Beam schedule along a grid line
Pick a level and a grid line — sizes, bars and stirrups span by span
metres · 0.014 m/px
— — orange dashed = buildable footprint after setbacks■ solid = column at a grid intersection, sized as designedhatched = bay not built on this storey — no slab, beam, column or loadX grid 1,2,3… · Y grid A,B,C…

The schedule is a design aid, not a bar bending schedule: laps, curtailment points, anchorage into columns and ductile detailing to IS 13920 must be added by the detailer. Top bars are shown continuous over the supports and bottom bars continuous through the span, which is the usual arrangement for a small residential frame.
