摘 要：This paper proposed a hierarchical architecture of steel house materials. The proposed architecture will include the detailed information of the components. For this, we made description about steel house design method and material change task ontology. Especially AFM is composited with total four steps. Using the method, the solution process of possible problems occurred in a steel house can be converted to an otology. Also we made category about composite patterns of steel house materials.
