Description

This lecture covers the design and assembly process of a double-layer free-form shell structure, focusing on advanced timber plate structural design, including the optimization of force flow and stress distribution. The instructor presents the development of a prototype and the use of custom CAD plugins for fabrication. Various design patterns and connection details are discussed, along with the structural analysis of the shell. References to related research works are provided.

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 analysis

Structural analysis is a branch of solid mechanics which uses simplified models for solids like bars, beams and shells for engineering decision making. Its main objective is to determine the effect of loads on the physical structures and their components. In contrast to theory of elasticity, the models used in structure analysis are often differential equations in one spatial variable. Structures subject to this type of analysis include all that must withstand loads, such as buildings, bridges, aircraft and ships.

Structural engineer

Structural engineers analyze, design, plan, and research structural components and structural systems to achieve design goals and ensure the safety and comfort of users or occupants. Their work takes account mainly of safety, technical, economic, and environmental concerns, but they may also consider aesthetic and social factors. Structural engineering is usually considered a specialty discipline within civil engineering, but it can also be studied in its own right.

Design pattern

A design pattern is the re-usable form of a solution to a design problem. The idea was introduced by the architect Christopher Alexander and has been adapted for various other disciplines, particularly software engineering. An organized collection of design patterns that relate to a particular field is called a pattern language. This language gives a common terminology for discussing the situations designers are faced with. The elements of this language are entities called patterns.

Connection form

In mathematics, and specifically differential geometry, a connection form is a manner of organizing the data of a connection using the language of moving frames and differential forms. Historically, connection forms were introduced by Élie Cartan in the first half of the 20th century as part of, and one of the principal motivations for, his method of moving frames. The connection form generally depends on a choice of a coordinate frame, and so is not a tensorial object.
