桥梁检定规范自1978年6月试行以来,各桥检队对旧梁进行了检算,发现有一些上承板梁腹板稳定性不够,但是这些梁已经经过了长时间的考验,并没有发现不良情况,据有的桥检队反映,即使解放以后建的新梁,跨度24米以上的亦有腹板稳定检算不够的情况。在此对腹板稳定计算的一些看法介绍如下。 Since the trial of the bridge test in June 1978, the bridge inspection team conducted an examination of the old beam and found that some of the upper web girders are not stable enough, but these beams have been tested for a long time and have not been found According to some inspection team, even if the new beam was built after the liberation, the stability of the web was not checked enough for a span of more than 24 meters. Here are some ideas for web stability calculations.
