Abstract:

This report reviews and discusses several procedures for designing structures to resist earthquake shaking. The cost of strengthening structures is presented, and the damage expected from earthquakes is discussed. A least-total-cost analysis is presented which leads to optimal design acceleration levels. Navy economic analysis techniques were used to evaluate present worth of damage and cost. Results are presented in terms of least-cost design levels as a function of site earthquake acceleration levels having a probability of not being exceeded in 50 years. Also given is the marginal cost per life saved for the present Naval Facilities Engineering Command design level over the optimal level. Results indicate that a reduction in design level is possible.
