Question
Consider the following statements regarding the slabs:
1. When the longer span to shorter span ratio is greater than or equal to two, it is a two-way slab.
2. In one-way slab, the load transfer is chiefly by bending in the shorter direction.
3. In two-way slabs, the load transferred by bending in both orthogonal directions.
Which of the above statements is/are correct?
A.
1 and 2 only
B.
3 only
C.
2 and 3 only
D.
1 and 3 only
Answer ( Option B)

3 only

Solution

• A slab supported on all edges with longer span to shorter span ratio less than or equal to two is called a two-way slab.
So statement '1' is incorrect
• In one-way slab, the load transfer is chiefly by bending in the shorter direction when the slab is supported on all the four edges.
However, the load transfer is by bending in the transverse direction of supports for two sides support one way slab. So, statement '2' is incorrect
• In two-way slabs, live load is transferred by bending in with longer and shorter direction. So statement '3' is correct.
