The factor to be used to multiply the wind loads.
The factor is always positive and the direction is selected separately.
||Select the global direction in which the wind load acts.
Wind load sign conventions for Custom wind
- To see how these
signs correspond to analytical wind load data, compare to the
STAAD.Pro Wind Load help. Not Internal
command is used in STAAD.Pro. Rather, it is interpreted as shown above.
- For SP 16.13330
(Russian) wind loads, the factor sign controls the direction instead.
custom wind definitions only) Set this option to indicate an internal, or
suction, wind force on the surfaces (i.e., the load direction is reversed). If
selected for a Russian wind load case, the Internal option is ignored but a
warning message will appear when sent to the analytical model.

option is only applicable for rectangular buildings.
Pressure Coeff (Nu)
||Specify the wind pressure correlation coefficient. If parameter is
omitted or is exactly 1, a computed value is used instead. For rectangular
buildings, the correlation coefficient is always calculated automatically, thus
any specified value will be ignored.
Method to use for assigning the wind load to
the building projection.
- Automatic – No
additional action required as the program will apply the wind load to the
entire projection of the structure perpendicular to the selected Direction.
- Specify Range –
Maximum X/Y/Z and
Minimum X/Y/Z global coordinates to
limit the application of the wind load.
- Groups – Click
