The new seismic-free system (SFS21) is developed under the concept of longevity and earthquake-proof design of buildings. This system consists of two parts. One is the RC core-shaft on top of which a seismic-free mechanism composed of double-layered rubber bearings is installed. The other is the office or residential space hanging from the hat-truss. In this paper, we describe the main concept of SFS21 and the results of analytical studies, static loading tests and shaking table tests. The shaking table tests use a 3-dimentional 1/16-scale model which employs double-layered rubber bearings and concrete weight. Both of the static loading tests and the shaking table tests show that SFS21 system behaves as intended. The response of the system can be predicted closely by using the analytical model shown in the paper.
