Design of Steel Structure
The elastic strain for steel is about

1/2 of strain at the initiation of strain hardening and about 1/12 of maximum strain
1/12 of strain at the initiation of strain hardening and about 1/120 of maximum strain
1/12 of strain at the initiation of strain hardening and 1/200 of maximum strain
1/24 of strain at the initiation of strain hardening and about 1/200 of maximum strain
