The Digital Building Kit - Simulation-based models and methods for the design of modular concrete structures, 2. phase

在第一个应用阶段，创建了一个连续的数字模型，即数字构建工具包，它使模块化结构设计中的基本问题得以澄清。这包括完整的设计链，从最初的初步设计，详细设计，静态力学模拟和设计到静态正确监控装配过程和施工进度。一个关键特征是使用和进一步发展参数化方法进行交互式、基于cad的设计、灵敏度分析和优化。这方面的技术基础是等几何分析及其进一步发展。在项目的下一阶段，将在模块化系统中解决详细的方法问题，以解决具体问题。这包括进一步发展和整合运动学和耦合公式，以便准确有效地建模结构细节，从而可以表示整个结构系统。此外，一个主要的焦点将是扩展基于三维体的等几何分析，以便能够设计几何复杂的部件。这些数值基础将用于使模块化结构的有效使用。为此，将开发方法来优化模块的结构效率和减少材料消耗。此外，有必要在给定的承重结构上实现各自模块边界的具体调整。最后，部件冗余度的确定是进一步研究的核心。尽可能均匀的冗余分布意味着负载传输的均等份额。相反，该信息可用于得出关于模块故障对系统剩余容量的影响的结论。基于对单个部件重要性的了解，可以定义设计公差或确定检查间隔。软件开发不断发布，并以开源的形式提供（Cocodrilo和Kratos Multiphysics）。下一阶段将继续与其他SPP伙伴进行良好的合作。项目合作伙伴的示范，特别是Menges教授和Sobek教授的小组，将用于扩展我们的方法，并以一致的模型呈现它们。此外，将采用标杆建筑施工来巩固我们的研究。

In the first application phase, a continuous digital model was created, the digital construction kit, which enables essential questions in the structural design of modular construction to be clarified. This includes the complete design chain from the first preliminary design, detailing, static-mechanical simulation and design to the statically correct monitoring of the assembly process and the construction progress. A key feature is the use and further development of parametric methods for interactive, CAD-based design, sensitivity analysis and optimization. The technological basis for this is the isogeometric analysis and the consequent further developments.In the next phase of the project, detailed methodological questions will be addressed in the modular system in order to solve specific problems. This includes the further development and integration of kinematic and coupling formulations in order to model structural details accurately and efficiently so that the entire structural system can be represented. Furthermore, a main focus will be the extension of 3D volume-based isogeometric analysis in order to be able to design geometrically complex components. These numerical fundamentals will be used to enable an efficient use of the modular structures. For this purpose, methods will be developed to optimize the modules for structural efficiency and reduced material consumption. Furthermore, it is necessary to implement specific adjustments of the respective module boundaries on given load-bearing structures. Finally, the component redundancy determination shall represent a further research core. A redundancy distribution that is as even as possible would mean an equal share of the load transfer. Conversely, this information can be used to draw conclusions about the consequences of a module failure on the residual capacity of the system. Based on the knowledge about the importance of individual components, tolerances for the design can be defined or inspection intervals can be determined.Software developments are published continuously and made available as open source (Cocodrilo and Kratos Multiphysics). The very good cooperation with the other SPP partners will be continued in the next phase. The demonstrators of the project partners, especially the groups of Prof. Menges and Prof. Sobek will be used to extend our methods and to present them in a consistent model. In addition, the benchmark building construction will be used to consolidate our research.
