摘要
对吊车梁绝对最大弯矩的计算,通常采用手册给出的公式直接计算得到;然而,该公式仅在一定情况下是正确的;通过结构力学影响线分析,指出其不足之处,而且给出了简便的改进计算方法。
The absolute maximum-moment of a crane girder is usually calculated with expressions provided by handbook. But some evidences show that this method sometimes is wrong. By influence line analyses, a simply improvement method is proposed.
