The FEA also indicated that the residual stress only has little effect on the overall bucklingresistance of the ultrahigh strength steel columns.
计算结果还表明，残余应力的变化对超高强度钢材焊接工形截面轴心受压柱整体稳定承载力的影响较小。

If these elastic restraints action of bucklingresistance is taken into account the critical loads of steel members may apparentely been increased and plenty of steel material is saved.
利用连接构件之间约束作用，钢构件的稳定临界荷载可以得到显著的提高，节约大量的钢材。

The major purpose of the paper was to investigate the resistance capability of plates to local buckling in concrete filled steel tube by elastic buckling analysis of steel plates.
