Abstract

The study analyzes the behavior of reinforced concrete buildings with moment-resisting frames equipped with dampers, using potential energy to numerically monitor the onset of collapse. IDA curves were employed to obtain the collapse margin ratio (CMR) as the primary indicator of seismic performance, following the FEMA P695 approach. Buildings with 3, 6, and 9 stories were evaluated, incorporating different levels of supplemental damping (5%, 10%, 20%, 30%, and 40%) and both linear and nonlinear dampers (1.0, 0.7, 0.5, and 0.3). The research followed a quantitative, quasi-experimental approach. Results showed that the CMR increased between 1.08 and 2.46 times in buildings with dampers compared to those without them. Additionally, higher damping increased the CMR, although nonlinear dampers did not achieve the same effect. A correlation between the CMR and the indicators was identified, allowing for the prediction of seismic performance.
