Details	In this research, complicated response characteristics of these roof and RC walls are made clear. The real scale mock-up experiments of PTFE sliding bearings, friction damper bearings, and rubber sheet bearings are carried out, followed by the shaking table test for seismically isolated roofs. From these results, detailed construction methods for eliminating the damages without strengthening the roof, followed by proposing the evaluation methods. Also the steel roofs supported by seismic isolation bearings are investigated, followed by shaking table tests and response evaluations.
