Expectation of Study on Reliability of Complex Aseismic Engineering Systems with Intermediate State before Failure under Failure-dependence
Peng Zhang · Journal of Sichuan University · 2003
The state of study on the failuredependence and generalized reliability theory for engineering structures and systems is discussed. Some limitations of applied researches are analyzed. On the basis of above, the notion is proposed that structures and systems take on three work modes i.e. safety, intermediate and failure states. The concept of reliability vector of engineering structures and systems with intermediate state is brought forward. According to characteristic of structures acted by a stochastically disturbing source of seismic load, a practical method for dealing with failuredependence of aseismic engineering systems is advanced by introducing dependence parameter, rules of norm operation and conditional probability. Some practical analysis methods for reliability vector of multilevel hierarchical and network aseismic engineering systems with intermediate state and failuredependence are established.
