【Abstract】 Based on the characteristics of the multi-stiffened plates,the buckling strength theory of continuous column with internal elastic supports under axial compression was used to derive the practical calculation formula for the critical load of wholly buckling.The validity of the formula was analyzed by comparing the theoretical results with numerical ones from FEM,which showed that the presented formula is simple for practical use with quite good results.更多还原
