Weight of reinforcement bars: worked example sheet in Equation Pad with typeset equations and results.

Example only. This sheet shows one way to set out the check. It is not endorsed by the bodies that publish the design codes and does not reproduce them. Check every clause, value and assumption against your own copy of the current edition of IS 456 before you use it, and have the result checked by a competent person. See the disclaimer.

The calculation, line by line

Every line below is typed into Equation Pad exactly as shown; the app typesets it, works out the value with its units and shows checks as TRUE or FALSE. Change any input and everything below it updates.

# Unit weight
rho_s := 7850 kg/m^3
w_10 := rho_s*pi/4*(10 mm)^2 = kg/m
w_16 := rho_s*pi/4*(16 mm)^2 = kg/m
w_20 := rho_s*pi/4*(20 mm)^2 = kg/m

# Beam
L := 6.4 m
W := 4*w_20*L + 2*w_16*L + 32*w_10*1.6 m = kg
