This paper focuses on the experimental work related to the performance of isolated floor systems. Two types of isolated floor systems are considered: (i) a first proprietary system adopting special multi-directional spring units, and; (ii) an isolated system using concrete ball-in-cone isolation bearings with polyurethane balls as rolling balls. These systems were tested on 6-DOF shake table. The floor seismic excitation was obtained from nonlinear time history analysis of an SDOF frame designed as a structural fuse frame. The test results show that the isolated floor systems work well. The mechanical properties of these two isolated floor systems are also obtained in terms of acceleration-displacement relationship, which provides the foundation to better simulate these isolated floor systems in future parametric study of the combined solution.
