Civil Engineering - RCC Structures Design - Discussion

In case of load on simply supported slab the effective length will be considered from the one edge to another edge of the slab because the slab is not continuous (in simply supported slab the ends will be considered as free or pinned But not fixed or continuous). So the whole length of the slab will be affected by the load. So the effective length of the slab is equal to internal wall to wall distance + the length of the slab which is mounted on the wall on both sides.

B is the correct answer because as per clause 22.2 (a) is valid only for that S/S slab that is not built integrally with its supports.

Generally, S/S slabs are those slabs in which the beam is not cast monolithically with the slab. Hence B is the correct answer.

A is the correct answer because in case of same bearing width you can apply this but it does not satisfy in case of different bearing width which was not mentioned in question can anyone discuss this?

Clear span + effective depth of the slab.

Clear Span + Width of the support (wall or column)
whichever is less.
Or
Clear Span + 2 * Half Width of the support (wall or column).

It should be option C.

We adopt the lesser value of the following as effective span.
1. Clear span + Effective depth.
2. Clear span + 2 (0.5 * thickness of wall).

Answer is none of the above as to find out the effective span two calculations are required and smaller value will be treated as effective span.

It should be either,

A) Clear span + effective depth of the slab.

B) Or Clear Span + Width of the support (wall or column) whichever is less.

Clear distance between the inner faces of the walls plus HALF the thickness of the wall.

Clear span plus effective depth of the slab.

I am confused and I search with google.

1. Clear span + efficient depth of the slab.

2. Clear span + 2 * (half of width of column).

The Effective span of the simply supported beam or slab is Min (clear span + eff depth, clear span + width of support).
