Civil Engineering - Steel Structure Design - Discussion

350 is the correct answer.

Which is the correct answer 250 or 350?

Give me a proper explanation.

Sorry answer 250 is correct as,

It doesn't tell any condition that the member is actually a tensile member and it subjected to the reversal of stress.

If it is mentioned only we have to go for 350.

Otherwise, it is understood that it is "the member subjected to compressive loads resulting from wind or earth or seismic forces - 250".

350 for tension members.

250 for compression members.

350 is the right answer, because table 3 of is 800 2007 states that "A member normally acting as a tie or bracing not considered effective when subjected to possible reversal of stress into compression from action of wind or earthquake forces".
