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, you can fix the dome edges are fixed to rotation and/or translation, or you can solve it is solved together with the structure with the semi-rigid diaphragm acceptance solution.

Boundary conditions for separate solution

Image Modified

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

Image Modified

 

If checked, the selected edge is restrained against translation.

Rotation restrained

Image Modified

 

If checked, the selected edge is restrained against rotation.

Boundary conditions for solution with building system

Image Modified

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

Image Modified

The edge of the dome is considered a fixed support.

Connection distance

Image Modified

Give the amount of distance that will be required for the dome edge to be attached to the support.
