For a beam of span 5m and cross section 230mm*500mm , is reinforced with 2-12Φ at top and 4-16 Φ at bottom out of which two bars are bent up and stirrups 8 Φ @ 150c/c. Calculate the quantity and cost of Materials.(Steel, cement, sand , aggregates).

Assume clear cover of 40mm

1) Length of top straight bars

L= Length of beam – 2×cover + (2×9×d)

=5000 - (2×40) + (2×9×12)

=5135m

2) Length of bottom straight bars

L= Length of beam – 2×cover + (2×9×d)

=5000 - (2×40) + (2×9×16)

=55208m

3) Length of bent up …
