D is an input on the column card (default 2000 mm). The 3D column, the piles of a cast-in pier and the column rebar follow it;
n_div stays 46. Three checks run on each regenerate and appear in 알림: D below the Level width (2100), D + 2c within the
coping width, and the 주철근 arc spacing ≥ max(1.5·d_b, 40). Spec §5.2 records the rule (approved 2026-10-23).

The coping middle level is (Level underside + step top)/2. P3's top and P6's upper limit are this level, and e_top is the
step top minus it (P1: 1322, replacing the 1623 reverse-engineered value). On P1 P3 goes from 38 to 39 ties and P6 stays at
8 levels. With taper h2 = 3000 the middle level is 13275: P3 37 ties, P6 8 levels (32 bars), e_top 2072.

e_P1 is no longer an input: P1 top = C3 (lowest coping top − 127 − 2·57.2 = 43.170) − 100 = 43.070, so e_P1 = step top −
43.070 = 485 mm. The P1 top moves from 15147 to 14862 mm; the top piece shortens by 285 mm. Couplers are placed at k·3000
with at least 2500 mm below the P1 top (a value to confirm). On P1 the coupler count stays at four (3, 6, 9, 12 m). P2 and
the tie top do not change.

Hc = Level underside − footing top, and h_cop = step top at the column centre − Level underside. P1 gives 12703 and 2644,
unchanged. With taper h2 = 3000 the Level underside moves down, so Hc = 11203 and the P2 top (Level underside + l_d)
moves to 13039, while the P1 top stays at the step top (15147). The 3D and the 철근표 use the same heights.

fyH and fyS become a grade per prefix (D · H · S), chosen from SD300 · SD400 · SD500. The defaults are the P1 values, so
the P1 results do not change. Each bar takes its grade from its 규격 (fyOf). The 철근표 has a 강도 column. Older files
that stored fyH / fyS are read into the grade map. Only fck is still an assumed value (I02). Approved 2026-10-23.

- 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.

- A P4 is deleted when |z_P4 − z_bar| < (d_P4 + d_bar)/2 against B5 and B1
(the 확대기초 top layer, from the 상면). B11/B12 are not checked (Q-C9 무시).
- The P6 crossties start from the first kept P4.
- Tests: the document's example keeps all 8; B5 moved to −70 deletes the P4 at
−60; a P4 just outside the limit is kept.

- Coping: C9/C10 lower U = 1740 + 2h with h linear along the slope and 2300 on

C13 11746, C14 3447.5, C15 3852, C16 4070.
- Column: P3 = C_t + 1.3·l_d(H19) lap (추천안 for Q-C6, lap 1146.6), P5 = C_t.
- Footing: B2 13646 is split into two pieces at a splice with 1.3·l_d(S25,
SD500) (추천안 for Q-B6), piece ≈ 7776 each.
- Not done: C9/C11 cap (삿갓) lengths (Q-K5 open), P1/P2 per-line pieces.
- Tests against the document values; P1 summary updated.
- Not verified in a browser.

- Nominal bar diameters (H29 28.6, S32 31.8, …) as used by the documents. With
them, C7/C8 l_s = 1.3·l_d(28.6, fck 27) = 1717.6, which is the document's 1717.
- C1–C8 (코핑철근.md §5): width layout 127 · 110.5 · 21@125 · 110.5 · 127 with 24
bars (12 + 12); heights 43.284 / 43.227 / 43.170; top bar lengths 12744 /

- C4 (기둥철근.md): P1 r 875 and P2 r 843.2; couplers P1 +3/6/9/12 m, P2 +150;
230 + 230 main pieces and 368 couplers; tie radius 900.45; P3 38 at @300 from
2.340; P5 19 at @120; P4 8 at @120 from −0.060; P6 8 levels × 4 = 32, length

- Not yet: C4 interference checks (P4 vs B11, Q-C9), bar lengths of P3/P5/P4
and coupler shapes, the coping/column drawing checks, and the ③ screen.
