Knowing the (ultimate) energy dissipation capacity of structural members is a key aspect of seismic design based on the energy-balance, since it is the main parameter for verification. The gap in knowledge about the energy dissipation capacity of structural members is considerable, particularly for reinforced concrete (RC) structural elements. In this study, the energy dissipation capacity of three RC columns subjected to dynamic seismic loadings on a shake table is investigated. The columns are tested within a structure that represents a scaled portion of a three-story prototype building. Two of the columns reached failure and the third one was severely damaged. It is found that the total ultimate energy dissipation capacity of the two columns that failed is very similar, although they followed different loading paths and dissipated very different amounts of energy in the X and Y directions. Finally, it is shown that the chord rotation (at least alone) is not a good indicator of damage. |
