Vibration of a Bridge Under a Random Train of Moving Loads
The vibration of a beam resulting from the passage of moving loads is a problem of great importance in structural dynamics. A consistent model for the description of the loads acting on...

A Fatigue Reliability Model for Railway Bridges
A fatigue reliability model is described for safety evaluation of steel railway bridges. The model is a function of six independent random variables and can accommodate different types...

Transportation Lifeline Losses in Large Eastern Earthquakes
In December 1991 Applied Technology Council (ATC) and its subcontractor, EQE Inc., completed a 2-year Federal Emergency Management Agency-sponsored study to assess the seismic vulnerability...

Rehabbing the Rails
In 1984, during a routine bridge inspection, a worker detected deterioration under the south abutment of a bridge that carried the main line of Philadelphia's commuter railroad....

Special Considerations for Railroads
In comparison with highway bridges, railroad bridges are generally characterized by a larger ratio between traffic and dead load, larger braking forces, smaller relative width of the bridge...
