  • BR1a
  • Paper Mill Road Bridge


    This 360' long, three-hinged, arched truss bridge on Paper Mill Road over The Gunpowder Falls in Baltimore County, Maryland was rated using the working stress method. The bridge was built in 1930, and is believed to be the only one of its kind in the state. The structure was modeled using the STRAN software package.
  • BR2a
  • Manchester Bridge


    The "Manchester" Bridge is a mile-long, multiple-span, steel girder bridge over the James River in Richmond, Virginia. The main spans feature pin and hanger details, and the ramp spans are constructed of horizontally curved girders. The main spans were modeled using BAR 7. Descus was used to model the ramp spans. The rating was done using the load factor method.
  • BR3a
  • I-895 SB Ramp Bridge


    This structure is a horizontally curved steel girder bridge carrying the I-895 SB ramp over I-95 in Howard County, Maryland. The main span is a two-span continuous unit (225' and 164') and the approach spans are simple spans (73' and 64'). A working stress rating using curved girder software was provided.
  • BR4a
  • Mayo Bridge


    The "Mayo" Bridge is a mile-long, multiple span, reinforced concrete arch bridge over the James River in Richmond, Virginia. The bridge was modeled using STAAD 3. Influence lines and bending/thrust interaction diagrams were hand-constructed, from which the rating factors were computed. The load factor method was utilized.
  • BR5a
  • Wisconsin Avenue Bridge


    This structure is a 292' long (3-span continuous) "hybrid" steel girder bridge carrying Wisconsin Avenue over the Capital Beltway. The flanges of the girders were constructed of grade 50 steel, while the webs were constructed of grade 36 steel. A working stress rating was provided utilizing the BAR 5 software package.
