Structural Analysis and 3D Timber Spatial Structure Modeling

The analysis of the structural form of the multi-volume dome structure using load-bearing wooden arches is performed. The complexity of the volumes and their connecting lines, as well as the requirement to conduct a non-linear analysis of long-span wooden elements at the request of Eurocode 5 make the information model necessary. It is noted that the design using this technology is developing in the direction of taking into account all stages of the structure  life cycle. Information modeling of wooden structures in the world is the most prepared for the use of BIM-technologies. This is due to the sophisticated digital technologies for the production   of modern wooden structures elements. An information model was formed for designing according to the regulations of Ukraine. The Information Model was created in the SAPFIR software package for further possibility of importing the model into the LIRA-CAD software package. The necessary auxiliary steps were used to build the model. The loads on the curved surface were calculated in the PC Espri. For further development of the nodes, 3D-modeling was used with the transfer of the information model into the PC Tekla Structures as a specialized environment for the constructive section of the project. The presented analysis of the complex dome structure using wooden arches summarizes the approaches to the development of unique forms of structures using wood. The use of information models has significantly increased the complexity of architectural design and structural model taking into account the nonlinear effects of wood. The possibility of integrating these tools for further implementation in BIM-technology is shown.
