||Choose the method of specifying wind pressure values from the
- Custom – ASCE 7 or
other user-specified wind pressures
|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.

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
