Abstract |
Recently, seismic resistant steel deformed bar has been developed and applied to practical applications. However, there is no provision that reflects the characteristics of seismic reinforcing bars on the design code, and the price is higher than that of ordinary reinforcing bars, and thus it cannot be universally used. In this study, seven full-scale specimens were subjected to cyclic loading tests, in order to accumulate evidence for the use of effective seismic reinforcing bars. The variables of the experiment are the magnitude of the gravity load acting on the wall and the material properties of the reinforcing bars used in this study. As a result, the seismic performance of the wall using seismic reinforcing bars was superior to that of the wall using ordinary reinforcing bars, and the difference in performance was remarkable when the gravity load acting on the wall was large. Also, it was advantageous to use seismic reinforcing bar with large diameter when the longitudinal reinforcement ratio is the same.
