Material Concrete01

Hi all,
I am running the analysis of a 6 storey RC structure. Analysis runs up to 12cm displacement with 12Mpa concrete and the curve is a straight line like in linear behavior. When I use 20Mpa concrete dispControl wont run a single iteration. Does anyone have any idea what going on with this?
Cheers

I suggest you do some single degree of freedom analysis with a truss element looking at stress-strain responses of the materials to ensure you have the parameters correct.

If o.k. then your analysis script needs some modification, i.e. smaller steps or alternative algorithms.
