How do you calculate beam and column size?

2. Beam Load Calculation:

  1. 230 mm x 450 mm excluding slab.
  2. Volume of Concrete = 0.23 x 0.60 x 1 =0.138m³
  3. Weight of Concrete = 0.138 x 2400 = 333 kg.
  4. Weight of Steel (2%) in Concrete = = 0.138 x 0.02 x 8000 = 22 kg.
  5. Total Weight of Column = 333 + 22 = 355 kg/m = 3.5 KN/m.

How do you set a column in a building?

1.1 Positioning and orientation of columns

  1. Columns should preferably be located at (or) near the corners of a building, and at the intersection of beams/walls.
  2. Select the position of columns so as to reduce bending moments in beams.
  3. Avoid larger spans of beams.
  4. Avoid larger centre-to-centre distance between columns.

What are the 3 types of columns?

(Ionic, First, The) three types of columns are Doric, (Ionic, slender, they), and Corinthian.

What is the maximum distance between columns?

The maximum span between columns for normal structures is 7.5 m and minimum spacing is 2.5 m.

What is the standard size of beam?


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.

How do I design the size of a column?

For this general thumb rule, we will assume a structure of G+1 floors high, using standard 6″ walls. Minimum size of an RCC column should not be less than 9” x 12” (225mm x 300mm) with 4 bars of 12 MM Fe415 Steel. These days the minimum I use in my projects is 9″ x 12″ (225 mm x 300mm) with 6 bars of 12 MM Fe500 steel.

How do you calculate beam size?


  1. Fig: Calculation of minimum size of R.C.C beam size as per IS 456: 2000. Effective depth =Span/Basic value. Total Depth = Effective depth + dia./2 + Clear Cover. …
  2. Fig: Simply supported beam. Where, Le = Effective length. …
  3. Fig: Cantilever Beam. Span of cantilever beam = 2 m. …

What is a beam in structure?

A beam is a structural element that primarily resists loads applied laterally to the beam’s axis. Its mode of deflection is primarily by bending. … Beams are characterized by their manner of support, profile (shape of cross-section), equilibrium conditions, length, and their material.

What is the minimum spacing of stirrups?

Minimum spacing between two bars can be taken as approximately 50–75 mm. According to cl. 26.5. 1.5 of IS 456, the maximum spacing of the stirrups = 0.75 d = 0.75 (450) = 337.5 mm = 300 mm (say).

How do you calculate beam depth?

according to as per IS code 456 minimum depth of simply supported beam is about L/20 and minimum width of beam is about depth/1.5. according to ACI (American concrete Institute )code 318—14 minimum depth of beam is depend on length of beam if length of beam is about 20 feet then minimum depth of beam should be 20 inch.

Is 456 a column design?

The maximum design stress of steel is 0.87 fy. Sections 10.21. 4 and 12 of Lesson 21 explain that all columns including the short axially loaded columns shall be designed with a minimum eccentricity (cls. 25.4 and 39.2 of IS 456).
