Abstract:

In this report we describe an application of artificial intelligence AI methods to structural analysis. We describe the development and partial implementation of an automated consultant to advise non-expert engineers in the use of a general-purpose structural analysis program. The analysis program numerically simualtes the behavior of a physical structure subjected to various mechanical loading conditions. The automated consultant, called SACON Structural Analysis Consultant, is based on a version of the MYCIN program Shortliffe 74 originally developed to advise physicians in the diagnosis and treatment of infectious diseases, The domain-specific knowledge in MYCIN is represented as situation-action rules, and is kept independent of the inference engine that uses the rules. By subsituting structural engineering knowledge for the medical knowledge, the program was converted easily from the domain of infectious diseases to the domain of structural analysis. Author
