What is the standard distance between columns?

What is the standard distance between columns?

40 feet, 50 feet

How big should columns be?

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. You can never go wrong with strong columns.

How do you calculate column design?

Load Calculation of Beam

  1. 300 mm x 450 mm excluding slab thickness.
  2. Concrete Volume = 0.3 x 0.60 x 1 =0.138m³
  3. Concrete weight = 0.138 x 2400 = 333 kg.
  4. Steel weight (2%) in Concrete = = 0.138 x 0.02 x 7850 = 22 kg.
  5. Total Column weight= 333 + 22 = 355 kg/m = 3.5 KN/m.

What is column height?

Column – a vertical element of the building frame, designed for load perception from the overlapping elements and walling. Plant “Oberbeton” produces precast concrete columns of different lengths and cross sections. The minimum section size is 300×300 mm, maximum – 1200×1200 mm. The maximum height of a column is 24 m.

How do you design a beam?

Design of rectangular reinforced concrete beam procedure There are two approaches for the design of beams. Firstly, begin the design by selecting depth and width of the beam then compute reinforcement area. Secondly, assume reinforcement area, then calculate cross section sizes.

How do you calculate column weight?

Load Calculation on Column, Beam & Slab….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.

What is column weight?

Self weight of column is equal to weight of concrete in column and weight of Steel which is used in construction of column. First we calculate weight of concrete in column. A) weight of concrete used in column. Size of column = 230mm×230mm.

How much steel is in a column?

Ratio of Steel required to Cement Concrete

Different Parts of the Building Requirement of Steel TMT Bars in Kg
Ground Beams 230-330
Columns 200-450
Beams 150-300
Load Bearing Slabs 150

Which steel is best for slab?

TMT Steel or TMX steel is the best bet for house construction. They are the latest generation of reinforcement steel (high-strength and ductile than their predecessors) . They are graded as Fe415, Fe500, Fe500D, Fe550 i.e. yield strength of 415, 500 and 550 N/ sq mm respectively . Higher grade are also available.

Why steel is used?

Steel is used because it binds well to concrete, has a similar thermal expansion coefficient and is strong and relatively cost-effective. Reinforced concrete is also used to provide deep foundations and basements and is currently the world’s primary building material.

What is RCC made of?

The full name is concrete reinforced cement or RCC construction. RCC (Reinforced concrete) is concrete containing steel bars or rebars, called reinforcing bars. This formulation works very well since concrete is very compressive; simple to manufacture on-site, steel is very tension-intensive and inexpensive.

How much steel is required for 1m3 concrete in slab?

Minimum quantity of steel required for 1m3 concrete slab is 1%, now 1% of 1m3 = 0.01 m3, and we know that 1m3 steel weight is 7850 Kg, so weight of 0.01m3 steel = 0.01 × 7850 = 78.50 kg, so minimum quantity of steel required for 1m3 concrete slab is 78.50 Kg.
