摘　　要：在钢结构设计中,稳定是必须考虑的一个重要问题。文章以钢梁的弯扭屈曲为例,提出钢梁弯扭屈曲理论存在的问题,简要介绍了张文福教授提出的板-梁理论和弹性约束下钢梁弯扭屈曲的研究现状,并对今后需要研究的问题提出展望。Stability problem is the key issue which should be taken into account in the structures. In this paper, the studies on the flexural-torsion buckling are taken as examples. The theory of flexural-torsion buckling of steel beam is firstly pointed, and then the Plate-Beam design of steel problems of the Theory and the related flexural-torsion buckling of steel beam with elastic constrains are briefly introduced. Finally, the prospects for future research directions are put forward.

关 键 词：钢梁稳定 弯扭曲屈 弹性约束
