Resumen:

Performance-based earthquake engineering for RC buildings is necessary to link drift demands with the likelihood of onset of bar buckling. This damage state has been observed in RC buildings that responded to recent earthquakes. This research uses a database of reinforcing bars subjected to reversed cyclic axial loading, as well as a database of RC columns and walls tested by several authors under cyclic reversal lateral loading. In this database, the observed failure mode was related to bar buckling. A procedure is proposed for predicting drift capacity of RC elements considering buckling of longitudinal reinforcement. Results using this procedure are compared with experimental results. © Springer Nature Singapore Pte Ltd. 2019.
