Modelling time dependent concrete properties in ABAQUS

I am
carrying out a non-linear analysis of a concrete section subjected to construction
loading. I am looking to model the time-dependent effects of the material
properties as well as creep and shrinkage properties of concrete. In the ABAQUS
manual it states the General Static procedure
cannot be used to model time dependent effects. Naturally the Riks Method would be ideal to account of
the non-linear effects however it doesn’t allow for the use of multiple steps in
the analysis which is necessary to model the various stages of construction
loading. Does anyone have any advice on what would be the the correct analysis
step to implement?
