This paper deals with seismic proof tests of the boiler structures in thermal power plant. After investigation of the damage on these structures by the Great Kobe Earthquake, the tests were conducted on the behavior of "Seismic Ties". They are connecting devices installed between the boiler and the supporting structure. The tests were carried out by using scaled model of boiler structure on a large shaking table. The seismic ties are made of steel and allowed to be used in the elasto-plastic deformation region. The seismic response can be reduced by the energy dissipation of the hysteretic deformation of the ties. It is confirmed that the validity of the seismic design for the boiler structure throughout the tests.
