The energy based seismic design for R/C structure have been developed by authors and others. The design method is to predict the maximum value of response displacement and compare the damage with the allowable maximum displacement. Up to the present, the predicting method on maximum response displacement is proposed and the validity is analytically confirmed. In order to establish the performance based seismic design, however, the following investigations should be still necessary. (1) The evaluation of damage at the each limit state(serviceability, reparability, safety) of R/C member subject to earthquake (2) The energy dissipation capacity of R/C member with flexural yielding In this paper, the static loading tests are conducted focusing on the loading history and two specimens are statically tested by using response excursion under each earthquake, other specimens are tested by regular reversed cyclic loading. The experimental results showed that each limit state is clarified and the energy dissipation capacity of specimen tested by using response excursion under each earthquake is closely related to the one obtained by regular cyclic loading. The required data to propose the calculation method of the energy dissipation capacity of R/C beam with flexural yielding subject to earthquake is obtained.
