Hi
I have attached a staad file for roof structure , which is at level 169 m of building roof .
But it shows member failure ,showing HSS TORSION and I am not able to find out the reason , plz help.

Thank u Jae ,
I will use these coefficients but could u plz tell me as there are 2 cases in Fig 6-18
for roof angle 0 degree - clear wind flow and obstructed flow
My structure is roof structure which starts at 41.2m level of building and ends at 47.85 m level .
span 10.6m
width 8.1 m
height of roof structure one side 6.65m and other side 2.15m
I calculated qh as 1.47 KN/m2 , G = 0.86
1. I considered wind load as per ASCE 7-05 with pressure...
Attached details .
The canopy is flat with building http://files.engineering.com/getfile.aspx?folder=1c826206-defa-407b-ad60-6ac19654ae72&file=Capture.PNG
Attached a staad model of the canopy .
Length 8.48 m
width 2.28 m
Code ASCE 7-05
Canopy location is at first floor level at 5.5 .which wind coefficients should be considered ?http://files.engineering.com/getfile.aspx?folder=87b1427a-26f0-4805-8c5e-7fb4f661dc42&file=Capture.PNG
I need to design a cantilever steel canopy , span 8.48m and width 2.2m
Plese help me to calculate wind load as per ASCE 7 , I calculated qh as 0.932kN/m2 .
How to choose wind pressure coefficients as per ASCE .??which figure should I refer for coefficients?
Please help , I am designing...
