This paper presents a study on the effects on damage concentration in RC buildings by the cumulative strength index (C_<TU>) distribution along the stories. Dynamic response analyses were conducted for two types of building: the one type has a weak story; the other type has two weak stories. The following conclusions were derived from the dynamic response results: 1) In case of the building with the same C_<TU> in all stories, the damage can concentrate in all stories, although the damage is like to concentrate in the first story; 2) In case of the building with weak first story, if C_<TU> of the first story is 20% to 30% weaker than the averages of C_<TU> in the building, the damage concentrates in the first story; 3) In case of the building with two weak stories, damage will concentrate in which weak story depends on the margin of C_<TU> of between the weak stories. However, beam yielding mechanism should be considered, especially in case of the building with unbalanced C_<TU> distribution along the stories or that C_<TU> is large.
