• Abstract:
  Several new truss bridges are planned throughout the state. Currently, the bridge railing proposed for these structures consists of a standard Texas Department of Transportation (TxDOT) railing, the T101, which is supported by a cast-in-place concrete deck. TxDOT would prefer to have the option to support a bridge rail system from the truss members in lieu of supporting the railing from the concrete deck. The primary advantage of using a truss-supported bridge rail is to allow alternate types of deck. One disadvantage to using a truss-supported bridge rail is the bridge structure must be adequately designed to resist the crash loads imparted from the bridge rail directly to the truss members.
