RESEARCH ON MODELING AND OPTIMIZATION PROGRAM OF LONG-SPAN HYBRID GRID HANGAR BASED ON LEVERAGE PRINCIPLE


 A long-span hybrid grid hangar structure and a modeling method for the based on principle of leverage are proposed in this paper. Based SAP2000 spatial design software, C# language was used to develop plug-in automatically create leverage, which realized automatic generation by inputting parameters such as span structure, number horizontal grids, vertical grids. The optimization particle swarm algorithm is proposed. software program leverage. carried out, results show that can reduce thickness roof displacement at opening basis meeting current specifications.
