Notice there are several parameters available to control the suggested alternate

check ranges.
Design Rules – Concrete Rebar
In addition to controlling the size of your concrete members, RISA offers you the
ability to control what reinforcing and cover are used.
Next click on the Concrete Rebar tab.
These entries shown here will control the size and placement of the flexural and
shear reinforcement used in the design of our concrete beams and columns.
Click on the first cell in the Min Flex Bar column and use the drop down menu to
change the minimum bar size for our columns to a #6. Then click on the 3
rd
cell
in the Max Flex Bar colum and use the drop down menu to change the maximum
bar size for our beams to a #9.
Although rules for Concrete Rebar are given for each Design Rule that we have
created, these rebar entries will be ignored if they are applied to anything other
than concrete members.
