The limiting slenderness of T-section stems prescribed in the Code for Design of Steel Structures (GBJ17-88) is too restrictive so as to hinder the promotion of using the hot-rolled cut T-section. It is shown that the critical stress of the interactive buckling of the plate elements is the same as that of the member in torsional buckling about the shear center axis. When a T-section member satisfies the verification on flexural -torsional buckling, there is generally no need to perform a buckling check...

The limiting slenderness of T-section stems prescribed in the Code for Design of Steel Structures (GBJ17-88) is too restrictive so as to hinder the promotion of using the hot-rolled cut T-section. It is shown that the critical stress of the interactive buckling of the plate elements is the same as that of the member in torsional buckling about the shear center axis. When a T-section member satisfies the verification on flexural -torsional buckling, there is generally no need to perform a buckling check for plate elements. However a too slender stem may buckle by itself instead of interactive buckling so that a limiting width-thickness ratio is sun necessary. Suggestion is made for revising the relevant clause of the Design Code. The stability of T- section beam-column stems is also investigated.

《结构设计规范》(GBJ17-88)对T形截面压杆腹板高厚比的限值规定得过严,影响剖分T型钢的推广应用。分析表明:T形截面压杆板件相关屈曲的临界应力等同于杆件绕剪心轴扭转屈曲的临界应力。当杆件满足弯扭屈曲验算要求后,一般无须再对局部稳定进行验算.但是,高厚比很大的硬板也有可能单独屈曲,因而仍然需要对腹板高厚比加以限制。为此提出了相应的建议。此外,还对T形截面压弯构件的腹板稳定进行了分析。

For cold- formed lipped channels, under compression or bending, there are three buckling modes, plate local buckling, section distor-tional buckling and overall flexural or tensional - flexural buckling. This paper emphasizes the interaction of plate local buckling, the calculation of section distortional buckling stresses and the interaction of three buckling modes. It indicates that there is defect of the current effective area method for the design of cold - formed lipped channel members. The direct strength...

For cold- formed lipped channels, under compression or bending, there are three buckling modes, plate local buckling, section distor-tional buckling and overall flexural or tensional - flexural buckling. This paper emphasizes the interaction of plate local buckling, the calculation of section distortional buckling stresses and the interaction of three buckling modes. It indicates that there is defect of the current effective area method for the design of cold - formed lipped channel members. The direct strength method using the complete cross - section of the members are illustrated through examples.

受压或受弯的冷弯薄壁卷边槽钢有板件局部屈曲,截面畸变屈曲和整体弯曲屈曲或弯扭屈曲三种模式。本文着重介绍板件的相关屈曲和计算截面畸变屈曲应力的方法并阐述了三种屈曲模式之间的相关关系。指出用传统的有效截面设计法计算受压和受弯冷弯薄壁卷边槽钢承载力的弊端,较详细地说明了用构件全截面计算的直接强度设计法。
