At a rigidjoint of a space frame, three resolution and three moment equations can be written.
在空间框架的一个刚性节点处，可以写出三个分力方程和三个力矩方程。

Because the ideal "rigidjoint" and "hinged joint" are inexistent, the stiffness of any connection types is between ideal rigidjoint and hinged joint.
因为理想的刚节点和铰接点是不存在的，任何连接形式的刚度都是介于理想刚接和完全铰接之间的。

In order to resist the structure's lateral load and reduce the lateral displacement efficiently in the tier or tall building structure, it is generally designed the joint as rigidjoint earlier.
