  • Using option "5L" in the "CODE" command line

    I'm just wondering why in the "CODE" command line in SACS (14.2.0.1), non-tubular code option of "5L" which refers to "AISC 15th 2016" doesn't work properly and it doesn't show any code check for non-tubular sections at the end. If "5L" is replaced with…
  • SACS Classification section (compact, noncompact, slender) in according with AISC.

    Hi there. Could anybody explain me why SACS define "Noncompact" section class for PG1200x500x12x25. We have flange W-T ratio (b/tf) which equals 10.0 in according with AISC 1989, SACS has to define this flange as slender. Could anybody correct me…
  • SACS | Lateral Torsional Buckling of Unsymmetrical Plate Girders with AISC 14th and AISC 15th

    Hi, I am writing because I need to verify Unsymmetrical Plate Girders with AISC 2010 and I do not why I have very high Unity Ratio under Lateral Torsional Buckling when I increase the Upper Flange width in the picture you can see the same beam…
  • How to override material factor for Non-tubular member for ALS condition when using IS\AISC code-checked

    Dear Sir, I used ISO code in combination with AISC 360-10 for member code check. "IS" is selected in Option card. CODE IS and RFLRFD are also provided in my input file. Both ULS and ALS load combination are included in the same SACS file. I…

    SACS How can I display member Max Combined UC (Axial + Bending) disregarding Shear Unity Ratio (AISC)? I use SACS daily since 2012 to analyse offshore steel structures, with latest AISC/API, during installation and transportation. At the moment I have…
  • SPAN & Physical Member commands in SACS

    Hello all, There are some ambiguities for me about the use of SPAN and PHYSICAL MEMBER commands in SACS. Consider the following simple senario: Imagine we have a main deck beam (say HEB600), on top of which stringer beams( say IPE200) are running…
