Seismic qualification using the updated finite element model of structures

Jyoti K. Sinha, A. Rama Rao and R. K. Sinha

Abstract

The standard practice is to seismically qualify the safety related equipment and structural components used in the nuclear power plants. Among several qualification approaches the qualification by the analysis using finite element (FE) method is the most common approach used in practice. However the predictions by the FE model for a structure is known to show significant deviations from the dynamic behaviour of
