The damage occurred primarily at weldedbeam-to-column connections, which had been designed to act in a ductile manner and to be capable of withstanding repeated cycles of large inelastic deformation.
基本上破坏都出现在梁与柱的焊接处，而此处的韧性设计是为抵挡周而复始的大量建筑非弹性变化。

According to fatigue damage accumulation theory, test load of verified fatigue test on rail across beam and welded connections with integral joint of combined steel truss bridge was gotten.
依据疲劳损伤累积理论，确定了公轨两用钢桁桥轨道横梁与整体节点连接头验证性疲劳试验的试验荷载。
