结点力 meaning in English

joint forces

Many iterations are conducted in each time step . stiffness is constant in each iteration . nonlinear effect is transformed to equivalent unbalanced node force
该算法在每一时间增量内进行多次迭代，迭代过程中采用常刚度格式，把非线性效应转化为等效的右端不平衡结点力。
When reinforced concrete upper structure - piled raft - subsoil system is studied , every part of this system is looked upon homogeneous discrete space . accofding to static equivalent principle , equivalent node loads are calculated , and load embattle is integrated with element equivalent node force and directly bearing load
在分析时，本文将钢筋混凝土上部结构和地基、基础的研究问题视为各向同性空间问题，且按静力等效原则计算等效节点荷载，荷载列阵由单元等效结点力和直接作用于单元结点上结点荷载集成而得。
