This paper describes the research and development of the new type of isolation systems suitable for light-weight-houses. The Basic concept of the new isolation system is to realize cost effective design without any reduction in the isolation performance. This paper presents results obtained from experimental and analytical studies to evaluate isolation performance of the new isolation system. In the experiment, static tests were first carried out using a 0.20 scale model (55 kg mass, and 0.50m× 0.50m×0.27m size) for isolated-light-weight-houses model which was supported by two linear ball bearing and, restring force was given to superstructure by transversal stiffness of a coiled spring, so as to examine restring force characteristic for the coiled spring. Second, dynamic tests were implemented in order to investigate the isolation performance of the isolation system in actual seismic waves. In analysis, seismic response analyses for the scale model, regarding the vibration tests using the actual seismic wave, were carried out to evaluated the response analytical method for the isolation system using the coiled spring. From these results, the following are clarified. (1)Analytical results for the isolated-light-weight-houses model agree well with experiment results.(2)The isolated system using the coiled spring reduced responses acceleration sufficiently.
