How to model a Flat steel bar 150 wide x 10 Thk x 1000 Long and be able to design and get unity ratio for the member.
Thanks
To begin with, STAAD.Pro does not design flat bars. The only way to get a design out of STAAD for these type of sections is to define these as User table General Sections ( using menu option Tools > Create User table > New table and choosing section type as General ). You would need to enter the appropriate properties of the section like Cross Sectional Area, Moment of Inertia, Section Modulii and others. STAAD would then design the user table general section following rules applicable for wide flanges and generate unity ratios.
Dear Sye,
Is it not possible to define the flat bars with YD and ZD?
Yes you can but the only issue with that is, these are treated by STAAD as prismatic sections and hence not designed. If you do not need a design, you sure can use YD and ZD.
Hello ..I face the same problem.. I need to design a FLAT BAR with section (200x12) according to the AISC 360-10. Unfortunately, once i presented the results the VNZ=297 kN which is totally wrong cuz it must be:
Vn=0.6*Fy*Aw*Cv = 0.6x275x(200x12)x1.00=396000 N=396 kN (G2-1)
0.9*Vn = 0.9*396 = 356 kN
Also, the VNY also wasn't the same as VNZ
I did a parallel model using Autodesk ROBOT structural analysis professional and the results were 100% correct.
Could you pls guide me on how to fix this problem using STAAD Pro
/the attached images explain what I did and the results I got/
