Abstract
The effect of ground motion on a building is taken as energy input, and is absorbed as structural damage during strong earthquakes. The relation between yield strength distribution and damage distribution has already been determined experimentally by numerical analysis. The purpose of the present study is to contribute an analytical examination of the damage distribution law of the multi-mass shear system. By considering the resonance response of stiff-perfectly plastic multi-mass shear system, the author develops a theoretical damage distribution law, and shows that it is in accord with damage distribution laws previously proposed.
