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，采用高性能材料制成的预制混凝土构件的连续流水生产及其在连续数字模型中的表示，由于细长段的施工时间短，因此与传统的钢筋混凝土施工方法相比，提供了一种节省资源和经济的替代方案。 在研究项目的第一个资助期内，研究了将机械工程所用的模块化系统开发的基本方法概念转移到土木工程问题中的直线结构。对于框架结构细分为模块的例子，探索了实现大的外部（许多建筑物）和小的内部变化（几个模块变体）的方法。为了解决这个研究问题，产品开发研究所（IPEK）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，材料和接头数量的要求。它能够识别易于运输和组装的资源节约模块变体。混凝土结构和建筑材料研究所（IMB）用理论和实验方法研究由模块组成的刚架结构。特别是，最初的力传递干接缝，集中荷载和预应力模块化组装构件的承载行为进行了研究。第二个供资期的目标是研究用于建筑施工的新型模块化系统，同时通过弯曲的结构构件实现巨大的建筑多样性。根据第一个资助期的结果，研究了用于建立弯曲构件（平面内和平面外）的中间构件，其中部分为直梁和板单元。此外，还探讨了将用于特殊一次性用途的组件整合到模块化系统中以及制定相关规则和标准的问题。IPEK开发了用于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。此外，它是探索的架构，模块和模块的变体是必不可少的模块化系统的框架建筑物，包括弯曲结构。在IMB，多轴向载荷下的高性能材料制成的节点进行了研究，使用理论和实验方法。此外，材料，预应力以及连接技术进行了探索，以建立承载结构的曲线形状的预应力使用直的规则和中间组件，这是可重复使用的进一步应用。满足本研究项目的目标将节省资源，时间和建设成本。两个研究所的跨学科合作促进了产品开发和具体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.
