  • Modeling 2 way PT in the longitudinal direction and one-way mild in latitude direction

    I have a system with long-span PT girders in the longitudinal direction. Mild reinforced joists run perpendicular to these girders in the latitude direction. The slab is mild reinforced. I am trying to model these into RAM Concept and was wondering if…

  • Composite Joists in RSS

    Is there any option for specifying composite joists in RSS? The FloorVibe module had the option to use the SJI Composite Joist designations (i.e. ddCJxxx/xxx where dd is depth and xxx are the applicable loads). But I don't see any implementation of that…

  • How to account for joists in stiffness analysis in STAAD.Pro ?

  • RE: Equivalent steel section for joist girders

    The joists modeled in STAAD.Pro can be used for transferring gravity loads to the supporting members only and these are not accounted for in the stiffness analysis. If you would like to consider these members in the stiffness analysis, the only way would…

  • I need some help, do not know if what I'm doing okay , this is a school work. I do not know how to use the wizard section

    I'm doing homework, but I do not know how to use the wizard section , I want to do a double square tube to the top rope, but nothing happens, so I do equivalence of the tube. loads I'm using , if they are not correct, for example , I make linear loads…

  • RE: Joist design in Elements

    Thanks. The two logs are both indicating ASD when the 2005 code is selected, it looks like the problem is only with AISC 360-10 ASD. I'll report it (#370525)

  • Joist design in Elements

    Just FYI, when you run a design on a structure that uses open-web steel joists in RAM Elements 13.4.0.164, you may get a status message like the screenshot below indicating that Elements has designed the joists to a different design method than what was…

  • RE: RAM Structural Steel Joist Design

    In the SJI catalog, (Re: 43rd edition, page 123) the length of the joist is defined as L = (span - 0.33) in feet. Since we deal with the span in Ram Steel, we simply adjust the values in the table by the 0.33' value to get back to the SJI definition…

  • RAM SS Joists - Standard

    The model I've created is comprised solely of steel joists spanning between a combination of CMU walls (type: other) and steel W beams. When I create my joists and run the steel beam module, some joists show up as various joist sizes (10K1, 12K1, etc…

  • RAM SS What Beams and Joists Frame Into

    I am trying to use RAM Structural System to design an apartment building out of Steel and Wood. The wood beams are modeled as steel joists (I have custom joist tables set up for the wood beam members). The steel beams are modeled as steel beams. Both…

  • RE: Adding TJI Joist Table to Ram SS

    In our joist tables we expect the user to define a table of allowable live loads per joist length. The intent is that the allowable live load LLi in our nomenclature is the live load that produce deflection = Length/360. For each joist a section is…

  • New Joist Tool vs the older Bar Joist Modeling Tool

    Running AECOsim Building Designer SELECTseries 5 (08.11.09.747) New Joist Tool vs. the Old Bar Joist Modeling Tool The new joist program although it may work well with ISM (I haven’t tested this yet) doesn’t offer the level of detail needed for…

  • RAM Steel Joists [FAQ]

    Applies To Product(s): RAM Structural System; Ram Steel Version(s): Any Area: Design, Tables Why is the reported joist allowable load less than the value in the SJI catalog? In the SJI Catalog…

  • Joist equivalent load calculation

    I am a new RAM Structural user, but was a joist engineer for over 10 years, and I am trying to figure out the nonuniform load calculation method for joists in Ram Structural. I have a case of dead+base snow+snow drift that I am checking, and the joist…
