Equipment properties

Properties
Name The automatically generated name for the equipment.
User Name Can be used to override the automatically generated name if required.
Type
The following types are available:
  • Sphere
  • Vertical Cylinder
  • Horizontal Cylinder
  • Cuboid
Diameter, D Diameter of sphere or cylinder.

Used to determine the Cf value.

These values are also used in the calculation of wind loads on open structures seen by the equipment.

For more information, see: Wind load calculation for equipment

Length, L Length of cuboid or cylinder.

Used to determine the Cf value.

Breadth, B Breadth of cuboid.

Used to determine the Cf value.

Height, H Height of cuboid.

Used to determine the Cf value.

Base position, z Entering a non-zero value raises/lowers the equipment above/below the loading area.
Angle to Global X Can be used to rotate the equipment relative to global X
CoG offset Can be used to offset the equipment relative to the global or local axes
Empty Load
Apply Load Load can either be applied at CoG or at Supports.

This load is created in the Equipment Empty loadcase.

Load Enter a single value if at CoG, or individual values at each support.
Operating Content Load
Apply Load Load can either be applied at CoG or at Supports.

This load is created in the Equipment Operating Content loadcase.

Load Enter a single value if at CoG, or individual values at each support.
Testing Content Load
Apply Load Load can either be applied at CoG or at Supports.

This load is created in the Equipment Testing Content loadcase.

Load Enter a single value if at CoG, or individual values at each support.
Wind loading
Apply open structure wind load

Select this flag if you want open structure wind loads to be calculated.

For more information, see: Open structure wind loads

Surface For vertical and horizontal cylinders, specify the surface as either, moderately rough, rough, or very rough.

For cylinders the surface and L/D ratio are used to determine the Cf value

End For horizontal cylinders, specify the end as either flat, or rounded.

This is used to determine the Cf value, see ASCE 7 Fig 6-21
