dc.description.abstractDue to the extreme damage seen in several recent earthquakes, several passive energy dissipation devices have been developed with different mechanisms of energy dissipation. Response spectra analysis across multiple earthquake suites is used to investigate the reductions in structural response and base shear forces to probabilistically assess the impact of these devices using suites of ground motions from the SAC project. Single-degree-of-freedom spectral analysis structures are used with nonlinear models of the sliding hinge joint (SHJ) and HF2V devices. Reduction factors are computed for each device compared to a linear, no-device structure. Force capacity for SHJ and HF2V devices are equivalent. Results are presented as 5th, 25th, median (50th), 75th and 95th percentile responses at each period (0.1-5.0s by 0.1s increments). Both devices show significant reductions in displacement at all spectral periods of 30- 60% (at median). Both increase base shear forces. However, SHJ systems show both a broader 5-95th percentile range, as well as larger increases in base shear due to their different velocity dependence in dissipating energy. The results provide initial design trade-off information in a probabilistic, performance-based framework for these devices.en
