Rcc Roof Slab Steel Calculation

To get a rough idea for the construction cost you can get a hint from this formula however in general it is assumed that to construct an rcc roof slab the approx cost would be rs 180 to 200 00 per sq ft where the cost for steel labor shuttering and material is included.

Rcc roof slab steel calculation.

Thickness of slab 150 mm. Following are the steps to calculate the quantity of steel for rcc slab 1. Percentage of steel in column 1 to 5. Numecal for rcc roof slab steel calculation.

We take 3 of steel in column. Number of required bars formula length of slab spacing 1. Let us take an example of a slab. Let the shorter span has provided the main rod and longer span has provided distribution rod.

Height h 3 m. Unit weight steel 7850 kg m 3. So volume of steel 3 100 x 0 27. Let the shorter span has provided the main rod and longer span has provided distribution rod.

First find number of rods required for main reinforcement and distribution. One way slab bar bending schedule calculation. Lateral dimension 0 3m x0 3 m. Number of main bars ly spacing 1 4000 150 1 27 nos.

Count the number. Prepare a bar bending schedule in order to classify different shapes of bars bent up bar straight anchor bar eos bar curtail bar etc and diameters. Beside this the slab has following information for main bars length of on rod 7 meter diameter 12 mm. Weight of steel 0 0081 x 7850.
