Abstract
Modern societal needs call for a move towards reduced damage and continued (and often increased) operation instead of merely safety of life in the aftermath of large seismic events. The presented research introduces a few systems capable of meeting these needs. The use of these systems, in addition to reducing damage to the structure itself, should also reduce any damage to non-structural (and often much more valuable) components, thus preserving the operational capabilities post-earthquake. Experimental setup for a half scale, four (4)-storey structure tested at the Large High Performance Outdoor Shake Table (LHPOST) at UCSD is presented here. The tested structure utilizes some innovative components in addition to these damage reducing systems. Some key results from the test are presented here to showcase the capabilities of these systems. The future aim of this research is to provide guidelines for computer-aided modeling and simulation of such structures, helping in further research and greater industrial adoption of these components. To this aim, some models developed so far are also presented along with a comparison of the analytical and experimental results.
