How do I extend my RCC?

How do I extend my RCC?

1. Before expanding an existing RCC slab first you have to check the reinforcement ratio used in the slab, because a slab is designed on basically two parameters,
2. Now for extending, design the slab and try to make a good bond between existing and new slab.

Is it possible to add a column for an existing RCC structure?

Yes, it can be added. If you have the right money then everything is possible. However, the only type of column that I can think of, to provide after the construction of an RCC structure is a cantilever column.

What is the maximum span between columns?

The maximum spacing among two columns is 7.5 meter or 24 feet. (Since 1 meter is similar to 3.28084 feet). The minimum spacing among two columns is 2 to 3 meter or 5 to 7 feet.

How far can concrete columns span?

What is the maximum and minimum distance between reinforced concrete columns? The maximum span between columns for normal structures is 7.5 m and minimum spacing is 2.5 m.

What is the minimum size of reinforcement bars in RCC columns?

The minimum size of rcc column is 9″ x 9″, contain steel reinforcement of 4 bars of 12mm with stirrups of 8mm steel rings at a distance of 150mm centre to centre.

How many floors we can construct without pillars?

Yeah you can build structure up to 3 floors without columns. The provision of columns depends on the type of structure you are going to build, for a grey structure there is no need of provision columns and beams, in this type of structures the function of beams and columns are carried by load bearing walls.

How do you do column spacing?

On the Page Layout or Layout tab, click Columns. At the bottom of the list, choose More Columns. In the Columns dialog box, adjust the settings under Width and spacing to choose your column width and the spacing between columns. If you want columns of varying widths, deselect the checkbox next to Equal column width.

How far can a beam span without support?

A 2×10 beam – made up of two 2x10s nailed together – can span up to 11′ without support beneath a deck that is 4′ wide. For a more normal-sized deck, the same beam can span 8′, supporting a deck that is 8′ wide.

How do you place a column in a floor plan?

Always plan a column layout on a grid. Maintain equal distance between the centres of two columns. If using the minimum size of column 8” x 8” (200mm x 200mm) distance should not more than 3.5 m centre to centre of column distance.

How to finish the reinforced concrete columns in a building?

The reinforced concrete columns in a building can be finished using plaster render, cladding’s or left with the concrete color. Whatever the finish, it should give good aesthetics to the wall facades. These columns may be erected free-standing or within the building fabric.

What is the permissible load for columns with helical reinforcement?

The permissible load for columns with helical reinforcement shall be 1.05 times the permissible load for similar member with lateral ties or rings. This provision can be made applicable only if the ratio of volume of helical reinforcement to the volume of core is not less than

What is the minimum diameter of longitudinal reinforcement in column?

(iii) A column having helical binders must have at least six bars of longitudinal reinforcement within the helical reinforcement. (iv) The minimum diameter of the longitudinal bars shall not be less than 12 mm and the maximum diameter should preferably not exceed 50 mm.

What is the difference between a long column and a short column?

On account of its buckling tendency a long column has less strength than a short column of the same sectional area and hence can carry lesser loads as compared to short column.
