What is the load factor considered for steel structures when combination of dead load and earthquake load is considered?

A

1.5

B

1.3

C

1.2

D

1.7

Correct Answer: 1.7

In plastic design of steel structures, load factor is 1.7 when combination of dead load and earthquake load is considered i.e. 1.7(DL + EL) or 1.7(DL – EL).
