      M. Schlaich (American Society of Civil Engineers, 2001)
      For the construction of composite steel-concrete decks of cable-stayed bridges, methods of erection and analysis have to be applied that, upon completion of the deck, accurately yield the prescribed dead load configuration ...

    • Alternative Layout for the Prestressing of Slab Bridges 

      L. T. Stavridis (American Society of Civil Engineers, 2001)
      On the basis of a statically admissible moment redistribution in rectangular and skew slab bridges with free edges parallel to the bridge axis, an alternative positioning of the prestressing tendons concentrated at the ...

    • Seismic Behavior and Retrofit of Outrigger Beam-Column Frames 

      A. Griezic; W. D. Cook; D. Mitchell (American Society of Civil Engineers, 2001)
      A one-fourth scale outrigger beam-column frame with as-built details was tested to assess its performance under reversed cyclic loading and to develop a retrofit procedure suitable for moderate seismic regions. The ductility ...

    • Strength and Ductility of HPS-100W I-Girders in Negative Flexure 

      Richard Sause; Larry A. Fahnestock (American Society of Civil Engineers, 2001)
      In current AASHTO LRFD bridge design specifications, the nominal flexural strength of I-girders made from steel with a yield stress >345 MPa (>50 ksi) is limited to the yield moment rather than the plastic moment and ...

    • Theory and Full-Bridge Modeling of Wind Response of Cable-Supported Bridges 

      Nicholas P. Jones; Robert H. Scanlan (American Society of Civil Engineers, 2001)
      As is well known, long, suspended bridge spans require, in the design stage, careful study of their resistance and response to site winds. This has driven, on the one hand, detailed quantitative observation of bridge models ...

    • Full-Scale Field Failure Tests of Railway Bridge 

      Emmanuel “Manos” Maragakis; Bruce M. Douglas; Qingbin Chen (American Society of Civil Engineers, 2001)
      Full-scale ultimate load tests were conducted in March 1995 on the bearings of the Strawberry Park Bridge, a two-span, 45 m (148 ft) long ballasted railway bridge typical of many such bridges around the country. The bridge, ...

    • Seismic Restrainer Design Methods for Simply Supported Bridges 

      M. Saiidi; M. Randall; E. Maragakis; T. Isakovic (American Society of Civil Engineers, 2001)
      Existing restrainer design methods recommended by the American Association of State Highway and Transportation Officials (AASHTO) and the California Department of Transportation (Caltrans) to prevent unseating in simply ...

    • Strength and Ductility of RC Beams Repaired with Bonded CFRP Laminates 

      G. Spadea; R. N. Swamy; F. Bencardino (American Society of Civil Engineers, 2001)
      The objective of this study is to investigate the strength and ductility aspects of reinforced concrete (RC) beams strengthened with an externally bonded carbon fiber reinforced polymer (CFRP) laminate and to examine how ...

    • Design Recommendations for Externally Restrained Highway Bridge Decks 

      J. Thorburn; A. A. Mufti (American Society of Civil Engineers, 2001)
      A severe maintenance penalty exists for composite multibeam highway bridges in areas where the use of deicing chemicals is prevalent. This maintenance concern is largely due to the corrosion of embedded steel reinforcing ...
