Analisis Pengaruh Kinerja Struktur Damping Rasio Tuned Mass Damper Dan Viskositas Damping

---

Sructural analysis uses Tuned Mass Damper (TMD) and viscosity damping to reduce excessive vibrations from dynamic loads which can cause failure in building structures. To reduce damage to buildings, it is necessary to select the right ratio damping system. Many structural systems use damping ratios, including TMD and damping viscosity. The addition of the damping ratio affects different building masses and changes in the parameters of the damping ratio. This research aims to determine an effective damping ratio system with variations in building mass, as well as determining the damping ratio parameters and specifications between TMD and damping viscosity. ETABS software is used to design building structures with damping ratios, and the time history analysis method with Chichi earthquake loads is applied to 3D modeling. The research started from a literature review and then created structural modeling and used the system's equations of motion. The results of this research show that the structural performance of buildings shows that the natural period of buildings has decreased. Damping viscosity reduces an average of
26.54% and TMD by 12.34% compared to structures without damping ratio. Base shear with TMD decreased an average of 11.27% in the x direction and 37.36% in the y direction, while damping viscosity decreased an average of 76.77% in the x direction and 70.66% in the y direction. Story displacement with TMD decreased on average by 42.31% in the x direction and 29.07% in the y direction, while damping viscosity decreased on average by 5.68% in the x direction and 18.94% in the y direction. In conclusion, the greater the damping ratio percentage of TMD can reduce the movement between building floors. Damping viscosity needs to pay attention to the force generated, because this force can dampen earthquakes optimally but can increase displacement if it exceeds the optimal value.
