本文分析了桥式起重机箱形主梁变截面长度计算.分析表明:适当加大变截面长度对梁的强度与刚度影响很小,使自重降低大约6%.
This paper analyzes the calculation of the variable cross-section length of the box girder of the bridge crane.The analysis shows that the proper increase of the cross-section length has little effect on the strength and stiffness of the beam, and reduces the dead weight by about 6%.
