Restraints are defined with the Set Dome/Vault Restraints command. Before the dome calculation is made, it is necessary to determine the support properties of the dome edges. With the Set Dome/Vault Restraints command, the dome edges are fixed to rotation and/or translation, or it is solved together with the structure with the semi-rigid diaphragm acceptance solution.
Location of Set Dome/Vault Restraints Command
After entering the dome command, you can access the Set Dome/Vault Restraints command from the dome toolbar.
Usage Steps
-
Click the set dome/vault restraints icon.
-
The Set Boundary Conditions dialog will open.
-
Click on the edge of the dome for which you want to change the boundary conditions.
-
In the set boundary conditions dialog, select the option you want.
-
Click the OK button to exit the dialog.

Boundary conditions for separate solution 
If a solution is made with the assumption of a fully rigid diaphragm, the dome is solved separately from the structure. In this case, the support conditions of the dome edges are determined by two options: rotation and translation. Dome loads should also be applied to the structure. |
|
Translation restrained 
If checked, the selected edge is restrained against translation. |
|
Rotation restrained 
If checked, the selected edge is restrained against rotation. |
|
Boundary conditions for solution with building system 
If the solution is made with the assumption of semi-rigid diaphragm, the structure - the dome is solved together. In this case, the objects to which the edges of the domes are connected are determined by the options given in the dialog. |
|
Fixed 
The edge of the dome is considered a fixed support. |
|
Connection distance 
Give the amount of distance that will be required for the dome edge to be attached to the support. |
