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.
