Anti-Vibration Performance Proof Test for an Optimized Stiffness Distribution of Elasto-Plastic Joint Elements for Boiler Structures

Seismic ties are the connecting devices installed between a boiler and its supporting structure in thermal power plants. The seismic ties are made of steel and allowed to be used in the elasto-plastic deformation region in order to reduce the seismic response of the boiler structure. This paper deals with an anti-vibration performance proof test for an optimized stiffness distribution of elasto-plastic joint elements for boiler structures using a down-scaled boiler structure model on a large shaking table.
