Snow loadcases (Eurocode)

This section will look at the snow loadcases when the headcode is set to Eurocode.

The snow loadcases that are set up will depend on the head code that is being worked to.

Note:

All loads and lengths of loads are assumed to act on a horizontal projection of the roof surface.

Once set up these loadcases are standard loadcases so you can include them in combinations in the normal manner.

In the Snow wizard... you choose the Snow Loadcases to be set up from the following list:

Snow Load - Case A - 1) Undrifted
Snow Load - Case A - 2) Drifted *
Snow Load - Case B1 - 1) Undrifted Snow Load - Case B1 - 2) Drifted *
Snow Load - Case B1 - 3) Undrifted (Acc)
Snow Load - Case B1 - 4) Drifted (Acc) *
Snow Load - Case B2 - 1) Undrifted
Snow Load - Case B2 - 2) Drifted *
If any drifts from Annex B are selected
- Snow Load - Case B2 - 3) Drifted (Annex B) (Acc) *
Snow Load - Case B3 - 1) Undrifted

Snow Load - Case B3 - 2) Drifted *
Snow Load - Case B3 - 3) Undrifted (Acc)
If any drifts from Annex B are selected
- • Snow Load - Case B3 - 4) Drifted (Annex B) (Acc) *

Note:

For cases marked * - the number of cases actually set up will depend on the number of wind directions that are asked for.

Note:

The Eurocode / National Annex recommends which loadcases to generate.

Undrifted loadcases

Any undrifted loadcases that have been set up in the Snow wizard... are automatically populated with uniform loading on completion of the wizard

Drifted loadcases

All drifted loadcases that have been set up in the Snow wizard... would need to be have their snow loads manually applied on completion of the wizard.
