Outline of Final Research Achievements

Modeling and seismic response analysis of large-scale machines and pipings subjected to seismic input was performed. The seismic design method of machines and pipings for the huge earthquake input is investigated on the basis of probability theory. First, response of pipings subjected to several seismic inputs and response of pipings supported by gap support were calculated. Furthermore, the reduced order model with high accuracy of response was also introduced. The evaluation index for the risk assessment are proposed and the supporting methods to reduce the seismic damage were investigated.
