Line ancillary properties
| General | |
|---|---|
| Name | The automatically generated name for the ancillary. |
| User Name | Can be used to override the automatically generated name if required. |
| Width, W | Width of ancillary |
| Type |
The following types are available:
1 These types expose the Guardrail flag below. 2 This type exposes the Measuring property and Guardrail + channel height, H1 value below. 3 These types expose the Guardrail height, H1 value below. 4 This type exposes the Category and Diameter of largest pipe values below. 5 This type exposes the Category and Height of Cable Tray values below. |
| Default Load Values | If this option is selected, load values for the selected type (with or without guardrail) are obtained from Model Settings > Loading, if unselected, load values can be entered directly. |
| Dead Load | Load to be created in the Ancillary Dead loadcase |
| Live (Imposed) Load | Load to be created in the Ancillary Live (Imposed) loadcase |
| Measuring (Live/Imposed) | For stairs choose whether the live/imposed load is a vertically projected load, or measured along the element. |
| Live (Imposed) Load loadcase |
If working to Eurocodes, some ancillaries may require different Ψ and ɸ factors in which case a new loadcase should be manually added with the desired factors. To create the load in the new loadcase select it here. |
| Empty Load | Load to be created in the Pipework Empty, or Cable Tray Emptyloadcase |
| Operating Content Load | Load to be created in the Pipework Empty, or Cable Tray Emptyloadcase |
| Operating Content Load loadcase |
If working to Eurocodes, some cable trays may require different Ψ and ɸ factors in which case a new operating content loadcase should be manually added with the desired factors. To create the load in the new loadcase select it here. |
| Testing Content Load | Load to be created in the Pipework Testing Content loadcase |
| Category | For cable trays and pipework, the default load values from Model Settings > Loading are those for the selected category. |
| Guardrail | If this option is selected, the default load values from Model Settings > Loading are those for the selected type with guardrail. |
| Guardrail height, H1 | The value specified here is used in the calculation of wind loads on open structures seen by the ancillary. |
| Guardrail + channel height, H1 | The value specified here is used in the calculation of wind loads on open structures seen by the ancillary. |
| Height of cable tray, H | The value specified here is used in the calculation of wind loads on open structures seen by the ancillary. |
| Diameter of largest pipe | The value specified here is used in the calculation of wind loads on open structures seen by the ancillary. |
| Height, H | The value specified here is used in the calculation of wind loads on open structures seen by the ancillary. |
| 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 |
| Shape factor, Cf | The default shape factor varies according to the entity type and is
taken from Model Settings > Loading > Wind Loading Note: Default
Cf factors are taken from the document ‘Wind Loads For Petrochemical And
Other Industrial Facilities’ published by ASCE. |
| Effective area XY | |
| Formula | The default effective area formula varies according to the entity type and is taken from Model Settings > Loading > Wind Loading |
| Factor | The factor used in the above formula can be edited if required. |
| Effective area XZ | |
| Formula | The default effective area formula varies according to the entity type and is taken from Model Settings > Loading > Wind Loading |
| Factor | The factor used in the above formula can be edited if required. |
| Reverse | For lines of pipework/cable trays the height is displayed and it can be visually reversed by checking this flag. |
