Abstract
In this study, based on the shaking table test of two-storied 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 f1, 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 f3, based on the discontinuity of strain energy, still can detect damage time and location of column accurately. Furthermore, a new index considering both f2, using the negative slopes of shear force, and f4, based on the discontinuity of kinetic energy, was proposed. The index accurately detects damage time when somewhere damaged in the whole structure.
