Outline of Final Research Achievements

We studied the structural design method for newly-constructed reinforced concrete (RC) buildings that include the shear-failing RC columns with a large amounts of the longitudinal reinforcement and the transverse reinforcement. The collapse test of shear-failing RC columns considering axial-load redistribution and the earthquake response analysis of RC buildings which consist of the flexural columns and the shear-failing columns were conducted. The study reveals that the shear-failing RC columns contribute to the improvement of the structural performance of RC buildings.
