3.why should we provide cranks in slabs

Question

Accepted Answer

Cranks are provided in slabs to resist the bending moments and shear forces.

Cranks help in distributing the load uniformly across the slab.
They increase the load-carrying capacity of the slab.
Cranks prevent the formation of cracks and improve the overall structural integrity.
They help in reducing the deflection of the slab.
Cranks are especially useful in areas where heavy loads or concentrated loads are expected, such as near columns or walls.
By providing cranks, the slab becomes more resistant to bending moments and shear forces.
Cranks also help in improving the durability of the slab by reducing the chances of cracking and failure.

Accepted Answer

Crank bar provide to live load nd dead road resistance the slab

Accepted Answer

To resist negative bending moment and shear force at the supports. It also resuces the brittle failure of slab-column.
