"effectively restrained in direction but not held in position at the other end".
According to Table 11 [IS 800:2007]- Eff. Length= 2.0 L.

@All.

I will explain this in easy way;

Held in position= it can't move.
+
Restrained in direction = can't rotate
= fixed one end.

Effectively Restrained in direction = can't rotate.
+
Not held in position = it can move.
= roller.

Therefore support conditions are one end fixed and another one roller.
Theoretical value is 1 and the recommended value is 1.2.

The correct answer is 1.2L.

Suman said:   6 years ago
Ans should be 1.2L as one end is fixed and other end is allowed to move in horizontal direction only so as per IS 800:1984 Clause 5.2.2 the ans should be 1.2L.

1.2L is the correct answer.
