Rcc Roof Slab Steel Calculation

Numecal for rcc roof slab steel calculation q the length and breadth of slab is 10 meter and 7 meter respectively.

Rcc roof slab steel calculation.

Numecal for rcc roof slab steel calculation. Thickness of slab 150 mm. Let the shorter span has provided the main rod and longer span has provided distribution rod. Percentage of steel in column 1 to 5.

Number of main bars ly spacing 1 4000 150 1 27 nos. 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. Following are the steps to calculate the quantity of steel for rcc slab 1. Height h 3 m.

Number of required bars formula length of slab spacing 1. Beside this the slab has following information for main bars length of on rod 7 meter diameter 12 mm. First find number of rods required for main reinforcement and distribution. 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.

Count the number. List down all the shapes of bars from the drawing. We take 3 of steel in column. So volume of steel 3 100 x 0 27.

Unit weight steel 7850 kg m 3. Let us take an example of a slab. Lateral dimension 0 3m x0 3 m. Weight of steel 0 0081 x 7850.
