The following annotations apply to the output:

LEVEL

Serial number of bar level which may contain one or more bar group

HEIGHT

Height of bar level from the bottom of beam

BAR INFO

Reinforcement bar information specifying number of bars and bar size

FROM

Distance from the start of the beam to the start of the reinforcement bar

TO

Distance from the start of the beam to the end of the reinforcement bar

ANCHOR(STA/END)

States whether anchorage, either a hook or continuation, is needed at start (STA) or at the end

ROW

Actually required flexural reinforcement (As/bd) where b = width of cross section (ZD for rectangular and square section) and d = effective depth of cross section (YD - distance from extreme tension fiber to the c.g. of main reinforcement).

ROWMN

Minimum required flexural reinforcement (Amin/bd)

ROWMX

Maximum allowable flexural reinforcement (Amax/bd)

SPACING

Distance between centers of adjacent bars of main reinforcement

Vu

Factored shear force at section

Vc

Nominal shear strength provided by concrete

Vs

Nominal shear strength provided by shear reinforcement

Tu

Factored torsional moment at section

Tc

Nominal torsional moment strength provided by concrete

Ts

Nominal torsional moment strength provided by torsion reinforcement
