Moreover, the finite element analyses described in this
paper are applied to conduct comparative studies and to assess
the relative effect of various factors on the structural response
of jointed rail to applied loads. Such factors include: discrete
tie support (i.e. supported joint versus suspended joint with
varying spans between effective ties), bolt pattern (four versus
six bolts), initial bolt tension, and easement. In addition, results
are shown for 90 lb rail joined with long-toe angle bars
compared to 136 lb rail joined with standard short-toe joint
bars.
