潘先生的方法是利用預先算好的多种表格来决定梁的形常数及載常数,再用角变位移方程解求各段上的端轉动及端位移,由此求出端弯矩汝端剪力,实質上就是用角变位移法解彈性地基上的阶形梁,它的优点在于各項形常数及載常数都能利用表格迅速求出,但必須注意到角变位移方程的数目要随着梁的段数而增加,例如在一个不对称的三段梁內,便要解一组四元联立方程,四段梁內,要解一组六元联立方程等等,这就成为角变位移法的弱点,笔者認为,採用下述初参数法不仅可以免去解多元联立方程的麻煩,还可以將需用的公式和表格減到最低限度。
Mr. Pan’s method is to determine the beam shape constants and load constants using a variety of pre-calculated tables, and then use the angular displacement equation to solve the end rotation and end displacement on each segment, and then find the end bending moment. End shear force, in essence, is the use of angular displacement method to solve the stepped beam on the elastic foundation. Its advantage is that all form constants and load constants can be quickly found by using the table, but it must be noted that the angular displacement equation The number will increase with the number of beam segments. For example, in an asymmetrical three-segment beam, a set of four-element simultaneous equations will be solved. Within a four-segment beam, a set of six-element simultaneous equations will be solved. It is the weak point of the angular displacement method. The author believes that the following initial parameter method can not only avoid the trouble of solving multiple simultaneous equations, but also can minimize the required formulas and forms.
