Elastic-plastic shear buckling of square plates with square holes is investigated experimentally. The plates are subjected to in-plane shearing deformations, and have edges supported stiffeners which Have three kind of thickness. Ratio of the square hole length to the plate length, a/1, are 0.3, 0.5 and 0.7. Experimental stresses along the plate edges show good agreement with finite element analysis except the largest hole a/1=0.7 in which the finite element mesh is relatively coarse. At the hole corners where there are maximum stress concentration, experimental stresses are much larger than the analysis in larger holes. Thicker edge stiffeners decrease the stress concentration at the hole edges and increase the buckling strength of the perforated plates rather than the unperforated. Experimental buckling strength of perforated plates with the ratio a/1=0.3, 0.5 and 0.7 is 0.51, 0.35 and 0.16 times of the unperforated plates respectively.
