- Material {fck, fyH, fyS}, defaults 27 / 400 / 500 as assumed values (I02).
The rebar calculations take the material: the C7/C8 splice, the P2 development
length, the P3 lap, and the B2 split use it instead of fixed numbers.
- ③ screen: 공통 설정 inputs with a note that the defaults are assumed (I02).
- Project file stores the material as an optional field; older files open with
the defaults.
- Tests: fck 27 → 35 shortens the laps by √(27/35); the C7 piece follows fck;
a non-default fy drops I02; the file round trip.
