CIVIL-122: Structures I

Le cours présente les bases du comportement des structures, de la détermination des efforts qui y agissent et les principes de leur dimensionnement. Le cours est basé sur la résolution des efforts par la statique graphique. ...

Description

This lecture covers the analysis of cables with distributed loads, focusing on determining the self-weight of the cable and the maximum forces at different points. The instructor explains the impact of equal charges placed at specific distances along the cable, providing calculations and examples.

Instructor

Olivier Burdet

Born 1960, Olivier Burdet has received his Diploma in Civil Engineering from EPFL in 1983. After a couple years in engineering practice, he went back to studying at the university of Texas at Austin, where he received his PhD in 1990. Returning to EPFL in 1990, he is now a senior researcher and a lecturer in the field of reinforced concrete structures. He is also actively involved in the development of internet-based course contents and MOOCs.

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.

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.

Weight loss

Weight loss, in the context of medicine, health, or physical fitness, refers to a reduction of the total body mass, by a mean loss of fluid, body fat (adipose tissue), or lean mass (namely bone mineral deposits, muscle, tendon, and other connective tissue). Weight loss can either occur unintentionally because of malnourishment or an underlying disease, or from a conscious effort to improve an actual or perceived overweight or obese state.
