THE STANDARD SIZE OF THE BEAMS

In a residential building it is 9 ʺ × 12 ʺ or 225 mm × 300 mm standard size according to (IS codes). The minimum RCC beam size should not be less than 9 ʺ × 9 ʺ or 225mm × 225mm with the addition of a 125mm slab thickness.

THE STANDARD SIZE OF THE COLUMN

The size of the columns depends on the total load on the columns. The minimum column size should not be less than 9 "x9". 9 ”x9” columns are to be used for a single-story concrete grade M15 (1: 2: 4) structure (cement: sand: aggregate).

THE MINIMUM THICKNESS FOR A CONCRETE SLAB

Concrete is generally applied with a thickness of 2 inches or more, but the thicker it is, the stronger the slab will be. Four (150mm) inches is more common for a slab
