Entering and analysing seismic bracing of the fire extinguishing system
Within the "Installation" tab, in the "Bracing" group of the main toolbar, there are tools for entering seismic bracing and for assigning them a zone of influence consisting of a given set of pipes of the fire extinguishing system:
Seismic bracing
Enters seismic bracing into the model.
When entering or editing a seismic bracing, the following parameters can be configured:
- Reference
Seismic brace reference. - Seismic brace
Defines the type of seismic bracing from the following options:- Lateral sway brace
The bracing is arranged to be perpendicular to the pipe it supports. - The bracing is arranged in the same direction as the pipe it supports.
- Four-way sway brace
Two-directional bracing to support vertical pipes.
- Lateral sway brace
- Support composition
Defines the components of the seismic bracing. The program can select components from the "Library of generic elements" using the wizards available on the right. These types of elements can be created and edited from the "Library of generic elements" option in the "Project" group.- Sway brace (Series / Type)
- Brace (Series / Type)
- Fastener (Series / Type)
- Arrangement of the support
- Angle
Angle of the support measured with respect to the vertical line. - Fastener position
- Horizontal force, perpendicular to the surface
- Vertical force, perpendicular to the surface
- Force parallel to the surface
- Angle
The seismic bracing must then be arranged in the model on a given point of a pipe of the fire extinguishing system.
It is then necessary to assign the pipes in the zone of influence of the bracing using the corresponding option in the same group.
With the data supplied, when carrying out the analysis, the program performs the following checks on the seismic bracing, which can be consulted and listed in the corresponding section of its editing panel:
- Pipe size
Checks that the pipe size of the sway brace is equal to or greater than the diameter of the pipe it holds. - Distance between hangers
Checks that the distance between hangers does not exceed the maximum value. - Maximum brace load
Checks that the load assigned to the brace does not exceed the maximum value allowed by the selected component types. - Maximum fastener load
Checks that the load assigned to the fastening does not exceed the maximum value allowed by the selected component types.

Checks that the load assigned to the brace does not exceed the maximum value allowed by the selected component types. - Maximum fastener load
Checks that the load assigned to the fastening does not exceed the maximum value allowed by the selected component types.
Also, by clicking on the "Consult checks" option, a complete data sheet with the data, the detail plan and the analysis results of the selected bracing can be obtained.
Assign
Assigns or unassigns pipes of the fire extinguishing system to certain seismic bracing.
When clicking on a seismic brace, a dialogue box appears where users choose whether they wish to "Assign" or "Unassign" pipes to it. After accepting, the program lights up the pipes that are already assigned to it or those that are not yet assigned, depending on the selected operation. This way, the desired pipes can be selected to complete the operation.
