    Abstract: An intelligent generation and analysis system of trusses isbuilt. It can complete the process of layout, topological generationand calculation for truss structures automatically. The layout design oftrusses include joints setting and selective bar connecting. Thestructure is formed automatically by use of the topological variationmethod. The basic internal force matrix is adopted to analyze the structure.Examples show that this proposed system enjoys a good performance and is easy tooperate. The system is characterized with intelligent and self-adaptiveabilities. It can help to realize the topology and layout optimization designof structures.
