Reliability-based risk factors

  • David G. Elms University of Canterbury, Christchurch, New Zealand


Risk factors are used in some codes to allow for the
 higher than normal consequences of the failure of essential
or important structures. A classification of high-risk structures is given, based on different reasons for high importance. Risk factors are then related to reliability factors, defined as the increases in reliability required compared with that for a normal building. By assuming reasonable values for reliability factors, a set of risk
 factors is derived. Some of these correspond closely to those specified in the New Zealand code, while others differ markedly.
