Q1:

Factor of safety adopted by IS : 800 - 1984 while arriving at the permissible stress in axial compression, is :

A 2.00

B 1.00

C 1.67

D 1.50

ANS:C - 1.67

As per IS 800, the permissible stress in axial compression and tensions is 0.60fy.
FOS = yield stress/permissible stress.
FOS =fy/0.60fy = 1.67.
