      James Ray; Cary D. Butler (American Society of Civil Engineers, 2004)
      Prior to any military operation, a critical task of military engineers involves the ability to quickly assess the load-carrying capacity of bridges. These assessments are required to facilitate the selection of movement ...
    • Fatigue of Joints with Staggered Holes 

      Georg Josi; Gilbert Y. Grondin; Geoffrey L. Kulak (American Society of Civil Engineers, 2004)
      It is customary in contemporary design for fatigue resistance of bolted connections to use slip-critical joints. However, many existing bridges are more likely to have bearing-type joints that use either rivets or high-strength ...
    • Orthotropic Plate Model for Estimating Deflections in Filled Grid Decks 

      Christopher Higgins (American Society of Civil Engineers, 2004)
      Concrete filled grid bridge decks exhibit orthogonal elastic properties and significant two-way bending action enabling orthotropic plate theory to determine structural response for these elements. Current American Association ...
    • Lateral Pedestrian Excitation of Footbridges 

      T. M. Roberts (American Society of Civil Engineers, 2005)
      The phenomenon of synchronized lateral pedestrian excitation of footbridges has been highlighted in recent years by the widely publicized problems encountered with the London Millennium Footbridge. On opening day, during ...
    • Estimation of Length Limits for Integral Bridges Built on Clay 

      Murat Dicleli; Suhail M. Albhaisi (American Society of Civil Engineers, 2004)
      In this paper, the maximum length limits for integral bridges built on clay are determined as a function of the ability of steel H-piles supporting the abutments to sustain thermal-induced cyclic displacements and the ...
    • Simplified AASHTO Load and Resistance Factor Design Girder Live Load Distribution in Illinois 

      Daniel H. Tobias; Ralph E. Anderson; Salah Y. Khayyat; Zeyn B. Uzman; Kevin L. Riechers (American Society of Civil Engineers, 2004)
      Illinois began full transition to the American Association of State Highway and Transportation Officials load and resistance factor design (LRFD) bridge design specifications from the traditional load factor design code ...
    • Truck Loading and Fatigue Damage Analysis for Girder Bridges Based on Weigh-in-Motion Data 

      Ton-Lo Wang; Chunhua Liu; Dongzhou Huang; Mohsen Shahawy (American Society of Civil Engineers, 2005)
      Based on data collected by weigh-in-motion (WIM) measurements, truck traffic is synthesized by type and loading condition. Three-dimensional nonlinear models for the trucks with significant counts are developed from the ...
    • Structural Analyses of Two Historic Covered Wooden Bridges 

      Dylan M. Lamar; Benjamin W. Schafer (American Society of Civil Engineers, 2004)
      Structural analyses were conducted of two covered wooden bridges still in use in the Summer of 2002. The Pine Grove Bridge and Brown Bridge represent the 19th century truss forms of the Burr-arch truss and the Town-lattice ...
    • Assessment of Multispan Masonry Arch Bridges. II: Examples and Applications 

      Antonio Brencich; Ugo De Francesco (American Society of Civil Engineers, 2004)
      Modern approaches to multispan masonry bridges are approximate in many ways: load distribution, masonry degradation, fill-to-barrel, span-to-span, and span-to-pier interaction are taken into account by means of approximate ...
    • Applications of Laser-Based Instrumentation for Highway Bridges 

      P. A. Fuchs; G. A. Washer; S. B. Chase; M. Moore (American Society of Civil Engineers, 2004)
      This paper describes a Federal Highway Administration Nondestructive Evaluation Validation Center (NDEVC) project to develop tools to better measure large-scale structures. The specific instrument discussed is a laser-based ...

      Unknown author (American Society of Civil Engineers, 2004)
    • Use of Glass-Fiber-Reinforced Polymer Tendons for Stress-Laminating Timber Bridge Decks 

      Habib J. Dagher; Frank M. Altimore (American Society of Civil Engineers, 2005)
      Researchers at the University of Maine led an effort in the mid-1990s to develop and use glass-fiber-reinforced polymer (GFRP) tendons, instead of the commonly used steel-threaded bars, for stress-laminating timber bridge ...
    • Forces in Wingwalls of Skewed Semi-Integral Bridges 

      Eric Steinberg; Shad M. Sargand; Christopher Bettinger (American Society of Civil Engineers, 2004)
      In theory, semi-integral bridges with skewed approaches have a tendency to rotate toward the acute corners due to thermal expansion. This movement causes force to be transferred into the wingwalls that are often designed ...
