In this article, we will experience the basic thumb rules to be followed for giving a column design. Obviously, columns must be planned in agreement to the complete powers following up on the structure, however separated from that, it is fundamental for each Civil specialist and Architect to recall a couple of thumb rules so they are kept from committing errors.
The three base guidelines to be followed are as per the following:
Let us look at these options, in detail, now.
The size of the columns relies upon the absolute burden on the columns. There are pivotal burdens and horizontal burdens. Enormous beam ranges incite bowing second in the beams, yet additionally in columns which are pulled by the worries in the beams. It is critical to utilize progressed basic structure programming like ETabs or Staad ace. I energetically suggest each basic originator gain proficiency with these products. The thumb rules are for general structuring in exceptionally little undertakings.
For this overall thumb rule, we will expect a structure of G+1 floor high, utilizing standard 6" dividers. Least size of a RCC column ought not be under 9" x 12" (225mm x 300mm) with 4 bars of 12 MM Fe415 Steel.
Nowadays the base we use in our undertakings is 9" x 12" (225 mm x 300mm) with 6 bars of 12 MM Fe500 steel. You can never turn out badly with solid columns. I likewise suggest utilization of M20 grade concrete for the structure (proportion 1 section Cement: 1.5 parts Sand: 3 sections Aggregate with 0.5 parts water by volume). I suggest utilization of 8 MM stirrups a way off of 150 MM place to focus all through the length of column.
This arrangement of 9" x 12" RCC columns is alright for G+1 Floors. There is a great deal of different contemplations, however this is only a thumb rule.
For the above column arrangement, a range of up to 5 meters is very sheltered. One can utilize beams of size 9" X 12" (225 MM x 300MM) with a chunk thickness of 5" (125 MM) cast in M20 concrete for ranges up to 5m. There are different contemplations like auxiliary and tertiary ranges, point loads and divider loads which must be thought of. It is convoluted, yet thumb rules can work if the structure is straightforward. It is constantly prescribed to utilize basic plan programming like ETabs or Staad master for structure.
In a beam of up to 5 meters length, optional ranges of up to 4 meters, divider heaps of up to 8 kN per running meter, I can utilize steel as beneath.
This setup can change contingent upon a great deal of elements.
Setting of columns rely totally upon the arrangement. An organizer has a significant activity. A network column arrangement is constantly favored so as to lessen point loads and superfluous inconveniences while development. This diminishes the expense of development just as time required for development. Beams which have congruity with other just upheld beams have diminished twisting minutes, and in this manner require less steel and solid profundity to be sheltered.
Columns must be associated with one another for smooth exchange of burdens. An accomplished organizer will remember such things when arranging the structure.
