In order to make the seismic safety of RC frames depend not only on their strength but also on their ductility, the column-collapse is to be avoided. Because it is difficult to make columns ductile compared to girders and the ultimate capacity of frames is reduced owing to the "localized failure". Therefore, it is necessary to know the relation between relative strength of columns and their damage under intense earthquake motions. From these points of view, current report is intended to clarify the relative strength of columns necessary for designing weak-girder RC frames. It is also shown that the "equivalent 1-DOF modelling" is satisfactorily reliable in estimating earthquake response of weak-girder RC frames.
