摘要
对目前应用与研究较多的几类方矩形冷成型钢管柱-H型钢梁连接节点以及铸钢节点按构造形式和受力机理进行分类,并对各自的技术经济指标进行对比分析;概述铸钢节点的优点和推广的可能性。通过对这些节点形式的技术经济指标的比较分析,表明每种节点都有其固有的优点和不足,寻找一种技术经济各方面性能都很优异的节点形式是不现实的,在实际选择和开发节点时要根据具体情况扬长避短,工程设计人员要根据节点所在结构的受力特点选择合适的节点形式。
Some kinds of connections between cold-formed rectangular tubular columns and H-shaped beams were presented, the connections were classified by their construction and loaded mechanism and their indexes in terms of technology and economy are compared, respectively. The excellence and the probability of popularization of cast steel joint were stated. From comparing the technology and economy items of every kinds of joint, it was illuminated that it is difficult to find some kinds of joints that are excellent in every facet because there are inertia merits and demerits included in every kinds of joints. What should be done is to exploit the favorable facets and avoid the unfavorable ones. Engineers and designers should choose proper type of joints according to the loaded condition of the structure.
