| Abstract: | The forced behavior of large-sized thin-walled tubes members subjected to bending is analyzed by nonlinear finite element. The influence of several factors on stability capacity of these members subjected to bending is taken into account. Thus according to correlative design standard of steel structures, and on the basis of numerical results by the F. E. methods, the calculation formulas of the stability bearing capacity are presented for the members subjected to bending. |

| Keywords: | large sized thin-walled steel tubes stability beating capacity of members subjected to bending initial imperfections slenderness ratio |
