The following are calculated internally:
- ElementLength
-
- individual-element length
- fY_ksi
-
- yield strength of the longitudinal reinforcement in the section in ksi (if not specified in section = 60ksi)
- Db
-
- diameter of longitudinal reinforcement in the section (if not specified in section = 1.0)
- fpc_ksi
-
- nominal compressive strength of concrete in section (if not specified in section = 4.0 ksi)
- ElementDepth
-
- depth of cross section (if not specified in section = 0.)
