he response of the bridge structure

he response of the bridge structure when subjected to static loads of four axles on each span is shown in Table 1. In this table, the vertical deflections at the center of crown in Spans 1 and 2, the tangential strains along the centerline of the rail track at three different positions on Span 1 [quarter span (CR side), crown, and quarter span (K side)] and the transverse strains at the crown of Span 1 are shown. It is seen that the bridge behaves linearly for the three load levels applied over it. No visual cracking was seen during this test, and the structure unloaded elastically on load removal. The minor differences in the displacements of the two spans are indicative of the mild asymmetric nature that exists in the arch geometry. The transverse strains along the crown are seen to be tensile in nature.

他响应时静荷载作用下的四轨上每个大跨度桥梁结构如表 1 所示。在此表中，冠在跨度 1 和 2，在中心的垂直偏移沿铁路线中心线的切向压力跟踪在三个不同位置上的跨度 1 [季跨度 （CR 侧），皇冠，和季跨越 (K 侧)]，并显示在冠的跨度 1 的横向株。可以看出这座桥的行为与线性应用在它的三个负载级别。无视觉开裂被认为在此测试期间，结构弹性卸载负荷去除。中的两个范围位移的细微差异是指示性的拱几何中存在的不对称天性温和。沿冠的横向株被看作是拉伸的

他响应的桥梁结构时受到的四轴上的每个跨度静载荷，如表1所示。在这张桌子上，在跨越1和2顶中心垂直偏转，切向应变沿轨道中心线在三个不同的位置上的跨度1 [季度跨度（CR侧），冠，和季度跨度（K边）]和横向菌株在跨度1皇冠显示。可以看出，桥呈线性超过它的应用三负荷水平。没有视觉的开裂是在这个测试，和结构卸载弹性负载的去除。在两个桥墩的位移差异较小的轻微的不对称性在拱的几何形状的存在。沿顶横向应变看在本质上被拉伸。
