  • Erection of Steel Bridges Across Large River for Shinkansen High-Speed Rail
    Abstract: In the construction of Japanfs Shinkansen high-speed rail lines, the use of steel bridges is very low. The steel bridges that were constructed on the lines were primarily selected because of the conditions of construction logistics, such as time constraints on the period of erection, operation time and construction space. To enable erection under these constraints, the steel bridges were constructed using various erection methods. For this reason, special erection methods are often taken into account in the structural planning stage as well.The Hokuriku Shinkansen, a new high-speed line to be inaugurated from Nagano to Kanazawa in 2014, crosses the Chikuma River twice. The length of the river reaches 367km and it is the longest among Japanese rivers. Nagano prefecture, the region of the construction sites, hosted the Winter Olympic Games in 1998 and is known for its heavy snowfall. Due to the rivers and heavy snowfall, it was required to construct the bridges under various severe constraints. For the construction of the Nanohana Bridge (Chikuma No.5 Bridge), the period for erection work was limited. For the construction of the Apple Bridge (Chikuma No.4 Bridge), it had to be erected using limited workspace. In order to overcome these restrictions, steel-concrete composite girder bridges were applied.This paper describes the erection planning and on-site work of the two bridges crossing the Chikuma River, which were constructed by using two different erection methods.

  • Lake Champlain Bridge Emergency Replacement Project
    Abstract: The Lake Champlain Bridge, also known as the Crown Point Bridge, was a historic steel truss bridge stretching 2,187 feet across Lake Champlain and connecting the rural communities of Crown Point, N.Y., and Chimney Point, Vt. It opened in 1929 with then-New York Governor Franklin D. Roosevelt at the ribbon-cutting. Since then, the bridge has served as a vital economic link between communities, which share hospitals and fire departments, as well as a link to the past but by 2009, the bridge had reached 80 years of service life, and a study was to be conducted to determine the need for possible major rehabilitation or replacement. Together with the Vermont Agency of Transportation (VTrans), the Federal Highway Administration (FHWA) and the HNTB design team, the New York State Department of Transportation utilized emergency standby contracts and an accelerated design-bid-build process to develop a plan to demolish the original truss bridge in just over two months, construct a temporary ferry service and to design and erect a new signature crossing in just over two years. The New Lake Champlain Bridge opened November 7, 2011 utilizing a process that could become a model for the nation.

  • Construction Engineering Recommendations for Curved and Skewed Steel Girder Bridges: Report for NCHRP Project 12-79, Task 9
    Abstract: The recently completed NCHRP Research Project 12-79, “Guidelines for Analytical Methods and Erection Engineering of Curved and Skewed Steel Deck-Girder Bridges,” investigated the analysis of curved and skewed steel girder bridges. Over 70 bridges were analyzed in detail using a variety of 1D, 2D, and 3D analysis methods; for each bridge the results of the various analysis methods were compared to benchmark 3D fine element analysis results or to field measurements (when available) to evaluate their accuracy. The results were evaluated to determine appropriate levels of analysis for erection engineering of various types of steel girder bridges. Numerous findings and recommendations representing significant advancements in the state of the art for erection engineering were generated. While a few of the recommendations involve improvements to commercial bridge analysis software and may take some time to implement, the remainder of the findings and recommendations can be implemented immediately by bridge engineers performing erection analyses. The NCHRP 12-79 research team provided a succinct and practical summary of these immediately implementable findings and recommendations, in a format useful to practicing bridge design engineers, in what they called the Task 9 report. This paper provides a summary of the NCHRP 12-79 Task 9 report recommendations.
