Abstract

A Lego‐like steel‐framed structural system has been developed within the frame of an RFCS project, REDUCE, to facilitate 1) deconstruction of composite structures, 2) circularity at structure and element levels, and 3) serial production in construction by promoting a greater standardization of structural elements. The system utilizes innovative demountable shear connections for composite flooring solutions with precast concrete elements, and adjustable steel connections for use in both beam‐to‐beam and beam‐to‐column connections. The first use case of the structural system has been realized in the Petite Maison project which is a demonstration project for circularity and contributes to the event ESCH2022. Each construction element is linked to a digital database and remains available for future reuse, as a result of the plug‐and‐play, demountable and robust features of the developed system. This paper presents the proposed demountable system, the results from experiments and finite element analyses on the behaviour of shear connections, composite beams, and steel connections, and indicates the analysing methods for structural engineers to open a pathway for full implementation of the structures built into digital tools, fabrication, and construction.

一个类似乐高的钢框架系统，用于标准化和批量生产

在RFCS项目REDUCE的框架内开发了一种类似乐高的钢框架结构系统，以促进1）复合结构的解构，2）结构和元件层面的圆形性，以及3）通过促进结构元件的更大标准化，在施工中进行批量生产。该系统采用创新的可拆卸剪切连接件，用于具有预制混凝土元件的复合地板解决方案，以及用于梁与梁和梁与柱连接的可调节钢连接件。结构系统的第一个用例已经在Petite Maison项目中实现，该项目是圆形的示范项目，有助于ESCH2022事件。由于开发的系统具有即插即用、可拆卸和坚固的特点，每个结构元素都链接到一个数字数据库，并可供未来重复使用。本文介绍了所提出的可拆卸系统，剪切连接、组合梁和钢连接性能的实验和有限元分析结果，并指出了结构工程师的分析方法，为全面实现数字工具、制造和施工中的结构开辟了途径。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
