| Outline of Final Research Achievements |
We researched a seismic structural design methodology and technique on reinforced concrete structure buildings, which would suppress damages and residual leaning deformation in them. Beam, in which was arranged high strength deformed steel bars at top reinforcement, performed well hysteresis loop such as vibration control structure building with secondary stiffness of the structure just after yielding of hysteresis damping device. Column, in which is designed to be with relevant righting moment due to axial force, also was found to performed well re-centering.
Moreover, reinforced concrete buildings composed of these beams and columns, was also revealed to perform well re-centering even if several big earthquakes attack them, by time history response analysis.
