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

| Keywords: | truss topological variation layout choice basic internal forces matrix intelligence topology and layout optimization |
