9. CONCLUSIONThe new AIJ Guidelines is outlined, which provides deterministic and probabilisticmethods of evaluating the actual seismic performance level of a designed reinforcedconcrete building. The limit states of the structures are defined based on the residualdamage rates of members corresponding to the performance objectives as: (1)serviceability, (2) minor repair, (3) major repair, and (4) safety. The deterministicprocedure evaluates the basic seismic capacity index for each limit state, which isdefined as the amplitude ratio of the capacity earthquake to the standard earthquake,where the capacity earthquake is to induce the response equal to the limit state. Theprobabilistic evaluation method is provided as an additional procedure, where theperformance level is expressed using the probability of exceeding the limit state bysite-specific earthquakes during design service life.The Guidelines is being translated into English and the English version is to bepublished from AIJ in the near future. We hope the Guidelines will be referred widelyas research and technical documents as well as model code of practice for seismicperformance evaluation. It is expected that more sophisticated alternative methodswill be proposed based on reliable verification through intensive research in the future.ACKNOWLEDGEMENTThe Guidelines was drafted by members of the Subcommittee on performanceevaluation and limit states, the Steering committee on reinforced concrete structures,the Architectural Institute of Japan, including drafting WG members: ToshimiKabeyasawa, Toshikatsu Ichinose, Daisuke Kato, Hitoshi Tanaka, Yuuki Sakai,Hiroshi Kuramoto, Hideyuki Kinugasa, Taizo Matsumori, Nobuyuki Izumi, KazuhiroKitayama, Masaki Meda, Kazuaki Tsuda, Masaru Teraoka, and Hajime Okano.
