焊接钢结构节点及杆件组合形式的合理与否,直接影响到整个结构的质量。评价节点及杆件的组合形式是否合理,应当看它是否便于施焊,保证足够的强度与刚度;焊后杆件的残余应力和变形是否小于一定值,是否充份利用了材料的承载能力以及是否便于维 The reasonableness of the welded steel structure joints and rods forms directly affects the quality of the entire structure. The evaluation of the combination of nodes and rods is reasonable, it should be seen whether it is easy for welding, to ensure adequate strength and stiffness; residual stress and deformation of the post-weld rod is less than a certain value, whether the full use of the material carrying capacity and Is it easy to dimension
