Abstract

A new low-damage seismic system, the Inertial Force-Limiting Floor Anchorage System (IFAS), has been developed. The IFAS attempts to reduce building response in earthquakes by providing a deformable connection to the floor diaphragm. The IFAS development included: (1) creation and full-scale testing of IFAS prototypes; (2) an analytical parameter study to develop a design space for the IFAS; (3) a shake table test to demonstrate the IFAS concept. This paper presents a summary of selected research performed to develop the IFAS including: (1) key findings from the analytical parameter study that produced a feasible design range for the IFAS; (2) key results from the shake table testing; and (3) results from analyses of a calibrated model to clarify and augment the results of the shake table test. These results show the potential for the IFAS to be effective in reducing building response in an earthquake, including inter-story drifts and floor accelerations.
