ypshim a2317caf6c feat(rebar): add downward 90° hooks (135 mm) to P6 crossties in 3D rebar model 2026-10-22 17:45:22 +09:00
ypshimandClaude Haiku 5.5 b962cf1a1c feat(core): bearing-block drawing check and coping rebar C3 (plan C2·C3)
- Drawing check (spec §6.3): an integrated 2500 × 1200 block gives 18@125 = 2250
  along (ends 50 + 75) and 7@125 = 875 across (ends 162.5).
- C3 coping rebar, from RAG/코핑철근.md (2026-10-22 final):
  - C10: 9 bars @300 at 4800–7200 (k_max 4, beyond the Level edge).
  - C9 / C11: 18 bars each @250 outward, ends at 300 and 11700 (end gap 300).
  - Refuses a coping too short for C9 (RB-K01).
  - Side bars C12 5 rows / C13 2 rows at the 42.538 break; C14 38 bars;
    C15 11 bars, C16 22 bars.
- spec §6.4 is older than 코핑철근.md (C10/C9/C11 layout, C12 row count, C14
  dimensions). This follows the final document; spec §6.4 needs an update.
- Not yet: C1–C8 main bars (shape and lengths), the C12/C13 bar lengths and
  shapes, the drawing check of the coping sheet, and the ③ screen.

ypshimandClaude Haiku 5.5 daf78d0586 feat(core): rebar common rules (plan C1) and bearing-block bars (plan C2)
- C1: development length l_d = 0.6·d_b·fy/(λ√fck), splice 1.3·l_d, standard
  hooks (main 90°, tie 90°, stirrup 135° as written in the spec). fck 27 and
  fy 400/500 are marked as assumed values (I02).
- C2: bearing-block bars, one block per bearing (배치 분리). Bars S1 and S2 at
  @125 with 8 bars per 1200 mm side (7 gaps = 875, ends 162.5), 2500 mm long,
  coping embedment from the block height (pad included, Q16 결정).
- Tests: development and splice lengths; hook table limits; embedment 600 /
  550 / 619.1 / 569.1; P1 has 80 bars each of S1 and S2 over 10 blocks.
- Not yet: the ③ screen and the drawing check against the bearing-block drawing.
