In trying to approach, analytically, the results of the tests
on the experimental plate, the case of an interior
panel of an infinitely large slab was used, This case produced
solutions of greater negative stresses at the columns
and lesser positive stresses at the center, than the experimental results. If an analogy is drawn between the slab supported on its welded columns and a single span bent, the
relationship between the experimental results and the analytical
results is similar to the relationship between the beam
of the elastic bent and the beam of one with infinitely stiff
columns. If this thesis is to be used as part of a basis for
further exploration into the interaction of slabs and columns,
it is suggested that the plate-bent analogy be carried further,
Just as the moment values in the beam of the elastic bent lie
between the values found by considering infinitely stiff
columns and columns with no stiffness, so will the moment
values in the slab lie between the cases of the interior panel of an infinitely large slab and a single panel hinged at the
four corners. It is therefore suggested that analytical solution based on a single panel hinged at the four corners
would produce a limit for the positive moments at the center
of the plate.
