如题，请教各位大哥 SLAVE ZX MASTER 35 JOINT 是什么意思，为什么要做这样的设定呢

主从节点假定。“SLAVE ZX MASTER 35 JOINT” 命令的意思就是ZX平面假定刚性，主节点为35节点。这类命令主要模拟刚性楼板，肩梁等。下图为软件指定界面。可以指定不同平面或方向的自由度刚性假定。

谢谢了
这个 主从节点 是什么意思呢，请教

The master/slave option is provided to enable the user to model rigid links in the structural system. This facility can be used to model special structural elements like a rigid floor diaphragm. Several slave joints may be provided which will be assigned same displacements as the master joint. The user is also allowed the flexibility to choose the specific degrees of freedom for which the displacement constraints will be imposed on the slaved joints. If all degrees of freedom (Fx, Fy, Fz, Mx, My and Mz) are provided as constraints, the joints will be assumed to be rigidly connected.
The master/slave option provided in STAAD allows the user to model specialized linkages (displacement tying, rigid links) in the system.  For example, SLAVE  FY … connects the two joints such that the Y displacement at the slave will be the sum of Y displacement at the master plus the rigid rotation.
