Seismic Performance and Materials Quantities of Reinforced Concrete Frame Buildings Designed for Different Energy Dissipation Capacities. Rev.EIA.Esc.Ing.Antioq [online]. 2021, vol.18, n.35, pp.137-152.  Epub 31-Out-2021. ISSN 1794-1237.  https://doi.org/10.24050/reia.v18i35.1454.

The use of the Colombian seismic design and construction code requires the selection of an energy dissipation capacity (EDC) for the building that depends on the structural type and the seismic hazard at the site. This work investigates the effects on the materials quantities and the seismic behavior of reinforced concrete buildings due to the selection of an EDC superior to the minimum required for low and intermediate seismic regions. Twenty regular buildings with variations in bay lengths and height were designed according to the parameters and requirements for each EDC. Pushover analyses were performed to assess the potential seismic damage in a subset of those buildings. The results showed that the lowest amount of reinforcement in both seismic regions is obtained by selecting a moderate CDE, and that higher levels of seismic damage could occur when a CDE superior to the minimum is selected.
