This paper describes the equivalent linearization method considering strength reduction of brittle elements. The following facts are found by numerical investigation employed time-domain response analyses. The maximum response of the weak story where strength of brittle element is lost is well approximated by the model whose brittle element in weak story is removed in advance. While the maximum responses of the stories where strength of brittle elements are not lost, arise typically before strength of brittle element of weak story has been lost. In the evaluation by equivalent linearization method, both responses, which correspond above-mentioned two states, are evaluated, and greater responses of two states are adopted as final results. Numerical validations are conducted not only for single-story collapse model but also multi-story collapse model. The results of proposed method well agree with time-domain analyses in both cases.
