摘要
推导了薄壁构件相邻板件之间的约束关系,介绍了我国《冷弯薄壁型钢结构技术规范》(GB50018—2002)考虑板组效应的计算方法,并以矩形薄壁构件为基础,在不同的宽厚比要求下,运用我国规范计算方法,经过计算对比其有效截面面积,考虑板组效应对矩形薄壁构件截面承载力的影响.
The restraint relationship between the thin -walled elements is firstly explained. The calculative method about plate assembly effect in the current Chinese Technical Code of Cold - Formed Thin - Wall Steel Structures（ GB50018 -2002） is then introduced. Using this code, rectangular thin- walled member under different width- thickness ratios is taken as a basic unit to calculate and compare effective section area, which helps to find out the influence on bearing capacity of rectangular thin - walled member when plate assembly effect is considered.
