IBC 08-51 - Erection Engineering Considerations for Horizontally Curved Steel I-Girder Bridges
Brandon Chavel, PE, Shawn Tunstall, PE, Matt Bunner, PE, Jason Fuller, PE, HDR Engineering, Inc., Pittsburgh, PA

The erection of horizontally curved steel I-girder bridges can be complex. This paper will highlight aspects of curved steel I-girder bridge erection that should be considered by the design engineer and constructor's engineer in the development of the steel erection plans, so as to provide for a successful bridge construction project.

IBC 08-52 - Erection of the Twin-Box Steel Deck for Stonecutters Bridge

With a main span of 1018m, Stonecutters Bridge is a landmark cable stayed bridge across the entrance to the Hong Kong container terminals. The twin-box steel girder deck is one of the first of its kind, requiring innovative methods of analysis and erection techniques during construction.

IBC 08-53 - Incremental Launching of Final Composite Bridge Deck

Launching of final composite bridge deck has all advantages of launching method such as erection speed, lower costs and high quality of the bridge. Further innovation for composite bridges is the position of sliding bearings and the sliding trace structure. We decided to launch the structure supported on the concrete slab (bottom Surface) next to the beam web. The concrete slab at this location is connected to the steel flange by means of studs and the beam web acts as a very rigid stiffener.

IBC 08-54 - Rapid Set Bridge Deck Overlays on the SR 376 Parkway in Pittsburgh, PA
Edward Liberati, PE, HTNE Hydrodemolition Services / Modified Concrete Suppliers, Hilliard, OH

Presentation will include a detailed discussion and power point of the fast track weekend bridge deck repairs of the Parkway Bridges in Pittsburgh, PA. 21 bridge decks were repaired with Latex Modified Concrete Overlays in just 14 weekends. By utilizing innovative construction techniques and rapid set materials, work was able to be performed with minimal disruption to the 125,000 vpd which use the parkway. The existing bridge decks will now be preserved for another 25 years.

IBC 08-55 - Design and Construction of the Providence River Bridge
Patricia Steere, PE, Yihui Wu, Maguire Group Inc., Providence, RI

The design and construction of the 400-foot arch span of the Providence River Bridge was recently completed in Providence, RI. This span is a three-ribbed steel network arch design with a ten degree skew. The advantage od a network arch cable arrangement over an arch bridge with vertical cables is that it reduces the superstructure weight but still maintaines adequate stiffness. The advantages are discussed, as well as the study that was used to determine the cable arrangement, the effect of the skew on the design, the method used to provide internal redundancy to the tie chord, and other design considerations.

IBC 08-56 - The Construction of Si Du River Suspension Bridge
Yinbo Liu, H & J International, PC, Collegeville, PA; Chongxu Wang, Road & Bridge Southern China, Zhongshan, China; Yuancheng Peng, CCSHCC, Second Highway Consultants Co. Ltd, Wuhan, China

The paper presents the key aspects of the construction of a 1222 meter long suspension bridge over Si Du river in the deep mountainous area in central China. The bridge spans over a 550 meter deep valley, which is the highest suspension bridge in the world. The challenges facing the construction include: limited working area, complicated geological conditions, restricted transportation access to the site, special wind gust conditions, and restricted access for superstructure installation.

IBC 08-57 - Replacement of a Rare Hanover Skewed Bascule - the Hamilton Avenue Bridge
Keith Griesing, PE, Hardesty & Hanover, LLP, New York, NY

The rarely seen hanover skew bascule, also known as a knee-girder bascule bridge, is a unique and complex movable structure. The replacement of the skewed Hamilton Avenue Bridge with a new, fully operational span in sixty-four days created a one-of-a-kind project that challenged the owner, designers and constructor.
