BUCKLING OF THIN RECTANGULAR PLATES WITH TWO INSIDE POINT SUPPORTS

This paper proposes an analytical solution for the problem of buckling of thin simply supported rectangular plates with two inside point supports, which are uniformly compressed in one direction. The numerical results of the nume- rical factor k of critical compressive force, calculated from the various values of the ratio a/b and the various positions of the point support, and the relat- ions between the two reactions of point support during buckling of the plates are both given here.
