跨度30m以上的钢板梁,由于腹板较高,常有水平拼接。铁路桥梁检定规范中没有这一拼接的检定公式,为解决钢梁复检中这一实际问题,我们推导了以下的公式。 板梁挠曲时,腹板水平拼接处(图1)的上下腹板有相互错动的趋势,连结这一部位的 Span 30m above the steel beam, due to the higher web, often horizontal splicing. There is no verification formula for this stitching in the railway bridge inspection norms. In order to solve this practical problem in the review of steel beams, we deduced the following formula. When the girder is flexed, the upper and lower webs of the horizontal splicing of the webs (Figure 1) have a tendency of mutual dislocation,
