Rcc Roof Slab Steel Calculation

Beside this the slab has following information for main bars length of on rod 7 meter diameter 12 mm.

Rcc roof slab steel calculation.

Let us take an example of a slab. Percentage of steel in column 1 to 5. Following are the steps to calculate the quantity of steel for rcc slab 1. Number of main bars ly spacing 1 4000 150 1 27 nos.

Number of required bars formula length of slab spacing 1. Weight of steel 0 0081 x 7850. Let the shorter span has provided the main rod and longer span has provided distribution rod. Let the shorter span has provided the main rod and longer span has provided distribution rod.

Unit weight steel 7850 kg m 3. 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. So volume of steel 3 100 x 0 27. Thickness of slab 150 mm.

One way slab bar bending schedule calculation. Height h 3 m. Q the length and breadth of slab is 10 meter and 7 meter respectively. Count the number.

Numecal for rcc roof slab steel calculation. List down all the shapes of bars from the drawing. First find number of rods required for main reinforcement and distribution. 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.
