Question

As per the limit design of steel structures, the IS 800 code on steel design stipulates the partial safety factor for resistance of member to buckling as
1. 1.10
2. 1.25
3. 1.50
4. 1.00
5. 0.80

Answer 1

Correct Answer - Option 1 : 1.10

Explanation:

As per IS 800:2007, Partial safety factor for materials:

Definition	Partial Safety Factor
Resistance, governed by yielding	1.10
Resistance of member to buckling	1.10
Resistance, governed by ultimate stress	1.25

 

Factor of safety for Resistance of connection:

Resistance of connection	Shop Fabrications	Field Fabrications
Bolts-Friction Type	1.25	1.25
Bolts-Bearing Type	1.25	1.25
Rivets	1.25	1.25
Welds	1.25	1.50
