- B9 (확대기초철근 (1).md §9): H16 with the 135° stirrup hook, on the odd grid (i_W = 1, 5, …), 16 rows, 20 per row (even rows start at i_L 1, odd at 3), 320 bars, length l_v 1750 + 2 × 189 ≈ 2128. - The rebar summary now lists B9; the alert about B9 is gone. Positions and hooks are the document's proposed rules (Q-B18, Q-B19), noted on the row. - Tests: the document's B9 values; P1 summary has 320 and only the splice alert. - Not verified in a browser.
