摘要
当钢构件的长细比较小而截面的抗扭及抗翘曲刚度均较低时有可能发生弯扭屈曲 ,《钢结构设计规范》(GBJ 17- 88)对这种构件均只计算其弯曲屈曲 ,对其可能发生扭转屈曲的问题没有特别的规定。鉴于此种情况给出了具体计算方法 。
When slenderness ratio of a steel member is relative small,and rigidity of torsional section is relative weak,it is possible for a flexural-torsional buckling to occur.“Code for Design of Steel Structure”(GBJ 17-88)only provides the calculation of flexural buckling of this sort of member,but gives no special consideration on twisting buckling.The article gives specific calculating ways about this situation and introduces foreign country’s calculating ways.
