Shake‐table test performance of an inertial force‐limiting floor anchorage

IIn 2011, the PIs Robert B. Fleischman, Richard Sause, and José I. Restrepo, recruited researchers to work on their vision outlined in the project entitled NEESR: Inertial Force-Limiting Floor Anchorage Systems for Seismic Resistant Building Structures funded by the National Science Foundation (Award No. CMMI-1135033) and the George E. Brown, Jr. Network for Earthquake Engineering Simulation Research (NEESR) program (Award No. CMS-0402490).

A major part of this project was the shake-table test that was conducted at NHERI@UCSD with goal to assess the performance of the inertial force-limiting floor anchorage system. The test was lead by Prof. José I. Restrepo and Prof. Robert B. Fleischman.

Georgios Tsampras as a graduate student at Lehigh University and Prof. Richard Sause contributed to this shake-table test with the development, design, assembly, installation, and monitoring of four friction devices used as the limiting-force hysteretic components along the main direction of the earthquake motion. In addition, they contributed to the construction of the specimen, the post-earthquake inspection of the specimen, and the interpretation of the collected data.
