本文讨论了弹性地基梁计算中两个需要解决的问题.首先根据文献中的简化方案,编制了空间问题短梁通用反力系数表,可适用于任意荷载,包括边荷载,并指出各个系数的力学意义;其次给出了承受集中弯矩载长梁无量纲系数和承受集中力载长梁无量纲系数间的相应微分关系,因此可根据文献中对后一情况己编制的系数表利用差分法算出前一情况时的计算系数。配合己有的刚性梁系数表,使弹性地基梁计算全部表格化。
In this paper, two problems to be solved in the calculation of elastic foundation beam are discussed.At first, according to the simplified scheme in the literature, a generalized reaction coefficient table of space beam is developed, which can be applied to any load, including side load, and pointed out that each coefficient Mechanics significance. Secondly, the corresponding differential relationship between the dimensionless coefficient of beam subjected to concentrated moment and the dimensionless coefficient of beam subjected to concentrated force is given. Therefore, according to the coefficient table compiled in the literature for the latter case, the difference method Calculation of the previous case of the coefficient. With the existing rigid beam coefficient table, the elastic foundation beam calculation is all tabulated.
