摘　　要：介绍了芜湖长江大桥采用的更为先进的焊接整体节点。通过对大比例尺模型进行静载试验，测量了节点应力分布，并用有限元法对节点进行了分析；通过对节点施加疲劳荷载，分析整体节点各构造细节的疲劳强度。The still more advanced welded integral panel points used for Wuhu Changjiang River Bridge are introduced. By static load testing of a large scale model of the panel points,stress distribution on the points are measured, which are then analyzed with finite element method. By applying fatigue load to the points, the fatigue strength of each structural detail of the points are analyzed as well, and finally,comments on the fatigue resistance of the points are made.
