internal reaction force

基本解释

The static characteristics of the single pylon cable-stayed include the internal force and deformation of main girder, reaction force, force and deformation of the main tower.
独塔混凝土斜拉桥的静力特性主要包括主梁受力及变形、支座反力、主塔受力及变形、拉索受力。
Not only that it has a direct impact on the spread and settlement of soil reaction (base pressure), but it also affects the internal force and deformation of the foundation and superstructure.
它不仅直接影响地基反力（基底压力）的分布和基础的沉降，而且影响基础和上部结构的内力和变形。
The sum of work of effect and reaction has nothing to do with the choice of criterion. With this conclusion, it is very easy to work out the sum of particle and work of internal force.
利用作用力做功和反作用力做功的代数和与参照系的选择无关这样的结论，计算质点组的内力作功之和将非常简捷方便。
