Abstract: In high seismic hazard zones, the structures are expected to enter the inelastic range, ensuring that adequate energy dissipation can be achieved. For this, it is recommended, among other aspects, to define a beam-to-column stiffness ratio for framed structures that allows achieving the strong column-weak beam criteria. This parameter is analyzed based on the building’s height when the dynamic soil-structure interaction (DSSI) is included on the model. The aforementioned elements could significantly change the collapse mechanism and performance building as well. This research analyzes how DSSI influences the collapse mechanism and performance level of eight-story structure with dual frame-wall RC systems, located in Santiago de Cuba municipality. The dynamic soil-structure interaction was taken into consideration for the analysis models, through A.E. Sargsian formulas. For this, the nonlinear static analysis (Pushover) with ETABS v18 software was used. Structures resting on soil type D were studied, as defined by Cuban standard NC 46:2017. It was concluded that the use of DSSI has a significant influence on the collapse mechanism and level of building performance.
