Load sequence in phases can be considered applying the self-weight load only to the story added in the appropriate phase.

Assuming that the material will not go into yield stage ( will always be at the elastic stage), is there any need to consider load sequence in construction stage for structural analysis?

I think there is no need, because no matter what, the final finished structure should always have the maximum loads at each floor/element, whereas during the construction, each floor/element loading is only partial. So if we consider the final structure analysis, we already consider everything adequate for design. No?

But why code of practice still recommend it?
