Abstract

A description of a frame to support 4-ft×8-ft reinforced-concrete plates which are being tested in compression to determine their buckling characteristics is presented. The frame, which is used in a universal testing machine, accommodates plates of different thicknesses, all of which are simply supported along all edges. Results of tests on plates with thicknesses of 3/4 in., 1 in, and 1-1/4 in are presented in order to evaluate the effectiveness of the frame in satisfying theoretical loading and support requirements. All of the plates buckled in a “plate-buckling” mode (biaxial curvature) instead of a “column-buckling” mode (uniaxial curvature).

Methods for evaluating the buckling loads from experimental data included use of deflection profiles, application of Southwell’s method and use of strains in the buckled partion of the plate. It was concluded that by using results of strain readings taken from gages located at the center of the buckled zone in the plate, an accurate estimate of the load at which buckling initiates could be obtained.
