When two or more loads are acting on a structure in addition to dead load, then ASCE permits the loads other than dead loads to be multiplied by a factor of 0.75 is:-

A

Compulsory

B

Compulsory in some case

C

Depends upon the engineer

D

Depends upon loads

Correct Answer: Depends upon the engineer

Factor of 0.75 is only helping in listing the minimum conditions to be considered.

A

0.60

B

0.65

C

0.70

D

0.75

Assertion A: The load factor for live load is greater than that for dead load.

B

Both A and R are true but R is not the correct explanation of A

C

A is true but R is false

D

A is false but R is true
