• RE: Extract different stresses from staad post processing menu

    You are correct. A +ve value of Bend-Z represents bending compression and -ve value represents bending tension. The Axial column in the same table represents both axial tension/compression. A positive value represents compression and negative value…

  • RE: RAM Frame Story Shear with Multiple Diaphragms

    When the diaphragm is pseudo-flexible, the location of the graphic for the diaphragm shear is largely irrelevant. This wiki indicates that it's somewhere near the geometric center. If you look at the building story shear report, you'll see 4 lines in…

  • Does STAAD show maximum shear & moments in the DECK or in the GIRDERS?

    We have modeled a two-span continuous bridge (50' spans), 6 girders in the cross section (60' bridge width). We are loading with truck & tandem loadings per AASHTO bridge design specifications. When analyzing for maximum positive & negative shears and…

  • RE: Bent Plates in RAM Connection

    I think the situation here is that AISC 360-10, Table 10-9 is used in the case of a single plate connection only. We opted to only implement this for shear tabs since it's within that specific section of Chapter 10, but it would be a good question for…

  • RE: Ram Concept- Shear Reinforcement

    If you look closely at the section audit for a section from each case and compare them side by side it's a little easier to tell what is most significant. Below is a table of just a few lines from the audit to help you, ultimately is a small change in…

  • RE: Vertical Shear Contour Plot in RAM Concept

    I would normally recommend plotting Slab - Shear - (Mid depth) Max (and Min) for this, though you will get a warning like this for any Rule Set: --------------------------- Slab Plot Accuracy --------------------------- The selected slab plot may…

  • SHEAR in RAM

    Dear RAM Concept crew, I would like to know how the shear design is done (not punching shear). I am using Eurocode 2. My question is: where is it checking the shear capacity? According to the EC it should be done at “d” distance from the edge of the…

  • STAAD shear calculation error for AISC 360-10

    Hi All, I have noticed that STAAD incorrectly calculates the shear capacity for a member. Specifically, it uses a VERY large shear area (overstated by a factor of 2!). Here is the output for an Australian 250UC72.9: INTERMEDIATE: Aw: Cv: Kv: h/tw: Vn…

  • User Shear Bars in RAM Concept

    I'm (still) working on analyzing my existing waffle slab. I've worked out a lot of the kinks, but the user shear bars are still throwing me for a loop. I assign user shear bars adjacent to the column drop cap like so: The result once they get…

  • RE: Waffle Slab in RAM Concept

    I think the Concept analysis is limited to a single core which might account for the limited CPU resources it claims. Using the 64 bit version and he Pardiso solver are good ideas. The other things I can think of to possibly speed things up are to: …

  • RE: RAM CONCEPT: Shear reo in slabs according to AS3600-2009

    You might find the section design plot for "Shear Density" to be informative. In the case os your right middle strip, the shear demand is indeed quite small, but a plot of Strength Design - Shear density indicates ties are required at several stations…

  • RAM Concept Shear + Torsion and Tabular Input

    Hello again. I was adding some user shear reinforcement to a model recently (hurray for this being a feature now), and had some things happened that piqued my interest. I started digging around in the audit report to better understand how Concept is…

  • RE: RAM Concept Reinforcement Detailed Bars Perspective

    On the design status layers, the tick marks for the shear bars are a bit symbolic. They are typically placed along the span segment line and spaced based on the design. See manual section 29.5.4 "Shear reinforcement" for details on this kind of output…
