Intelligent modularization for scalable concrete construction by adaptation of the methods for modular construction development

模块化施工与施工套件系统相结合，结合了高性能材料预制混凝土构件的连续流水作业生产及其在连续数字模型中的表示，由于施工时间短，节段细长，为传统的钢筋混凝土施工方法提供了一种节省资源和经济的选择。在研究项目的第一个资助期，研究了将开发机械工程使用的模块化系统的基本方法论概念转移到直结构的土木工程问题上。以框架结构模块细分为例，探索了实现外部大(建筑物多)、内部变化小(模块变体少)的方法。为了解决这一研究问题，产品开发研究所(IPEC)开发了一种模块化系统的优化方法，该方法考虑了建筑结构、材料和节点数量的要求。它能够识别易于运输和组装的资源节约型模块变体。混凝土结构与建筑材料研究所(IMB)用理论和试验相结合的方法研究了由模块组成的刚架结构。特别是，初步研究了干缝中的力传递、集中荷载以及预应力组合构件的受力性能。第二个资助期的目标是研究用于建筑施工的新型模块化系统，通过同时使用曲面结构构件使建筑具有很大的多样性。根据第一个资助期的结果，对中间构件进行了调查，这些中间构件用于建立具有部分直梁和板单元的曲面构件(平面内和平面外)。此外，还探讨了将专门用于一次性用途的部件纳入模块化系统以及制定相关规则和标准的问题。IPEC开发了评估组件是否应作为模块或特殊组件包括在模块化系统中的方法。在此基础上，探讨了包括曲线结构在内的框架结构模块化系统的体系结构、模块和模块变体。在多轴荷载作用下，对高性能材料节点进行了理论和实验研究。此外，还探索了材料、预应力和连接技术，通过使用直的规则构件和中间构件施加预应力来建立曲线形状的承重结构，这些构件可以重复使用。满足这一研究项目的目标将节省资源、时间和建设成本。这两个研究所的跨学科合作促进了产品开发机构和混凝土结构机构之间的知识转移。

Modular construction with construction kit systems in combination with serial flow production of prefabricated concrete members made of high-performance materials and their representation in continuous digital models offers a resource saving and economical alternative to conventional reinforced concrete construction methods due to short construction times with slender segments. In the first funding period of the research project, the transfer of basic methodical concepts to develop modular systems used by mechanical engineering to civil engineering problems was investigated for straight structures. For the example of frame construction subdivided into modules, methods were explored to achieve a large external (many buildings) with small internal variety (few module variants). To solve this research question, the Institute of Product Development (IPEK) developed an optimisation approach for modular systems that takes into account requirements of building structures, materials and number of joints. It enables the identification of resource-saving module variants which are easy to transport and to assemble. The Institute of Concrete Structures and Building Materials (IMB) investigates rigid frame structures composed of modules with theoretical and experimental methods. In particular, initially the force transmission in dry joints, concentrated loading and the load-carrying behaviour of prestressed modularly assembled members were investigated. The objective of the second funding period is the research of novel modular systems for building construction, which enable a great architectural variety by means of curved structural members at the same time. Based on the results of the first funding period, intermediate components are investigated which are used to establish curved members (in-plan and out-of-plane) with partly straight beam and plate elements. Further, the integration of components for special single use purposes into the modular system and the formulation of the associated rules and standards are explored. IPEK develops methods for assessing whether a component should be included in the modular system as a module or as a special component. Furthermore, it is explored which architecture, modules and module variants are essential for a modular system for frame buildings including curved structures. At IMB, nodes made of high-performance materials under multi-axial loading are investigated using theoretical and experimental methods. In addition, materials, prestressing as well as joining techniques are explored to establish load-bearing structures with curved shapes by prestressing using straight regular and intermediate components, which are reusable for further applications. Meeting the objectives of this research project will allow for resource, time and construction cost savings. The interdisciplinary collaboration of both institutes promotes the transfer of knowledge between institutions of product development and concrete structures.
