Minimum f'c Report

Minimum f'c Report

This report shows the minimum required concrete strength to satisfy the compressive stress requirements. The required concrete compressive strength for top and bottom of the section are reported in separate columns. This report is available for all cases.

The values for the initial case are based on initial concrete compressive strength (f'ci), and thus concrete allowable stress factors for the initial condition.

The Top and Bottom columns show the minimum required concrete strength to satisfy the concrete compressive stress requirements at the location.

In the left image I don't understand why the output is being flagged, (*): "provided is less than required". Isn't it similar to the right image from the CIP RC/PT girder help.

Isn't the value being reported the "minimum required concrete strength to satisfy the concrete compressive stress requirements"?

The initial concrete strength being used is f'ci = 5000 psi.

Thanks
