- Abstract
- The seismic resistance achieved by optimizing the design of the conventional members of a structure equipped with structural control is evaluated. Viscoelastic (VE) dampers and active bracing system (ABS) are studied individually, as well as combined as a hybrid system for their effectiveness in reducing the response of seismic structures. Two convex models are used to estimate the maximum response of structural systems subjected to uncertain seismic excitations. A reduction factor is used to calibrate the convex models for a specific excitation. An average reduction factor is also defined by averaging a set of excitation-specific reduction factors. The average reduction factor can be used for unknown excitations with an assumed energy bound and certain common earthquake characteristics.
