h2. How is shrinkage modeled?

*Answer:* Please see the [Bridge shrinkage example|tp:Bridge shrinkage example] tutorial for a demonstration of shrinkage application.


h2. During shrinkage analysis, why are there no reactions?

*Extended Question:* I am using a nonlinear long-term cracked-analysis load case to model shrinkage behavior. Why are there no reactions?

*Answer:* To perform nonlinear [cracked-section analysis|safe:Cracked-section analysis], a Dead [load case|kb:Load case] must be applied to the slab surface to induce deflections and reactions.
