  • RAM SS Concrete Beam Design Criteria

    I am having trouble telling RAM where to put a secondary layer of longitudinal reinforcement. If I assign a different value to 2 Layers in the Beam Criteria it appears to assign my values under 2 Layers just to my top bars. I have attached a screen cap…

  • Concrete design tab in 21.00.02.30 and units of output viewer

    In the latest STAAD connect edition, why does the concrete design tab not show up in the properties of any selected beam although I have assigned concrete design command? It's easier to see the number and sizes of bars required rather than reading the…

  • Does STAAD design for CONCRETE SPECIAL MOMENT FRAME as per ACI 318M-11 ??

    Hi, 1. Does STAAD take into account the ductile detailing provisions of CHAPTER 21 of ACI 318M-11, while arriving at the reinforcement area and stirrup area ?? 3. If those provisions are available, how does STAAD identify a SMRF or IMRF or OMRF in…

  • RAM Concrete Node Tolerance Error

    Hi, I'm running a model of a concrete podium structure and seem to be running into a "node tolerance error". The exact text is: "Tolerance error at coordinates (x,y,z). Check if all members at this coordinate are aligned." The given coordinates lie…

  • Volume of concrete and steel.

    Hi In my STAAD.Pro output result the volume of concrete and steel is not there. Please help me. Thanku

  • Euro code concrete design in Staad SS6

    Dear Support, We are using Eurocodes for our project. Please note that for STAAD select series 6, Eurocodes for concrete design are not implemented ; please see below image. Whereas they are implemented select series 5. See below image. (EC2 stands…

  • RE: Deflection of a concrete beam as per ACI

    No it does not use the effective moment of inertia. For the analysis, it uses the gross moment of inertia multiplied by any reduction factors that the user may specify through the Property Reduction Factors. Users of course can directly specify moment…

  • RE: RAM Elements Concrete Wall Design Module - ACI 318 update

    Regretfully no change I'm afraid. We still need to release an update to the program with newer codes and it's still months away. Re: Enhancement Request #699960

  • RE: Deflection Parameter for RCC Beam

    The deflection parameters like DFF, DJ1, DJ2 which are available for steel design are not there for concrete design as most concrete codes require you to provide a member or a slab of a certain depth so that the span/depth is within a certain limit. For…

    A good place to start would be to go to the Help > Content > Getting Started and Tutorials > Tutorial 2 which would walk you through the steps of modeling concrete frames. Tutorial 3 explains how to model concrete slabs. In addition, there are couple…

  • RE: Reinforced Concrete Design

    A good place to start would be to go to the Help > Content > Getting Started and Tutorials > Tutorial 2. Reinforcements are not modeled. You can model concrete cross sections and then the software can tell you the reinforcement required as part of the…

    Please check the program Help - Chapter 19 RC Design and Detailing for instructions and specifics.

  • RE: Assigning Beams to be a Single Continuous Beam

    As far as the analysis is concerned, the continuity of the member is still maintained even if it is split into segments. As far as concrete design is concerned, most codes recommend carrying out a second order analysis like PDELTA to account for slenderness…

  • RE: Analysis of existing concrete building structure

    Hyunjin Kim : Sorry for the delay in responding to the original query. STAAD.Pro does not account for reinforcement when it comes to the stiffness analysis. It calculates the stiffness ( axial, moment, shear etc. ) based on the gross sectional dimensions…

  • RE: Why the steel at mid section of a beam the steel at top fiber is more than bottom fiber?

    As you know the moments due to seismic will be minimal or zero close to the midspan. So midspan moments would usually come from gravity loads and so one would expect the bottom moments to be higher at midspan. Here are a couple of things you may want…
