本文在等直梁初参数法的基础上,对于有中间支承及联接的多跨梁,引入若干中间参数,并利用奇异函数和广义分布载荷的概念,写出梁的剪力、弯矩、转角和挠度的一般表达式,因而能用于求解在各种载荷和各种支承及联接条件下的多跨梁.此法特别适用于电算及计算机自动绘图,是其又一优点. In this paper, based on the initial parameter method of equal straight beams, several intermediate parameters are introduced for multi-span beams with intermediate supports and joints, and the shear force, bending moment, and corner of the beams are written using the concept of singular functions and generalized distributed loads. General expressions of deflection and deflection can therefore be used to solve multi-span beams under various loads and various supporting and coupling conditions. This method is especially suitable for computer calculation and computer automatic drawing and is another advantage.
