A new paper with findings from 30 push-off tests conducted on dry-dry timber-concrete composite (TCC) notched connections designed for disassembly! ♻ I am happy to announce that our latest research paper, “Experimental investigations of dry-dry timber-concrete composite notched connections designed for disassembly” is now available in Elsevier’s Journal Engineering Structures. The full-text paper is open access and can be found here: 👉 https://lnkd.in/dGzKtxFp 👈 The paper presents a deconstructable dry-dry notched connection made from fully prefabricated concrete and timber elements, allowing for material reuse 🔧. The concept was experimentally investigated through pure-shear push-off tests, where various design parameters, such as fastener placement, notch length, and prestressing degree, were varied 📐. The experimental results indicate that the new connection exhibits the same structural properties as a traditional wet-dry notched connection despite being more environmentally friendly. Throughout the campaign, a comprehensive set of data 📊 was collected for each specimen and used for an in-depth analysis of the structural behavior. All this data is now available from the DTU data repository: 👉 https://lnkd.in/dgcf65vr 👈 Special thanks to my esteemed co-authors Jesper Harrild Sørensen (DTU Construct), Linh Cao Hoang (DTU Construct), Bent Feddersen (Ramboll), and Finn Larsen (WSP). Furthermore, I want to thank Heidelberg Materials Precast Denmark A/S, who produced and sponsored the prefabricated concrete elements, as well as Erlend André Hall, Emil Mork, Daniel Ertresvåg, who helped conduct the experimental work as a part of their Master Thesis. The experimental work was performed at DTU Structural Lab. The paper is the second paper of my industrial PhD project, which would not have been possible without the financial support from Ramboll, Innovationsfonden, and Rambøll Fonden / Ramboll Foundation 👏 #TimberConcreteComposite #NotchedConnection #ExperimentalStudy #PureShear #Prefabrication #CircularConstruction #DesignforDisassembly #DTUConstruct #DTUStructuralLab #Ramboll
Stærkt Peter 💪 Er det fremtidens bæredygtige byggesystem? 😊 Jacob Ettrup Petersen
Det er så fedt det du har gang med den PhD, Peter. Godt gået! Og som altid perfekte (og nu også interaktive) illustrationer 🙌
Fedt Peter👍
Stort tillykke med udgivelsen! Fed illustration 😊
Godt gået Peter, det bliver spændende at læse!

8moDigital image correlation (DIC) and fastener force measurements provided valuable insights into the structural behavior both pre-failure and post-failure. An example can be seen in this animation, where DIC is used to map the crack pattern in the concrete at failure, revealing that the Concrete Shear Failure occurred partly through an existing crack.
