Performance Spectra-Based Methodology for the Implementation of Supplemental Dampers in Buildings Subjected to Earthquakes
An overview of the performance spectra method is first provided. Using this method, a 3-story, special moment-resisting frame is then retrofitted with four different types of supplemental dampers to meet two different performance targets. The results of the nonlinear time-history analyses show that the trial damping designs obtained by the method were close to the initial performance targets without any design iterations. The performance spectra can underestimate the reduction in base shear due to higher mode effects. However, this can be corrected using the supplemental damping properties computed from the method. This design example demonstrates the effectiveness of the performance spectra procedure for producing trial performance-based designs using different types of supplemental damping devices.
