THE SECONDARY STRESS EFFECT ANALYSIS OF COLD-FORMED THIN-WALL STEEL TRUSS
-
摘要: 采用有限元对冷弯薄壁型钢焊接平行弦钢桁架由于节点几何缺陷在杆件中产生的次应力进行分析,对由节点构造形式所产生的次应力大小及分布规律、次应力产生的原因以及次应力对冷弯薄壁型钢桁架结构受力性能的影响进行分析。Abstract: Using finite element method, it is analysed and studied the secondary stress in the member bar of cold-formed thin-wall steel truss due to node geometric flaw. It is also analysed that the secondary stress values and regularities of distribution as well as the reason of generating secondary stress and its effect on cold-formed thin-wall steel truss structure.
