Wind Load Generator Error

[bylar]

I have been using STAAD's Wind load generator to analyse window walls and have had good sucess but i have found this problem which I believe to an error in STAAD and I wonder if anyone else has had the same problem?

As long as the wall is perpendicular to the wind the forces are distributed properly but if I turn the wall at 45 degrees to the wind no forces show up on the joints of the wall.

What I have is a wall that forms a prowl, that is at 45 degrees to the x axis and then turns 90 degrees which is again at 45 degrees to the x axis and the reaction and joints show values (value of 0)

Has anyone else had this experience?

 

I remember having similar kind of problem while using Staad.Pro 2001.Apparently it was a limitaion in Wind Load Generation. Until 2001 wind load could be generated only on the Panels perpendicular to the direction of wind.

However, this limitation is no longer there. I have recently installed 2002 and the new enhanced wind load generator can handle inclined panels also (inclined in any direction). I used it for a few problems and worked really well.
