Rectangular Columns: Minimum Size: Typically, the minimum size for a rectangular column might be around 12 inches by 12 inches. Standard Size: Standard sizes can range from 16 inches by 16 inches to 24 inches by 36 inches or larger, depending on the specific structural needs. 2. The column size for a 20 feet span would depend on several factors, including the load-bearing capacity of the material and the design specifications. For an estimation, a reinforced concrete column for a 20 feet span might typically have dimensions of approximately 12 inches by 12 inches (12"x12").

I was reading ACI 314R-11, It is specified that the minimum column dimension is 250 mm or the vertical distance between lateral supports over (10 ,9 or 8, depend on location). When I rechecked ACI 318 I didn't notice any note regarding this issue. Note that for a 2 story building with 3m ceiling height a column with width 30 cm minimum can be a. The minimum size of a column should not be less than 9"x9" for single-story structure with M15 (1:2:4) concrete. If 9"x9" columns are to be used in one and half story building, always use M20 (1:1.5:3) concrete. If you use M15 concrete for one and half story structure the column size should not be less than 12"x9". Distance Between 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. You can never go wrong with strong columns. 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. If possible use square columns only. At least take 4 no's of bars in column. The top and bottom area of the column should be same.

According to ACI 318-19, section 10.7.3, the minimum number of bars for concrete columns are as follows: Four within rectangular or circular ties. Six enclosed by spirals or for columns of special moment frames held by circular hoops. Three within triangular ties Note: Definition and Usage The column-width property specifies the column width. The number of columns will be the minimum number of columns needed to show all the content across the element. column-width is a flexible property. Think of column-width as a minimum width suggestion for the browser. The minimum column size as per code provision is taken as 9"X9" for building structure, depending upon the loading condition and building specification the column size may varies. If the loading on the structure is higher than we have give suitable dimensions of column which is greater than minimum sizes (9"X9"). In waffle slab construction, minimum column size is dependent on the overall thickness of the slab. The right-hand scale on the chart above provides minimum square column sizes for various slab thicknesses. For light loads, reduce the indicated column size by 2 to 4 in. (50 to 100 mm). For heavy loads, increase the indicated column size by 4 to.

For the 10 storey building the size of column will be 700 x 700 mm. while for the 20 storey building the size of column for the first seven (1 to 7) storey the dimension of column will be 750 x 750 mm and after seven to fourteen (8 to 14) for 20 storey building the size of column will be 600 x 600 mm while for 15 to 20 storey the dimension of co.
a) Least lateral dimension of the column. b) 16 times the diameter of the smallest longitudinal bar nearest to the compression face of the member. c) 48 times the diameter of the tie. Pitch of the helical reinforcement should not be more than least of the following: a) 1/6th the diameter of the concrete core. b) 75mm. Minimum size of RCC column: -The minimum size of an RCC column should not be less than 9"x 9" (230 x 230 mm) with 4 bars of 12mm Fe500 Steel with M20 grade of concrete and T8 @ 6″C/C stirrups.
