Description

This lecture presents a prototype of a single-curved timber shell, expanding the design space from folded geometries to low curved arches. The structure, with a 25-meter span, consists of two layers of timber plates connected with tenon wood-wood connections. The use of a Miura-ori pattern, quad grid, and triangulation technique in the design process is discussed, along with the application of Shape-Up algorithm to determine the final form and local geometry of the structure. The lecture also covers the optimized mechanical performances of the structural system, particularly focusing on the wood-wood connections' ability to transfer forces and moments without additional connectors.

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

Geometry

Geometry (; ) is a branch of mathematics concerned with properties of space such as the distance, shape, size, and relative position of figures. Geometry is, along with arithmetic, one of the oldest branches of mathematics. A mathematician who works in the field of geometry is called a geometer. Until the 19th century, geometry was almost exclusively devoted to Euclidean geometry, which includes the notions of point, line, plane, distance, angle, surface, and curve, as fundamental concepts.

Differential geometry

Differential geometry is a mathematical discipline that studies the geometry of smooth shapes and smooth spaces, otherwise known as smooth manifolds. It uses the techniques of differential calculus, integral calculus, linear algebra and multilinear algebra. The field has its origins in the study of spherical geometry as far back as antiquity. It also relates to astronomy, the geodesy of the Earth, and later the study of hyperbolic geometry by Lobachevsky.

Non-Euclidean geometry

In mathematics, non-Euclidean geometry consists of two geometries based on axioms closely related to those that specify Euclidean geometry. As Euclidean geometry lies at the intersection of metric geometry and affine geometry, non-Euclidean geometry arises by either replacing the parallel postulate with an alternative, or relaxing the metric requirement. In the former case, one obtains hyperbolic geometry and elliptic geometry, the traditional non-Euclidean geometries.

Structural system

The term structural system or structural frame in structural engineering refers to the load-resisting sub-system of a building or object. The structural system transfers loads through interconnected elements or members. Commonly used structures can be classified into five major categories, depending on the type of primary stress that may arise in the members of the structures under major design loads. However any two or more of the basic structural types described in the following may be combined in a single structure, such as a building or a bridge in order to meet the structure's functional requirements.

Euclidean geometry

Euclidean geometry is a mathematical system attributed to ancient Greek mathematician Euclid, which he described in his textbook on geometry, Elements. Euclid's approach consists in assuming a small set of intuitively appealing axioms (postulates) and deducing many other propositions (theorems) from these. Although many of Euclid's results had been stated earlier, Euclid was the first to organize these propositions into a logical system in which each result is proved from axioms and previously proved theorems.
