摘要

The Model Correction Factor Method is an intelligent response surface method based on simplified modeling. MCFM is aimed for reliability analysis in case of a limit state defined by an elaborate model. Herein it is demonstrated that the method is applicable for elaborate limit state surfaces on which several ocally most central points exist without there being a simple geometric definition of the corresponding failure modes such as is the case for collapse mechanisms in rigid plastic hinge models for frame structures. Taking as simplified idealized model a mdoel of similarity with the elaborate model but with clearly defined failure modes, the MCFM can be started from each idealized single mode limit state in turn to identify a locally most cnetral point on the elaborate limit state surface. Typically this procedure leads to a fewer number of locally most central failure points on the elaborate limit state surface than existing in the idealized model.
