• Why IS Code 800-2007 LSD fails Ratio INFINITY, while AISC 360-10 ASD passed Beam with Ratio 0.44? Taper beam

    1) Design check by IS Code 800-2007 LSD fails gives result of Bending Ratio = “INFINITY”, which passes with AISC 360-10 ASD Ratio 0.44! Also IS 800 code output does not give any ratio in both major, minor axis! 2) Is this 12 mm Flange thickness is critical…
  • Is UNB/UNT/UNL linked to effective length factors Ky and Kz in STAADPRO?

    Hi all, I was wondering if anyone could provide some clarity on the use of UNL (UNB/UNT) in the case of cantilever members. What I know so far is that Ky and Kz would have some typical factor of 2 or 2.1 for cantilever members, and this impacts the…
  • Ram Concrete Column Buckling

    How is RAM using the nomograph to calculate the K factor for a non-sway column that is braced by the slab? Under the "bracing criteria" if I keep the assignment as "slab braces the column" but I don't have a beam framing directly into the column in that…
  • RE: QUESTIONS! HOW I CAN CALCULATE THE PARAMETER KX ,KY AND KZ FOR A COLUMN IN A STRUCTURE OF STEEL

    A couple of points. If you are using the AISC 360-10 then you should use the DIRECT ANALYSIS which is the analysis method which is most generic and applicable for all structures. Another great advantage of using DIRECT ANALYSIS is that you can use K=1…
