摘要
本文介绍了12根冷弯薄壁槽钢组合工字形截面偏心受压柱试验。试验验证了《冷弯薄壁型钢结构技术规范》(GBJ18—87)中压弯构件弯扭稳定性相关公式的适用性。文中通过计算证明:正是由于常用构件的自身特征值φy和φb属于非弹性不同步,使得相关公式在实际应用中略偏安全。
The test results of 12 I- section beam- column specimens composed of 2 cold- formed channels have been studied and reported.They verify the applicability of the interaction formula for lateral - torsional buckling of beam- columns adopted in the Specification for Design of Cold- Formed Thin- wall Steel Structures (GBJ 18- 87). The calculating results show that the predications of the formula in the Specification is slightly safe in practice, because of the inelastic properties of φ y and φ b of the member are non- synchronous.
