• Buckling Factor for Simple Pinned Column

    Hi, I used the verification example for the buckling factors for determining the critical buckling loads for a simple column (pinned pinned). However I get different results every time I run them. How do I ensure that the values I get are the…

  • Plate bucking checks for BCW single plate shear connections

    It appears that RAM Connection (v13 update 4) does not check the plate buckling limit state (analogous to the coped beam web buckling check) for extended shear tab beam to column web shear connections per the provisions of chapter 9 of the AISC steel…

  • 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…

  • Modeling of Built Up / Tapering Columns

    Is there a guide as to how to model a built up column in Ram Elements with various section properties across its height? I'm looking to design a column that has changing section properties across its height. It would not be linearly tapered but more…

  • Buckling Mode Shapes & results

    I have Arch Structure, Which i have modelled using straight Small beams (To avoid Curved Beam). Two Main Arches are inter connected with internal Cross bracings. I have applied Wind loads on Nodes + Usual Dead Loads. Command " PERFORM BUCKLING ANALYSIS…

  • Buckling Problem - Cannot decide what effective length factor (K) values to input to my model, can you help?

    I'm working on a 4 columned structural mast and I made a model of it on Sap2000. And Sap2000 gave me great amounts of K factor values, such as 5,7~8,0 That sounds creepy! This tower has 4 columns and spacing is about 2m x 1.2m between. Software doesn…

  • RE: Buckling Analysis in Staad

    You DO NOT need a PDELTA analysis before the BUCKLING ANALYSIS command. These are unrelated analysis types and should NOT be used together. The buckling factors would be printed as part of the analysis output file (ANL file) for each case and you do not…

  • RE: Buckling verification problem

    There are verification examples provided within the software installation folder marked below C:\SProV8i SS6\STAAD\Examp\Buckling

  • RE: PLATE GIRDER PROPERTIES

    Post buckling behavior cannot be simulated using the buckling analysis in STAAD.Pro. Nonlinear Analysis would definitely be a better option to use if you are trying to account for the changes in stiffness due to deformed geometry and stress stiffening…

  • RE: PLATE GIRDER PROPERTIES

    For carrying out a buckling analysis for the load case you have defined, you need to replace the PERFORM ANALYSIS command by the buckling analysis command PERFORM BUCKLING ANALYSIS MAXSTEP 15. Also noted that in your user table definitions you defined…

  • RE: column imperfection buckling check

    Since you need to know the buckling load, you simply need to do a buckling analysis. From the imperfection load you defined, it seems like you want to check for an out of plumbness of 32.1/200 m = 0.1605m. You can either apply this as an equivalent lateral…

  • Eurocode EN 1993-1-1:2005: code check using resultant forces

    Hello, I'm looking into the code checking of a circular cross-section (class 1) using the Eurocode EN 1993-1-1:2005, and have some questions regarding how Staad.Pro does the checks: 1) For clause 6.2.6 (shear) there is given two utilisations, one…

  • buckling check as per En1993-1-5

    hi, if i want to check a grider panel of 1mx 1m plate as per EN1993-1-5 code can i able to do it? , i have checked with plate elements, it is giving the stress only in the plate design output, how to check the stability of plate under buckling as per…
