Kansas City Southern Railway Company

Open-deck timber trestles on a mainline railroad had deteriorated to a level requiring replacement.  Calculations were prepared based on a Cooper E-80 loading for replacing the timber beams with steel beams.  STADD/III® structural analysis software was utilized to model the traveling load and design the beams in accordance with the American Railway Engineering Association’s Manual for Railway Engineering. Modifications and repairs to existing pile bents and caps were also designed to accommodate the new steel stringers.  Engineering and fabrication drawings were prepared and provided to the owner’s construction group.
