This paper offers a simple method for computing the effective length of two-stepped columns. The mathematical model is based on the calculation of geometrical figures by graphic method and the solution is obtained by successive approximation. This method is simpler and more convenient than that of solving the equation of stability critical condition, especially when the column is connected at its top with elastic beam, the results obtained by this method have the same precision as required.

The critical equations of buckling of a rectangular sheet , which is compressed at two opposite simply supported edges and is stretched at the other two built-in edges , is obtained by the energy method. Analysis of the buckling of non-uniform stretching problems of sheets with this equation yields the critical load coefficent of buckling, with which it is proved that Yoshida Buckling Test (YBT) and the non-uniform stretching of a rectangular sheet which has relevent sizes are identical in their critical points of buckling. That means as a simulative test YBT is feasible for non-uniform stretching problems.
