Hi,
In defining the layered section, How is the thickness of the reinforcement bars calculated (0.2403,0.2356) in the following manual example?

#middle region
# material absolute thickness angle(steel) material tag
##cover 12.5 4
##d=6transverse 0.2403 0 11
##d=6longitudinal 0.2356 90 10
##core 49.5241 4
