• RC slab deflections

    Hi all, Deflection results from the RAM Concept model don't seem to be correct. I've spent hours on this and cant figure out why this is the case. Any input is appreciated. For example: - 200 slab, 10.4m x 8m bay - only 16 mm long term strip deflection…

  • RAM Concept - Load History Deflections Not Converging

    Hi, I have two RAM Concept suspended slab models which will not converge when running the load history deflections and I am at a loss as too why. Below is the warning provided in the Load History Calc Log: WARNING: An error has been found while…

  • RAM Concept Deflections for Service Load Combination

    Howdy, Are the deflections reported in the Max and Min Deflection Plans under a given load combination layer, say Service LC: D+L, based on cross-section effective moment of inertia? Can RAM Concept report max and min deflections based on cross-section…

  • how to get the loadings details in report????

    I have got my report, but there is no loading details like dead load, Wind loads and all... In report settings i have added Loadings, but its not showing.... Wt to do???? i want to see other load details. How to get that details?

  • RC wall modelling in RAM Concept

    Hi there, I have some doubts modelling RC walls in the RAM Concept. Having the walls as shear wall which would restrain the slab improves the deflection in the slab, other properties are fixed near and compressible. I also have another opinion which…

  • RE: Creep coefficient Eurocode

    The creep model used in Ram Concept for Load History deflections is based on ACI 209R-92. Refer to the program manual section 67.3.2 for some general information. For further reading see this wiki post: RAM Concept Load History Calc Options TN …

  • RE: RAM ECR parameters

    A colleague who is more familiar with the AS 3600 code offered this help. AS 3600 breaks down total shrinkage into autogenous shrinkage and drying shrinkage, whereas Concept only has a single value for shrinkage that represents the combination. I think…

  • RE: Long Term Deflections for ACI318 in RAM Concept

    The L.T. Deflection Plan is no longer a standard plan, since load history deflections are the recommended method for long term deflections. However, you can create a new plan and plot the strip-based L.T. Deflections as follows: 1. Click on the Layers…

  • RE: Load History Deflections in Concept to British or EU standards

    I'm sure lots of engineers have used Concept for this purpose. I assume you are using Load History analysis. Alt Envelope factors are not used in Load History analysis, only the standard load (and pattern is used). The program manual, section 67.1…

  • RAM Concept Load History Deflections

    We are currently working on a RC garage model (11” slab thickness, max span ≈34’). We are noticing that our load history deflections are much larger than we are expecting. When we run load history deflections we get a Final Instantaneous Deflection…

  • RAM Concept Long Term Deflections

    Hi, I am new to RAM Concept. I have created my model and have gotten deflections for my load cases. I was wondering if there was a way to get the long term deflections as well? And if so how would I go about doing this?

  • Long Term Deflections RAM Concept

    When looking at the long term deflections in RAM Concept, not using the Long Term Load History calculations. I check the Service Design rule set and under Section analysis, I check the selector called Long Term Deflection, This appears to take the elastic…

  • RAM Concept Shrinkage Restraint

    So from reading the RAM Concept Load History Calc Options Technote it appears that the shrinkage restraint will just adjust the cracking values of the concrete floor for long term load history calculations is this correct? For instance if I have a floor…
