Research Project 3-2 (RP 3-2)

IntCDC Research Project 3-2 – Co-Design of Multi-Storey Timber Building Systems for Building Stock Extension

CO-DESIGN, ADAPTATION, INTEGRATION AND OPTIMISATION OF MULTI-STOREY WOOD BUILDING SYSTEMS FOR BUILDING STOCK EXTENSION

Achieving the sustainable development goals defined by the United Nations will require innovation and commitment from all industries. For the building sector, this means adopting more cost and energy efficient methods, reducing material waste and increasing the use of carbon neutral materials such as timber. This can be achieved through the development of co-design methods that integrate architectural, structural and building physics criteria in feedback with novel fabrication and construction capabilities in order to articulate timber building systems that overcome the typical limitations of multi-storey timber structures. Such quasi mono-material and future-proof wood building systems are based on standard timber materials (e.g. GLT or CLT) and offer open-purpose, multifunctional and geometrically bespoke column, wall and ceiling elements, thus achieving biaxial, variable-span and structurally optimised, resource-efficient solutions using on-site/off-site additive and subtractive manufacturing processes. This would enable independence from the typically constraining rigid grid ordering systems and promote new timber architectural typologies that are also attractive for long-term use through adaptability and flexible programming.

Based on the findings of the predecessor project RP 3-1, this project will address the next set of research challenges for the co-design methods and multi-storey timber building system developments by:

Extending the design space of the system towards the extension of the existing building stock by investigating and integrating design adaptation methods and flexible strategies for establishing performative interfaces with existing structures.
Investigating the potential for replacing remaining non-timber building system elements with timber-based solutions, thereby facilitating the integration of additional building elements into the existing building system, such as lateral bracing. This will include the investigation of bonded joints for energy dissipation capabilities and fire/high temperature resistance.
We will also extend the interdisciplinary modelling methods to other relevant parameters (e.g. fire resistance) and investigate multi-parameter optimisation methods and design frameworks beyond those developed in RP 3-1.
Finally, the research will establish a coordinated interdisciplinary project development process and a coherent computational design and engineering model through continuous synthesis. The resulting novel building system and methods will be demonstrated and evaluated through the building elements in the IntCDC demonstrator building. In parallel, we will evaluate the building stock extension method through benchmarking and synthesis studies.

The division of a surface using its PC lines into principal strips (PSs) is an innovative way to break down a freeform surface for construction. However, the application of PC networks in architectural design is hindered by the difficulty to generate them and flexibly control their density. This paper introduces a method for PS-based reconstruction of freeform surfaces with different umbilical conditions in the early stages of design. An agent-based modeling approach is developed to find the umbilics and increase the degree of control over the spacing of PC lines.

Constrained urban environments and building stock extensions are challenges for standard timber construction. Co-design promises to better integrate disciplines and processes, promising smaller feedback loops for design iteration and building verification. This article describes the integrated design, fabrication, and construction processes of a timber building prototype as a case study for the application of co-design methods. Emphasis is placed on the development of design and engineering methods, fabrication and construction processes, and materials and building systems. The development of the building prototype builds on previous research in robotic fabrication (including prefabrication, task distribution, and augmented reality integration), agent-based modelling (ABM) for the design and optimisation of structural components, and the systematisation of timber buildings and their components. The results presented in this article include a functional example of co-design from which best practises may be extrapolated as part of an inductive approach to design research.

The research uses quantitative methods to answer qualitative questions on the connection between architectural variety in timber construction and the stakeholders involved. Interconnectivity between stakeholders and projects is visualized in an interactive network graph. The study shows a segmented mass timber market with relatively few impactful design and construction stakeholders, mostly located in central and northern Europe.

  @article{Tapia_2023, abstract = {A new jointing concept for the vertical load transfer between glued laminated timber (GLT) columns in multi-storey timber buildings has been developed. The basic components of the connection are two stepped, pyramid-shaped inserts made from block-glued laminated veneer lumber (LVL), which are bonded oppositely into corresponding cavities of the jointed GLTs. The load transfer between the mating columns relies on an intermediate LVL pin, fitting into pyramid-type cavities. Beech LVL was chosen for both, insert and pin, due to its 2.2 times higher characteristic compressive strength as compared to the employed high-strength softwood GLT (GL32h). The form fit of the stepped components which are bonded together relies on high precision robotic milling and a gap-filling two-component polyurethane adhesive. Manufacturing and mechanical performance of the scalable connection was investigated with full-sized specimens, achieving up to 90% of the characteristic GLT compressive capacity of 1040kN for a cross-section of 180mm×180mm. A parametric model based on the finite element method (FEM) showed a good agreement with empiric strain distributions and provided a stress-spread angle of 35° for the concentrated vertical load for an analytical design approach. The location and magnitude of tensile stresses perpendicular to the grain causing splitting failure was identified by FEM. Reinforcement by self-tapping screws proved a significant load-capacity enhancement. The mean experimental axial compressive load capacity exceeded the analytical prediction by 19%. First investigations on the rotational stiffness delivered a value of 240kNm/rad. The column utilization due to additional directly supported floor slabs was assessed exclusively by FEM. The calculation results predict a significant reduction of the tensile stresses perpendicular to the grain to be verified experimentally.}, author = {Tapia, Cristóbal and Aicher, Simon}, doi = {https://doi.org/10.1016/j.engstruct.2023.116770}, issn = {0141-0296}, journal = {Engineering Structures}, pages = 116770, title = {A new concept for column-to-column connections for multi-storey timber buildings — Numerical and experimental investigations}, url = {https://www.sciencedirect.com/science/article/pii/S0141029623011859}, volume = 295, year = 2023 }

Although there has been a growing number of research focused on trends, benefits, and disadvantages in timber construction from various technical perspectives, so far there is no extensive literature on the trajectory of emerging architectural typologies. This paper presents an examination of architectural variety and spatial possibilities in current serial and modular multi-storey timber construction. It aims to draw a parallel between architectural characteristics and their relation to structural systems in timber. The research draws from a collection of 350 contemporary multi-storey timber building projects between 2000 and 2021. It consists of 300 built projects, 12 projects currently in construction, and 38 design proposals. The survey consists of quantitative and qualitative project data, as well as classification of the structural system, material, program, massing, and spatial organization of the projects. It then compares the different structural and design aspects to achieve a comprehensive overview of possibilities in timber construction. The outcome is an identification of the range of morphologies and a better understanding of the design space in current serial and modular multi-storey mass timber construction.}, article-number = {404}, author = {Svatoš-Ražnjević, Hana and Orozco, Luis and Menges, Achim}, doi = {10.3390/buildings12040404}, issn = {2075-5309}, journal = {Buildings}, number = 4, title = {Advanced Timber Construction Industry: A Review of 350 Multi-Storey Timber Projects from 2000–2021}, url = {https://www.mdpi.com/2075-5309/12/4/404}, volume = 12, year = 2022 }

  @article{Tapia_2022, abstract = {A new connection concept for joining cross-laminated timber (CLT) plates in their secondary direction is presented. The connection consists of two laminated veneer lumber (LVL) gusset plates with finger-joint-like profiles milled on one side which are glued onto the outermost layers of the CLT. It is demonstrated that the joint represents a stiff moment resistant connection, enabling the activation of the normally underutilized biaxiality of CLT plates and expanding the design freedom of architects and engineers. The concept was analyzed by means of analytical and finite element (FE) models for two geometry alternatives, differing in either a 2D or 3D tapered finger profile. The 3D tapered finger profile produced a stress reduction of around 5% in the region of stress concentration and a more even shear stress distribution on the bonded surface. Thereafter, four specimens were manufactured – two of each geometry alternative – and then tested in four- and three-point bending setups in order to assess the behavior at pure bending as well as at combined moment and shear loading, respectively. At pure bending, the studied connection delivered bending capacities of 100% of the characteristic value of the unjointed CLT material. For the case of moment and shear loading, the global capacity was determined by a bending failure in the CLT region subjected to maximum moment, while the joints remained unbroken. Measured deformations and strains during the tests validated the FE model, which can be used to further develop the connection concept, which allows for a full activation of the biaxial behavior of large-span CLT floors.}, author = {Tapia, Cristóbal and Claus, Marian and Aicher, Simon}, doi = {https://doi.org/10.1016/j.conbuildmat.2022.127645}, issn = {0950-0618}, journal = {Construction and Building Materials}, pages = 127645, title = {A finger-joint based edge connection for the weak direction of CLT plates}, url = {https://www.sciencedirect.com/science/article/pii/S0950061822013204}, volume = 340, year = 2022 }

These methods enable the production of tailor-made and differentiated building components that integrate design intention, robotic fabrication, structural performance, assembly logics and functional aspects but require advanced strategies to achieve and control production quality. We present methods to assure the quality control of the fast-paced production of the BUGA Wood Pavilion – a 500m² segmented wood shell structure - that was erected within 13 months from commission to opening. In this project, 376 bespoke hollow wood cassettes were robotically assembled, glued and milled to shapes. In order to achieve structurally performative tight-fit joints, minimal tolerances in the fabrication process needed to be achieved. Furthermore, the quality of the gluing interface, its tolerances, individual pressing forces, process- and environmental factors needed to be respected for the design and operation of robotic gluing processes to meet building regulations. New challenges arise for the design, management and control of production quality when co-dependent and integrated innovations are brought forward in respect to both building system as well as fabrication automation on a per- project level. Novel frameworks will need to be established that dwell on digital technologies for faster and more reliable process and quality control in timber construction.

  @inproceedings{Wagner2021, abstract = {In this paper we introduce a novel design to fabrication method called three-dimensional fibre placement in wood (3D-FPW) and demonstrate its applicability for lightweight hybrid timber structures. 3D-FPW allows for the joining and reinforcement through a combination of (1) minimally invasive subtractive CNC milling operations during the prefabrication of wooden building components and (2) the subsequent insertion of continuous fibrous materials to reinforce them and/or connect them on-site. Although natural fibres can be used for such technique, the presented work focuses on CFRP tows - that have a special advantage as they can be cured via electrical current in-place without oven or autoclave while the wood material acts both as insulator and formwork. The three-dimensional geometries of the discussed fibrous arrangements are hardly limited in their form which makes precise computational design strategies the cornerstone for an effective exploration, understanding and exploitation of the design potentials of such structures. We show how principal local stress-directions, fabrication specifications as well as design- and environmental considerations can be considered to form-find meaningful fibrous layouts within such structures. The proposed technique most notably creates novel performance-spectrums for sustainable, ultra-lightweight bespoke wood architecture by enabling tailor- made bending resistant on-site connections, that break free from added weight, expense and the intensive energy footprint of steel connectors. We further discuss our investigations within this framework through the prototypical fabrication of physical demonstrators that represent a comprehensive set of wood building system typologies: custom fibre-reinforced slab plates, a segmented plate shell structure and a polygonal lattice shell structure.}, author = {Wagner, Hans Jakob and Garufi, Dominga and Schwinn, Tobias and Wood, Dylan Marx and Menges, Achim}, booktitle = {Proceedings of the IASS Annual Symposium 2020/21 and the 7th International Conference on Spatial Structures}, editor = {Behnejad, S.A. and Parke, G.A.R. and Samavati, O.A.}, file = {:C\:/Users/ac128044/Google Drive/ICD_Wagner/01_Publikationen/1809_FIBRE_TIMBER/2107_IASS_Surrey/Paper Submission/IASS_3D_Fibre_Placement_in_Wood.pdf:pdf}, organization = {IASS }, title = {Three-Dimensional Fibre Placement in Wood for connections and reinforcements in timber structures}, venue = {Guilford (UK)}, year = 2021 }

ABxM.Core implements the functionality specific to agent-based modelling and simulation. The core library can, in principle, be referenced from any application that is compatible with McNeel’s Rhino.Inside technology.ABxM.Core defines four base classes for behaviors, agents, agent systems, and environments, and the Solver class. In addition to the base classes, the core library provides implementations for Vector-based systems called “Boid” (in reference to Craig Reynolds’ Boids), point-based systems called “Cartesian”, matrix-based systems (2d and 3d), mesh systems, and network systems. The necessary agent, system, environment, and behavior classes are derived from the corresponding base classes.Instructions for the use of the source code are included in the file "ABxM.Core-Further_instructions.pdf".}, affiliation = {Nguyen, Long/University of Stuttgart, Schwinn, Tobias/University of Stuttgart, Groenewolt, Abel/University of Stuttgart, Maierhofer, Mathias/University of Stuttgart, Zorn, Max Benjamin/University of Stuttgart, Stieler, David/University of Stuttgart, Siriwardena, Lasath/University of Stuttgart, Kannenberg, Fabian/University of Stuttgart, Menges, Achim/University of Stuttgart}, author = {Nguyen, Long and Schwinn, Tobias and Groenewolt, Abel and Maierhofer, Mathias and Zorn, Max Benjamin and Stieler, David and Siriwardena, Lasath and Kannenberg, Fabian and Menges, Achim}, doi = {10.18419/darus-2994}, howpublished = {Software}, note = {Related to: Groenewolt, A., Schwinn, T., Nguyen, L., & Menges, A.
