Improved Importance Sampling Methods for Structural System Reliability Calculation

by Robert E. Melchers, Univ of Newcastle,



Document Type: Proceeding Paper

Part of: Structural Safety and Reliability

Abstract: Improvements can be made to importance sampling by recognising some of the essential features of the time-independent structural reliability problem. Thus non-interesting regions in the integration domain can be deleted from consideration using a priori information and updating techniques. These can also be used to obtain the point(s) of maximum likelihood, a central parameter for importance sampling in cartesian co-ordinates.
