Abstract:
Theoretical moment-curvature analyses were performed in this study for analyzing the effects of cyclic behavior of reinforcing steel on seismic performance of reinforced concrete members. Cyclic stress-strain relations for reinforcing steel were estimated from an analytical model proposed in the literature and considering the onset of buckling of a steel rebar defined according to an approach proposed in this study. The ACI318-95 provisions for evaluating probable flexural strength are used for relating interstory drift and strain demands in longitudinal reinforcement of typical sections of reinforced concrete members subjected to earthquake loading.
