Document Type: Proceeding Paper
Part of: Structural Materials
This paper develops and implements a methodology for predicting probabilistically the damage an offshore structure will experience in an earthquake. The analysis begins with the probability distribution for the waiting time to a given number of range-pair cycles due to a nonstationary Gaussian process. The distribution for range-pair cycles is related to the distribution for toplevel-up cycles. The waiting time distribution is then transformed into a distribution for the number of events in a given time. The probability distribution for the number of events is combined with the Manson-Coffin damage accumulation law to predict the expected damage.
