    RAM Concept - External Shrinkage Restraint for Multi-Story Concrete Structures

    The purpose of this article is to establish an appropriate Shrinkage Restraint percentage to use for a typical intermediate concrete floor in a multi-story structure. The calculations demonstrate how construction sequence and varying shrinkage rates of…

  • 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…

  • 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?

  • 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 Concrete Beam - Effective Depth used for Deflection Calculations when Reinforcing Continuous at Beam Depth Change

    Your images did not come through, but if I understand correctly, you have two consecutive spans that are different depth beams with continuous top bars across the support, but the d value used in the deflection checks is less than expected. Splicing…

  • 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…

  • 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…
