How far apart should concrete columns be?
Generally, columns are spaced apart at 40 feet, 50 feet, or some other similar measurement. Architects and structural engineers habitually use these lengths in designing building configurations because steel mills generally produce structural members in these lengths.
How do you determine column spacing?
The distance between two reinforced columns ranges between 3-4 m for small buildings and 6-9 m for sizable facilities where large columns and free spaces are required. For ordinary structures, a distance of 5 m is appropriate, and the maximum span is 7.5, while the minimum is 2.5 m.
What is the standard size of pillar?
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”.
What size concrete do I need for a column?
First Of all, there is no standard size of columns. 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”.
What size columns for 2 storey (g+1) building?
Column size for 2 storey (G+1) building:-For this general thumb rule, we will assume a structure of G+1 (2 storey) residential building, using standard 5″ walls, size of an RCC column should be 9”x 12” (230mm x 300mm) with 6 bars of 12mm Fe500 Steel with m20 grade of concrete and stirrups of [email protected]″C/C.
What is the size of a column in M15 concrete?
If you use M15 concrete for one and half story structure the column size should not be less than 12”x9”. Try to maintain equal distance between the centers of two columns. Always plan a column layout on a grid. The distance between two columns of size 9”x9” should not be more than 4m centre to centre of column.
What is the size of RCC column in a concrete slab?
Column has not fixed size, it generally depends on different aspects such as loads acting on column, material used in column, grade of concrete, span between two column etc. According to these aspects the size of rcc column should be assumed or accepted as well as after that verification for safety is required.
