对八个含有正交异性钢桥面板角钢纵肋现场对接的试件进行了静力和疲劳试验研究，纵助接头采用手工仰焊，考虑了纵肋对中偏差．试验结果表明纵肋对中偏差对接头的疲劳性能有重要影响，经回归分析得到的疲劳强度曲线可达到我国钢结构设计规范GBJ17——88的第四类．正交异性钢桥面
Static and fatigue tests were carried out on eight specimens with in-situ butt joint of angle steel longitudinal rib with orthotropic steel deck. The test results show that longitudinal rib alignment has an important influence on the fatigue performance of the joint, and the fatigue strength curve obtained through regression analysis can reach the fourth category GBJ17--88 of China’s steel structure design code. Orthotropic steel deck
