The basic principle of conventional earthquake‐resistant design is to ensure an acceptable safety level while avoiding catastrophic failures and loss of life. When a structure does not collapse during a major earthquake, and the occupants can evacuate safely, it is considered that this structure has fulfilled its function even though it may never be functional again. Generally, this approach can be considered adequate for most types of structures. However for important structures, safer methods are required, while keeping economic factors in mind. For example, avoiding collapse is not sufficient for facilities that must remain functional immediately after an earthquake: hospitals, police stations, communication centers, and so on.
