Knowledge-based approach for composite floor system design

A prototype knowledge-based expert system developed for design of composite floor systems in multistory buildings is discussed. The design system is in accordance with the 1986 American Institute of Steel Construction (AISC) load and resistance factor design (LRFD) specification. Design options include design for practical minimum cost or for minimum depth. The artificial intelligence (AI) technology complements the traditional numerical processing in automating the complex problem of integrated engineering design and developing intelligent software packages that can interact with the user at a high level.<>
