In the field of structural engineering typical problems include designing structures to be safe. Many innovative methods have been developed, tested and implemented to protect structures from earthquakes. Passive energy dissipation devices are one class of these protection strategies. The development of a hybrid passive control device (HPCD) including a high damping rubber sandwich damper in series with a bucklingrestrained brace (BRB) presents an innovative way to reduce structural response to dynamic loads. The criteria used to develop this device include energy dissipation for all levels of vibration, significant energy dissipation capacity for large events and an increasing stiffness with displacement. To adequately analyze this device, experimental characterization of highly damped natural and butyl rubber specimens was completed to generate the data necessary to correlate experiment and finite element analysis. The experimental data for the rubber was used to create the static and dynamic material properties in Abaqus. The hybrid device was analyzed using a sinusoidal displacement protocol at various maximum displacements. The hysteresis loops generated from the analysis demonstrate the behavior expected of the hybrid device. The hybrid device shows potential for reducing structural response under everything from wind to major seismic events.
