| Select Type
|
Choose the method of specifying wind pressure values from the
drop-down:
- Custom – ASCE 7 or other
user-specified wind pressures
| Setting | Description |
|---|
| Intensity vs. Height table |
Enter pairs of data for wind pressure at a
given height (in the current units). Int cells – wind intensities (pressures) in force/area. Up to
100 different intensities can be defined in the input file per type.
Height cells – corresponding heights in global vertical direction,
measured in terms of actual Y (or Z for Z UP ) coordinates up to which the
corresponding intensities occur.
|
| Calculate as per ASCE 7 |
Opens the ASCE-7 Wind Load dialog, which is
used to generate a wind load per the ASCE 7
specification. Input data on the type of structure,
surrounding terrain, and wind. |
- SNiP
2.01.07-85 or SP
20.13330.2016 – Russian wind load parameters
| Setting | Description |
|---|
| Pressure |
the characteristic value of wind pressure, always
positive
|
| Terrain |
terrain roughness category:
- Coastal Zone.
- Urban Zone.
- Large City.
|
| Region |
Wind region as per clause 11.5 of SNiP 2.01.07-85*
2016. This is used to determine the wind pressure in determine the dynamic wind
component.
|
| Delta |
logarithmic decrement of
oscillations, Delta (see table 11.5 - Section 11.1.8 for the definition).
Typically values are:
- 0.15 for steel towers, masts, lined
chimneys, column means including the ones on the reinforced concrete pedestals
- 0.3 for reinforced concrete and stone
structures as well as for buildings with steel framework if there are walling
structures

- GB 50009-2012 - Chinese wind load parameters
| Setting | Description |
|---|
| Generate Wind Load |
Opens the Generate Wind Definition and Wind
Load Case for Chinese GB 50009 dialog,
which is used to enter code parameters for generating
wind intensity values based on the GB 50009 2012
code. |
