Improvement and Evaluation for Seismic Resistant Capacity of Reinforced Concrete Frame and Braced System under Load Reversals

Recently, it is required to improve the structural performance, such as durability and earthquake resistant capacity due to the deterioration of structural components in the existing reinforced concrete building with the old aging and transition of design code. Therefore, the new technology should be developed, such as seismic retrofit and improvement of structural performance in the existing reinforced concrete building. This analytical study was performed to verify the effects of basic and reinforcing system in the reinforced concrete building. The analytical results by nonlinear finite element method were compared with the experimental results and the comparisons are judged to be good.
