In this study, based on the shaking table test of two-stoned timber frame structure, we examined the validity of damage detection indices calculated by using response accelerations and strains, which were previously proposed for a unit frame. Applicability of the index f_i, based on the negative slopes of bending moment, became poor for the two-storied timber frame structure compared to the previous test of unit frame. While the index f_3, based on the discontinuity of strain energy, still can detect damage time and location of column accurately. Furthermore, a new index considering both f_2, using the negative slopes of shear force, and f_4, based on the discontinuity of kinetic energy, was proposed. The index accurately detects damage time when somewhere damaged in the whole structure.
