项目摘要

Space frame structures belong to the core innovations in structural design and are therefore an important part of the heritage of modernity. They have been used in manifold applications and combine structural economy with diversity in design. The development of space frame structures has significantly been driven in Germany by Max Mengeringhausen as a pioneer who, already in the 1920s, developed the well known MERO system consisting of connection nodes and tubular rod elements. Based on this revolutionary invention of the modern era, both the MERO space frame system and similar developments spread out all over the world during the second half of the 20th century. Due to the immense efficiency of space frame structures, also the GDR was highly interested in developing competitive systems. Despite their prevalent use in the period after the second world war only little attention has been spent to these structures. Neither their architectural and constructional history has been sufficiently investigated, nor they have been subject of conservational research. Indeed, historical space frame structures of the 20th century are a challenge for conservationists. Despite their durability, the structures often do not satisfy all current requirements with respect to structural integrity or have been dissembled by specific reasons.Aim of this research project is to work out the historical development and the architectural and constructional significance of space frame structures that were erected from the 1920s to the 1970s in Germany. Beside the fundamental research in constructional history and structural conservation forming the base for an integral evaluation of space frame structures as significant part of the modernity’s heritage, the research project aims objectives of structural conservation. Accordingly, also strategies for the preservation of space frame structures considered as representatives of technical heritage will be developed. One important aspect in this context is the satisfaction of functional requirements and structural safety. In this context, one focus of the research project is put on the development of a methodology for the identification of internal forces in existing space frame structures. Further, a procedure that supports the selection of an optimal concept for structural strengthening as well as a respective guideline will be compiled.The topics of the proposed research project span over all three thematic sections of the DFG Priority Programme "Cultural Heritage - Structure" and will be elaborated in an interdisciplinary collaboration. The research in structural history will be based on classical literature and archive research as well as on architectural surveys, while the topics primarily related to engineering will use numerical and experimental techniques of structural dynamics, system identification and optimization. The base for these research activities is given by preliminary work of the proposer.
空间框架结构属于结构设计的核心创新,因此是现代性遗产的重要组成部分。它们已被用于多种应用,并将结构经济性与设计多样性结合起来。德国空间框架结构的发展受到 Max Mengeringhausen 作为先驱的大力推动,他早在 20 年代就开发了众所周知的 MERO 系统,该系统由连接节点和管状杆元件组成。基于这一现代革命性的发明,MERO空间框架系统和类似的发展在20世纪下半叶遍布世界各地。由于空间框架结构的巨大效率,东德也对开发有竞争力的系统非常感兴趣。尽管它们在第二次世界大战后的时期被广泛使用,但人们对这些结构的关注却很少。它们的建筑和建造历史都没有得到充分的调查,也没有成为保护研究的对象。事实上,20 世纪的历史空间框架结构对环境保护主义者来说是一个挑战。尽管它们具有耐久性,但这些结构通常不能满足当前结构完整性方面的所有要求,或者由于特定原因而被拆除。该研究项目的目的是了解德国 1920 年代至 1970 年代建造的空间框架结构的历史发展以及建筑和构造意义。除了建筑历史和结构保护方面的基础研究构成对作为现代遗产重要组成部分的空间框架结构进行整体评估的基础之外,该研究项目还以结构保护为目标。因此,还将制定被视为技术遗产代表的空间框架结构的保护策略。在这方面的一个重要方面是满足功能要求和结构安全。在此背景下,该研究项目的一个重点是开发一种识别现有空间框架结构内力的方法。此外,还将编制支持选择结构加固最佳概念的程序以及相应的指南。拟议研究项目的主题涵盖 DFG 优先计划“文化遗产 - 结构”的所有三个主题部分,并将通过跨学科合作进行详细阐述。结构历史的研究将基于古典文献和档案研究以及建筑调查,而主要与工程相关的主题将使用结构动力学、系统识别和优化的数值和实验技术。这些研究活动的基础是提案者的前期工作。
