Hi Karl,
As per AS3600 Amendment #2, ratio of k3(7 days)/k3(28 days) = 1.326.
Design creep coefficient as per AS3600 after 30 years for a 200 thk. interior 40 Mpa slab, loaded at 7 days = 1.326 x 2.41(Table 3.1.8.3) = 3.20.
For input in Ramconcept we need to add 1. So Creep factor to input in Ram would be 3.2+1 = 4.2 as apposed to 3.35 of ACI.
How come there is such a huge difference between AS3600 & ACI creep factors for inputting in Ram?
