In analysis, he fac ors such as cons ruc ion sequence, creep and shr inkage of concre e, difference of press s ress of ver ical members, adjus of componen s on he process of cons ruc ion and e c are considered. The resul s of analysis indica ed ha composi e columns occur he maximum ver ical deforma ion of abou 80mm, reinfor ced concre e core shear wall occur he max imum ver ical deforma ion of abou 70mm a middle posi ion of he s ruc ural heigh when half a year af er he s ruc ure roof is cons ruc ed. The max imum ver ical deforma ion difference be ween composi e columns and shear walls achieves 12mm approx ima ely. I is poin ed ou ha arranging cons ruc ion sequence in reason will occur minor in ernal force in ou riggers coming from ver ical deforma ion difference beween composi e columns and shear walls.
