| Research Abstract |
An evaluation method of seismic performance for reinforced concrete frame structure including brittle members was developed. The developed method is applicable to seismic performance evaluation uniformly for new, existing and damaged buildings with higher accuracy. Repairability evaluation based on damage to structural members and structural safety based on residual seismic capacity are focused on in this study. Major items investigated are (1) development of analytical model for deterioration shear capacity of brittle members, (2) analysis on behavior of frames including members with brittle failure mode, (3) evaluation of damage in structural members and residual seismic capacity of frames, (4) proposal on estimation of safety limit state, and (5) proposal on estimation of repairability limit state.
