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 concept of equilibrium in the plane, focusing on the balance and friction of skiers. Students are required to draw force diagrams for skiers, position forces, and indicate their values. The lecture emphasizes the importance of extending forces in polygons and using subsystems to express balance. It also includes instructions for printing exercise sheets and managing page layouts. Additionally, the lecture provides information on structural courses at EPFL, including topics like beams, slabs, and loads. Students are encouraged to engage with course materials and exercises to develop an intuitive understanding of structures.

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 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 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 integrity and failure

Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs. Structural integrity is the ability of an item—either a structural component or a structure consisting of many components—to hold together under a load, including its own weight, without breaking or deforming excessively.

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.

Printing

Printing is a process for mass reproducing text and images using a master form or template. The earliest non-paper products involving printing include cylinder seals and objects such as the Cyrus Cylinder and the Cylinders of Nabonidus. The earliest known form of printing as applied to paper was woodblock printing, which appeared in China before 220 AD for cloth printing. However, it would not be applied to paper until the seventh century.
