Description

This lecture covers the design of folded plate structures in timber, focusing on historical examples, structural principles, origami patterns, fabrication of timber joinery, and full-scale prototype testing. The instructor discusses various forms of folded systems, such as deployable and static structures, and explores different patterns like corrugated surfaces and origami. The lecture also delves into the fabrication of timber joinery, including interlocking folded plate structures and different types of connections. Additionally, it examines the rotational stiffness of joints in folded plate structures and the setup for testing wood joint stiffness. The presentation concludes with a detailed analysis of a full-scale prototype test of a folded plate structure in timber.

In MOOC

Advanced Timber Plate Structural Design

The proposed MOOC intends to foster trans-disciplinary design approach in Architecture, Engineering, and Construction (AEC) for timber structures. It outlines an innovative and sustainable methodology with examples from recent construction projects. The primary development goal for this MOOC is to spread the innovative design approach in AEC we developed at EPFL. Therefore, the MOOC results from the compilation of five doctoral theses, research-industry technology transfer with our industry partner, and a

Structural engineering

Structural engineering is a sub-discipline of civil engineering in which structural engineers are trained to design the 'bones and muscles' that create the form and shape of human-made structures. Structural engineers also must understand and calculate the stability, strength, rigidity and earthquake-susceptibility of built structures for buildings and nonbuilding structures. The structural designs are integrated with those of other designers such as architects and building services engineer and often supervise the construction of projects by contractors on site.

Structural mechanics

Structural mechanics or mechanics of structures is the computation of deformations, deflections, and internal forces or stresses (stress equivalents) within structures, either for design or for performance evaluation of existing structures. It is one subset of structural analysis. Structural mechanics analysis needs input data such as structural loads, the structure's geometric representation and support conditions, and the materials' properties. Output quantities may include support reactions, stresses and displacements.

Timber framing

Timber framing (Holzfachwerk) and "post-and-beam" construction are traditional methods of building with heavy timbers, creating structures using squared-off and carefully fitted and joined timbers with joints secured by large wooden pegs. If the structural frame of load-bearing timber is left exposed on the exterior of the building it may be referred to as half-timbered, and in many cases the infill between timbers will be used for decorative effect.

Structural bioinformatics

Structural bioinformatics is the branch of bioinformatics that is related to the analysis and prediction of the three-dimensional structure of biological macromolecules such as proteins, RNA, and DNA. It deals with generalizations about macromolecular 3D structures such as comparisons of overall folds and local motifs, principles of molecular folding, evolution, binding interactions, and structure/function relationships, working both from experimentally solved structures and from computational models.

Structure

A structure is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized. Material structures include man-made objects such as buildings and machines and natural objects such as biological organisms, minerals and chemicals. Abstract structures include data structures in computer science and musical form. Types of structure include a hierarchy (a cascade of one-to-many relationships), a network featuring many-to-many links, or a lattice featuring connections between components that are neighbors in space.
