Plan Columns Log For Free

Usually, columns are oriented in such a way that it falls in line with the masonry walls having no offsets in any direction. 3. The sectional length of the column should be in the major plane of bending. This helps to enhance the moment-resisting capacity of the column.

Construction of RCC columns involve following four steps: Column layouts. Column reinforcement work. Column formwork. Pouring of concrete.

Designing a reinforced column depends on the slenderness ratio, effective length, shape amount of external loads, eccentricity of loads, etc. These parameters are selected in such a way that it meets the suitable strength of the column and struts for which it is designed. Here a few parameters are discussed below.

Columns should be preferred to be positioned at the corners of the building and at the intersection of beams. They should be placed in such a way that the bending moments will be reduced in the beams. Avoid larger spans of beams. Avoid larger centre to centre distance between columns.

Basic key points taken in design Percentage of steel in RCC column is taken as 0.8% to 6% of the gross area. Minimum of 4 Bars are used in Rectangular column and 6 Bars in circular column. Transverse reinforcement (pitch not greater than)

Basic Rules in Column sizes Minimum column size should be taken as 9?X9? (230mmX230mm). Minimum Bar diameter is taken as 12mm. Grade of the concrete should be at least M20. Concrete cover is taken in between 25mm to 50mm values.

Between two columns should be between three to five meter are from 10 to 16.5. feet you can take the size of column minimum nine by nine inches.
