How is a shrinkage considered in the calculation with RF-CONCRETE Deflect?

Answer

In the analytical deformation analysis with RF-CONCRETE Deflect, shrinkage of the concrete is considered by means of an additional curvature.


It should also be noted that an asymmetrical distribution of reinforcement on the top and bottom of the surface leads to an additional curvature because a higher reinforcement area on one of both sides would affect shrinkage more than in opposite directions. This results in an additional curvature of the surface.

Despite the increased reinforcement, this effect may result - depending on the structure - in no reduction of the deformation from the calculation.

You can find additional information about this in the manual RF-CONCRETE Surfaces in Chapter 2.7.5.2.
