Lymon C. Reese & Associates Projects in Structural Engineering |
Project Location: Austin, Texas
Client: Pickett, Kelm & Associates, Austin, Texas
Dates: May-1999 to August-1999
The City of Austin plans to extend South First Street to FM1626, with crossings over two arms of Slaughter Creek, in the City of Austin, Texas. Twin bridges, each of approximately 40-ft in width and with equal spans of 110-ft in length are planned for each crossing. The bridges spanning the main arm of Slaughter Creek, in the southernmost end, will each carry a walkway on one of their sides. The walkway will be suspended from the outermost prestressed-concrete girders.
Lymon C. Reese & Associates (LCR&A) was contracted by Pickett, Kelm & Associates (PKA) to investigate the dynamic response of the suspended walkway. Several linear-dynamic analyses were performed and results are reported in this document. Responses to roadway traffic and to vibrations induced by people were taken into account in the dynamic studies.
