerous bridges have been successfully constructed using this method. Span ranges have exceeded 300’ for some for projects. Recent advances include casting of curved U girder sections have made it possible to use precast for medium to long span interchange bridges with complex roadway geometry.
Design standards have been developed for and adopted by the Pennsylvania and Florida DOT’s to provide guidance to designers, fabricators and contractors for future projects. The Topics that the Workshop will focus on:
- Historical Development of the concept.
- Design and Analysis Techniques
- Design Details and Construction Practices
- Project Experiences
- Development of Design Aids and Standards
