Because the place where bm and shear force is minimum there will be less displacement to the structure which meets with the point that we can easily provide construction joint in that place.

SF means shear force.

Mukesh said:   6 years ago
What is SF?

Yes, you are Correct @Rakshith.

Construction joints are provided at the position where the bending moment is minimum. Usually provided at 1/3 from the support in site.

Rakshith said:   8 years ago
Construction joints are provided where the bending moment is Zero and also to have a continuity of work in the next day.

What is construction joint?

I think Construction joints are not provided they are formed, as the construction of the whole structure can't be done in a single stretch (the place where fresh Concreting is done on the previously casted member forms a construction joint).

How is it so that at 18 m apart in huge structures? Is it not a very big space?

Shishpal said:   9 years ago
How can say that construction joints are provided where B.M &S.F are small?

Because both are inversely proportional to each other.
