The effects of the difference in mechanical properties on the post-buckling behavior of stub-columns were investigated. Mild steel plates and two different types of high-strength steel plates were examined. High-strength plates have almost the same tensile strength of about 7tonf/cm^2, while their yield ratios were different: one is 74% (low yield ratio) and the other is 93% (high yield ratio). The stub-columns have cruciform section and they were built up by welding from the steel plates. The width-thickness ratios of the outstanding parts were from 5 to 15. The ultimate strength was controlled by buckling almost in the inelastic range. This tests yielded the equations to predict the load-deformation characteristics in the whole range including the degrading part.
