| Beam span | Beam type | Span/depth ratio |
|---|---|---|
| Up to 10m | Simply supported | 20 |
| Cantilever | 7 | |
| Continuous | 26 | |
| Greater than 10m | Simply supported | 20*10/span |
What is minimum size of column?
The minimum size of a column should not be less than 9”x9” for single story structure with M15 (1:2:4) concrete. If 9”x9” columns are to be used in one and half story building, always use M20 (1:1.5:3) concrete. If you use M15 concrete for one and half story structure the column size should not be less than 12”x9”.
What is the standard size of beam for 2 storey house?
Plinth beam size for 2 storey (G+1) house:- for 2 storey (G+1) house or in simple 2 floor building, general thumb rule, using standard 9″ thick walls, size of Plinth beam should be 9”x 12” (230mm x 300mm) provided with 2 nos of 12mm bar at top, 2 nos of 12mm bar at bottom and 1 extra bar of 10mm is provided in mid span
How do you calculate beam size?
Total depth of beam = effective depth + diameter of bar/2 + clear cover size. Total depth D= 225mm, It should be taken as 225mm. Width of beam = D/1.5, 225/1.5 = 150mm, so width of beam should be not less than 200mm in case of Block wall and 225mm in case of Brick wall.
What is the standard size of beam?
THE STANDARD SIZE OF THE BEAMS
In a residential building it is 9 ʺ × 12 ʺ or 225 mm × 300 mm standard size according to (IS codes). The minimum RCC beam size should not be less than 9 ʺ × 9 ʺ or 225mm × 225mm with the addition of a 125mm slab thickness.
What is thickness of beam?
There is a certain rules and guidelines, As per IS 456:2000, minimum depth/thickness of a RCC beam should not be less than 9″ (230mm), hence minimum depth/thickness of RCC beam is 9″ (230mm) thick, provided minimum size 9″×9, use of M20 grade of concrete with 2nos of T12 at bottom as tension bar and T10 at top.
What is the beam size for 4 storey building?
Beam size for 4 storey (G+3) building:- For this general thumb rule, we will assume a structure of G+3 (4 storey) residential building, using standard 9″ thick walls, size of an RCC beam should be 12”x 14” (300mm x 350mm) using 6 nos bar,4 bars of 12mm Fe500 Steel used at bottom and 2 nos of 12mm Fe 500 used at top
What is the size of RCC column?

What is the maximum height of column?
In general, Columns can be cast up to 1.2m to 1.3m height in single pour as per the standards. Greater heights of pours are also possible by using side windows at 1.2m height, through which concrete is to be placed to avoid segregation etc.
What is the maximum length of beam?
As long as you can use prestressed concrete beam there is no limit for beam length.
Can we use 8mm bar in beam?
As per IS 456:2000, in rcc slab, minimum diameter of main bar should not be less than 8mm (highly yield strength deform bar HYSD) or 10mm (plain bar) and distribution bar should not less than 8mm.
Can I use 10mm bar in beam?
10 mm dia bar can very well be used for the longitudinal reinforcemnt of a particular beam, but it all depends uopn the size and span of the beam, load over it . In short , while designing , designer calculates the required cross section area of steel required .

What is the span of a beam?
Span is the distance between two intermediate supports for a structure, e.g. a beam or a bridge. A span can be closed by a solid beam or by a rope.
What is beam in RCC?
What Is RCC Beam? Beam can be defined as a structural member which carries all vertical loads and resists it from bending. There are various types of materials used for beam such as steel, wood, aluminum etc. But the most common material is reinforced cement concrete (RCC).
