Development of new structure design tools for buildings

在本研究中，新的结构设计工具，使用拓扑优化方法开发的建筑物的设计。在框架结构拓扑优化工具中，采用了基结构法，可以处理半直角连接。在二维结构和壳体结构的设计工具中，采用了均匀化设计方法。在三维结构建模工具中，采用了密度法和体素有限元法。在这些工具中，可以得到清晰的拓扑结构，因为一个有效的过滤方法被应用。此外，开发了图形用户界面，以便用于教育。在工具中采用了优化准则法和CONLIN法，以提高计算效率。这些软件将作为一本书与丸善的CD一起向公众开放。

In this study, new structure disegn tools using the topology optimization method were developed for the design of buildings. In the topology optimization tool for frame structure, the ground structure approach was used, and in this tool, semi-righd connections can be treated. In the tool for 2 dimensional structure and shell structure, the homogenization design method was used. In the tool for 3 dimensional structure, the density approach and voxel finite element method were used. In these tools, clear topology can be obtained, because an effective filtering method was applied. In addition, the graphic user interface was developed in order to use for the education. Also, the Optimality criteria method and CONLIN method were used in tools in order to improve the calculation cost. These software will be opened to public as a book with CD from MARUZEN.
