在火力发电厂中,预制吊装的梁柱刚性节点很多,无论是主广房或是其它构筑物中,都有相当可观的数量。目前,这些刚性节点的设计如图1所示。图1所示是梁断面下部仅2根钢筋的设计,梁端下部设两个豁口以便焊接钢筋。但有三个缺点:一是当梁宽较小时,梁端在牛腿上

In thermal power plants, there are many rigid beams and columns for prefabricated cranes, and there are considerable quantities of them in the main buildings or other structures. At present, the design of these rigid nodes is shown in Figure 1. Figure 1 shows the design of only two steel bars in the lower section of the beam. Two gaps are provided at the lower end of the beam to weld the reinforcement. But there are three disadvantages: First, when the beam width is small, the beam ends on the shins
