• RAM Concept Load History Deflection Analysis Results Table

    RAM Concept’s load history deflection calculations are complex due to the many non-linear behaviors that are considered (see Load History Deflection Calculations for more information). When unexpected results are obtained, it can be difficult to verify…

  • RAM Concept Load History Deflection Calculations

    Long-term concrete deflections are difficult to predict due to the influence of several non-linear behaviors that complicate the calculations. Historically, design engineers have relied on approximate methods, like deflection multipliers, to simplify…

  • 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…
