Description

An analytical method for constructing seismic fragilities of piping systems is proposed. The input earthquake can be described by its spectral density matrix, which is more general than a time history. The presence of multiple cracks at a critical section is considered in the calculation of the failure probability. The effectiveness of the method is demonstrated with examples, showing also that the influence of the correlation coefficients between the support motions depends on the rigidity of the piping system.
