Which is best mm bar used for 1, 2 and 3 storey building

Which is best mm bar used for 1, 2 and 3 storey building, hi guys in this article we know about full reinforcement details and best mm bar used for footing, column, plinth beam, floor beam and RCC slab for (G+0) 1 storey/G+1 (2storey)/ G+2/3 storey building and also know about diameter of iron rod and their number for footing, column, beam and slab.

People might be in confusion which type of reinforcement/ steel bar is best for using in RCC structural member like footing, column, beam and slab of your residential and commercial building. In this article we talk about use of different size of steel bar in different RCC structure for 1 storey (G+0), 2 storey (G+1) and 3 storey (G+2)building.

Sizes of reinforcement/steel bar used in different RCC member are determined on the basis of architectural drawing & designing for 1, 2 and 3 storey residential building. If you want to design for residential building structure and where the height of building is not more than 30m and spacing of columns are 3m to 5m, not more than 5m, you can do it by using thumb rule.

When we draw design for rcc structure for residential 1st storey (G+0), 2 storey (G+1) and 3 storey (G+2) building you have to also check the,live load, soil type, dead load, bearing capacity of soil, vertical load, horizontal load, slenderness ratio, deflection of beam etc. as per I.S. Code guidelines.

Which is best mm bar used for 1, 2 and 3 storey building

According to general thumb rule, we will assume a structure of G+0/1 storey/ground floor/one floor residential building, using standard 9″ thick walls, the best mm bar used for 1 storey/G+0 building, we should use steel bar of 10mm dia for footing, 12mm dia of steel bar used for column, combination of 10mm & 12mm dia of steel bar used for beam and combination of 10mm & 8mm steel bar used for rcc roof slab casting.

According to general thumb rule, we will assume a structure of G+1/2 storey/two floor residential building, using standard 9″ thick walls, the best mm bar used for 2 storey/G+1 building, we should use steel bar of 10mm dia for footing, combination of 12mm & 16mm dia of steel bar used for column, 12mm dia of steel bar used for beam and 10mm dia of steel bar used for rcc roof slab casting.

According to general thumb rule, we will assume a structure of G+2/3 storey/three floor residential building, using standard 9″ thick walls, the best mm bar used for 3 storey/G+2 building, we should use steel bar of 12mm dia for footing, combination of 12mm & 16mm dia of steel bar used for column, 12mm dia of steel bar used for beam and combination of 10mm & 12mm dia of steel bar used for rcc roof slab casting.

Best mm of footing for 1 storey (G+0)/2 storey (G+1)/3 storey (G+2) building:- Using thumb rule, the best mm of steel bar used in footing for 1 storey/(G+0) building, it could be 10mm dia of steel bar ([email protected]″C/C for mesh bar), for 2 storey/G+1 building, it could be 12mm dia of steel bar ([email protected]″C/C for mesh bar) and for 3 storey/G+2 building, it could be 16mm dia of steel bar ([email protected]″C/C for mesh bar).

Best mm of column for 1 storey (G+0)/2 storey (G+1)/3 storey (G+2) building:- Using thumb rule, the load bearing structure, the best mm of steel bar used in rcc column for 1 storey/(G+0) building, it could be 12mm dia of steel bar, for 2 storey/G+1 building, it could be combination of 12mm & 16mm dia of steel bar and for 3 storey/G+2 building, it could be 16mm dia of steel bar of Fe500 grade of steel and provided M20 grade of concrete with stirrups of [email protected]″C/C.

Best mm of beam for 1 storey (G+0)/2 storey (G+1)/3 storey (G+2) building:- Using thumb rule, the load bearing structure, the best mm of steel bar used in rcc beam for 1 storey/(G+0) building, it could be combination of 10mm & 12mm dia of steel bar, for 2 storey/G+1 building, it could be 12mm dia of steel bar and for 3 storey/G+2 building, it could be cobination of 12mm & 16mm dia of steel bar of Fe500 grade of steel and provided M20 grade of concrete with stirrups of [email protected]″C/C.

Best mm of rcc roof slab for 1 storey (G+0)/2 storey (G+1)/3 storey (G+2) building:- Using thumb rule, the load bearing structure, the best mm of steel bar used in rcc slab for 1 storey/(G+0) building, it could be combination of 8mm & 10mm dia of steel bar used, for 2 storey/G+1 building, it could be 10mm dia of steel bar used and for 3 storey/G+2 building, it could be cobination of 10mm & 12mm dia of steel bar of Fe500 grade of steel used and provided M20 grade of concrete.
