Node Specification dialog
Used to specify rigid links or specialized linkages in the structure. This facility can be used to model special structural elements such as ties or a floor diaphragm which makes the floor rigid for in-plane movements. The process is to select a node to act as the master and then degrees of freedom for which the slave nodes are linked to the master. Internally, STAAD will perform an automatic bandwidth reduction.
Opens when Node is clicked on the Specifications - Whole Structure dialog.
It is called as such because the displacements of the slaved node will be based on the displacement of this Master node. From the drop-down list, select the node which should serve as the master node.
Floor Diaphragm tab
|Floor Level group||
Select one of the options as the method to define the floor level of the diaphragm.
Used when the YRange option is selected.
|Master Node Information group||
Select the method used to define the master node of the diaphragm.
|Define Floor Range||Set this option to define the floor range as a XZ range of coordinates or by manually selecting coordinates.|
