Preliminary Mechanical Analysis of Relay Frame’s Reconstructed Support of Daya Bay Nuclear Power Station

Spectrum method was used for aseismatic analysis of relay frame support including rubber dashpot, Z support and U support reconstructed of Daya Bay Nuclear Power Plant, and relay frame support of Ling’ao Nuclear Power Plant. The aseismatic capability was compared before and after relay frame reconstruction under the same seismic load. It provides a reference for relay frame support’s renovation of Daya Bay Nuclear Power Station.
