Abstract
A rule-based damage assessment system of existing structures (SPERIL) subjected to earthquake excitation is described. The principal of inexact inference is applied to obtain a rational solution. Both the fuzzy set theory and a production system, with a certainty factor, are used jointly in the inexact inference to deal with the continuous nature of the damage state and to attain the modularity of uncertainty. An inference network diagram for the damage assessment of existing structures is included.
