Lease size of the column should not be lower than 9 x 9. Thumb rules for RCC Structures. Design Rules of Thumb In the early stages of a project we are often asked how large structural elements will be before we have had a chance to perform the nec-essary computations.

The topic is related to the RCC column especially for those civil engineering students who are working on construction sites and especially for non-civil engineering people because they dont know how to design the RCC column about reinforcement detail and also it is concrete technology etc. The size of the columns is based on the complete load on the columns. The distance between two columns of size 9x9 should not be more than 4m centre to centre of column.

Increase in the distance between two columns This increases the dimensions of the columns as well the depth of the beam 2. Thumb rules for making a Column Layout. For this general thumb rule we will assume a structure of G1 floors high using standard 6 walls.

For accurate estimation you can refer to Bar Bending Schedule. For this overall thumb rule we will expect a structure of G1 floor high utilizing standard 6 dividers. Roof slab 80 kg per cubic metres.

Thumb rule no2 Distance between the columns Try to maintain equal distance between the centres of two columns. According to column design and Thumb Rule minimum column size for 10m span is 600mm600mm 2424 for 4 storeyfour floor G3 residential building using M25 grade of concrete ratio 112 with Fe550 grade of steel when axial load 4950kN is applied on each column. Design of RCC Column as per IS 456.

Size of the columns. The size of the columns is influenced by the total load on the columns. Column 160180 kg per cubic metres.

Height of the building Increase in the number of floors is directly proportional to the dimensions of the columns. Thumb rule to estimate Steel quantity of above slab Volume of Concrete x Density of Steel x of Steel of Member. Guide and Basic Rules for reinforced concrete column design.

Alignment of Columns A rectangular grid is to be made for placing the columns. 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.

Size of the Columns 2. According to column design and Thumb Rule minimum column size for 7m span is 230mm300mm 912 for 1 storeysingle floorground floor G0 residential building using M20 grade of concrete ratio 1153 with Fe500 grade of steel when axial load 606kN is applied on each column. A 16th the diameter of the concrete core.

Considerations should be given on the following thumb rules. The least spacing of the lateral ties may be 150 mm and for spirals the minimum pitch shall be 25 mm or three times the diameter of the helical bars whichever is greater. However architectural considerations may prevent the use of deep concrete beams and the designer would be obliged to select wide beams.

Basic rules for the design of RCC column by thumb rules its also. The Minimum number of steel bars in the rectangular column should be 4 and for the circular column should be 6. This is the thumb rule to design a column to bear.

Given below the details of basic structural elements of a RCC building. Always plan a column layout on a grid. I generally use a minimum of 4 bars with 2 bars of 12 MM thickness in the bottom of the beam and 2 bars of 10 MM at the top of the beam.

Column size for 7m span for 2 storeytwo floorG1. Designing structural Components has to be done in a systematic and calculated way. If M-15 grade of concrete material is used the dimension of the column should be 9 x 12.

Least size of the column should not be lower than 9x9. Remember a single simple formula for quantity of steel reinforcement in RCC building as 80120160 1. This helps in avoiding mistakes and.

First Thumb rule - Size of the columns. Top 10 Quick guides for Reinforced concrete Column design. The Minimum number of steel bars in the rectangular column should be 4 and for the circular column should be 6.

We have found the follow-ing rules of thumb to be useful in estimating the approximate depth of a structural member as well. Beam 120 kg per cubic metres.
