AD.2006.1.4 Persistency of Parameters User to Generate ASCE Wind Load in STAAD Input File
In the past, once the wind load as per the ASCE-7 code was generated automatically using the wind load generator, no information about the parameters was retained by STAAD. So, there was no way to check the parameters, based on which the generation was done. Moreover, if any modification was required at a later stage, all the parameters had to be defined afresh. Automatic wind load generation feature has now been enhanced and the parameters can now be saved as part of the STAAD.Pro model.
Special tag based commands has now been introduced to support saving of ASCE parameters as part of the STAAD input file as shown below.

!> END GENERATED DATA BLOCKWhen a user goes back to the Load page and goes to Definitions | Wind Definitions page and double clicks on the Intensity as shown in the next figure,
the intensity versus height data shows up as shown below.
One can now click on the Calculate as per ASCE-7 button and the parameters that were initially defined are going to appear in the resulting dialog boxes.
