ACI 2-Span Beam Elevation Drawer (Figure 5 Style)

ACI Continuous Beam — 2-Span Elevation Figure 5 style (auto draw + BBS)

Spans & supports

L1 (clear span, m)

L2 (clear span, m)

Exterior column width (mm)

Interior column width (mm)

Beam depth h (mm)

Longitudinal bars

Bottom main db (mm)

No. of bottom bars

Extra bottom bars per span

Top bar dt (mm)

Top bars at exterior supports

Top bars at interior support

Stirrups (shear zones)

S1 near supports (mm)

S2 midspan (mm)

S1 zone length ratio (L×)

Stirrup dia (mm)
