I agree with you on that; i myself encounter this on all my calculations. Everyone with a sane mind will design anything just to stay on the "safe" side.
But (un)fortunately we are talking about the modern code requirements here which guide us to design not only safe but also economic strctures.. All these scientific papers and books are working with simple, regular, 2D structures; but 90% of the time we don't have a clear code "prescribed" situation. We are then left with our engineering intuition to decide what to do; and that's the fun part of this profession.
Where i'm going with this is that this particular problem(topic) should be a little more detailed and more clear(perhaps someone with more exp here will make it clear for us plz). I do NOT want to rely on the "pure" statement that proper detailing will take care of plastic hinges. Maybe it's just me, but i like to see numbers that will prove me i'm right.
Another thing here, that was mentioned in this topic and concerns the primary and secondary members in seismic analysis and design:
How do we treat the secondary members during analysis? Do we neglect their stiffness during EQ and account them only for their mass and for gravity load transfer?
And, if so, how do we know when to do this? Is this the paragraph that talks about dual, frame, wall etc. systems?
Regards
