Question

For roofs of slope greater than 10˚, the imposed load is reduced by ____ for every degree rise in slope.

(a) 0.02 kN/m^2

(b) 0.05 kN/m^2

(c) 0.75 kN/m^2

(d) 0.5 kN/m^2

I had been asked this question by my college director while I was bunking the class.

This intriguing question originated from Characteristic Loads in chapter Structural Analysis, Loading and Load Combinations of Design of Steel Structures

Answer 1

Correct option is (a) 0.02 kN/m^2

To explain: As per IS 875, for roofs of slope greater than 10^o, the imposed load is taken as 0.75 kN/m^2 and reduced by 0.02 kN/m^2  for every degree rise in slope.
