Base Plate Design5-12The unstiffened base plate thickness
is calculated using normal elastic theory.For a stiffened base
plate, however, the required plate thickness is determinedusing
yield line theory. If tensile forces are dominant, the number of
bolts used also influences the plate thickness.Analysis of the
boltsIn the case of the base plate bearing on the concrete or
grout, the bolts are designed to resist tensile forces only. For
the case where the bolts are used as studs, the bolts are designed
to resist the full compressions and tension forces. It is then
assumed that there is no bearing stress on the concrete orBase
