RAM Concept - Creep Coefficient & Shrinkage Report
Hello,
When using RAM Concept to calculate the creep coefficient and shrinkage strains, is there some way to report the values after a load history analysis?
Ram Concept Load History Deflections
Can someone clarify/explain how Ram Concepts determines the Load History based on the Load Combinations chosen in the Load History steps?
I ran the Load History and looked at the deflections for the "Final Instantaneous" step and got 1.28" of deflection…
AS3600:2018 creep factor
Hello all,
Given that the new update of RAM Concept incorporates AS3600:2018 I think that the following becomes relevant. When determining the creep factor AS3600:2018 has an additional coefficient - k_6, which is intended to account for non-linear…
How to apply concrete creep reduction factor on slab when calculating temperature loading actions
Hi,
I am trying to calculate the temperature load effect on a concrete slab. However, the stress resulted is too large. Refer to other software, there will be a reduction factor considering the concrete creep at 0,3~0.5. However, I didnt find any place…
RE: final displacement
Long term deflection is not calculated. You can account for cracking of concrete. Please refer to the last paragraph in the wiki below
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.

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…

I'm paraphrasing something from the Ram Concept development manager, but this seems to fit your situation:
Question: " Could you please confirm what we would be using as the value for Creep Factor in the Calc Options menu input. We design to AS3600…
