摘要:
在钢管塔结构的设计中,节点刚度是重要参数,随着高强钢在变电构架中的应用,对高强钢相贯节点抗弯刚度的研究日趋重要.本文对Q690高强钢管相贯节点采用瓦形板加强、内隔环加强和内套筒加强的三种加强方式进行了试验研究,得出不同加强方式对节点刚度的影响,并以欧洲规范中节点初始刚度的判断准则分析了节点的刚度性能,得出对于采用Q690高强钢的人字柱加强型相贯节点不能按照刚性节点进行设计,而应作为半刚性节点进行设计;最后对瓦形板及内隔环对节点的作用机理进行了分析说明.
Abstract:
The joint stiffness is an important parameter in the design of steel tower structures. With the application of high strength steel in the substation frame structures, research on the flexural rigidity of the tubular joints that are made of high strength steel has become increasingly important. In this paper, an experiment study was conducted on three types of tubular joints which were enhanced by tile shaped plate, inner annular plate, and inner sleeve respectively, in order to get the influence of different reinforcement on the joint stiffness. By analyzing the different parameters of each enhanced method, the influence of various parameters on the joint stiffness was obtained. The stiffness performances of each joint were analyzed by the joint initial stiffness criterion specified in the European specification. The results show that the Q690 high strength steel enhanced tubular joints should not be taken as rigid joints in engineering design, but as semi-rigid joints. The action mechanism of tile shaped plate and inner annular plate on the tubular joint was explained at last.
