Opening the Snow/Wind Load dialog and clicking the Snow tab displays the following dialog.
The dialog is divided into several fields with groups of specific options. The top of the dialog has the options for snow loads. When the Snow option is selected, a snow load is generated.
The options for sand loads are below the Snow option. When the Sand option is selected, a sand load is generated.
Beneath the Snow gathering field are the following options:
- Snow redistribution - Generates a snow load that accounts for snow slipping from roofs, snow blowing off roofs, and snow collecting behind various obstacles (gutters and acroterions). The default snow loads are generated with regard to the snow redistribution on roof planes.
- Gutters - Specifies the envelope nodes in which additional obstacles have been placed to prevent snow from slipping roof planes. These obstacles force the snow to stay on roof planes and increase the roof load locally. Envelope nodes can be entered manually or graphically.
- Obstacles.
