Dear RAM team,
From the linear analysis we get a predicted crack width (for the relevant load combination) based on the code formulation. And one of the things RAM does is to reinforce according to the code to keep that crack width.
When we run the Load History processor it develops a material nonlinear analysis where it iteratively cracks the slab until convergence is reached. Do we have access to the information about that real cracks against those predicted in the linear analysis?
-------------
Another question. We want to assess the crack width generated by shrinkage and temperature change. Is there a way to obtain it with RAM similar to CIRIA C660 guidelines?
Thanks, you are the best.
Regretfully we don't have a plot available for the expected crack widths after load history analysis, those are only available in section-analysis style plots for rule sets with detailed section analysis turned on.
I'm not familiar with the CIRIA C660 Early-age Thermal Crack Control in Concrete guide, but Ram Concept does not do anything special for changes in temperature so anything you could get out of the program would be a stretch of it's capabilities. Using load history analysis with various load steps and comparing the differences is what I have in mind.
