CENV2024 Structural Design and Materials

Module Overview

You will learn how to apply the theoretical principles of structural mechanics learnt during your first year to the design of real life structures. You will learn the fundamental aspects of steelwork design with an emphasis on buckling. The design of reinforced concrete beams will be covered, as well as the design of timber and masonry structures. The selection of appropriate materials is vital skill for practicing civil/structural engineers and you will learn the underlying science behind the structural performance and durability of the main materials used in the built environment. This will include an emphasis on steel metallurgy and welding.

Aims and Objectives

Module Aims

To demonstrate knowledge and understanding of the properties, uses and problems of the most common construction materials including concrete, masonry, metals, timber, plastics, paints and bituminous materials. You will consider the properties of these materials, including issues related to long term durability, as well as sustainability and recycling. You will be taught the theory of design from first principles but in the context of the Eurocodes. The philosophy underpinning modern structural design will be examined, as will the use of partial safety factors to ensure safety. You will learn how to design commonly occurring structural components, such as steel, reinforced concrete and timber members. An understanding of how structural components fit together to form a co-ordinated framework will also be acquired. You will be taught how to calculate the loading to individual structural components and how these loads transfer through structures to the foundations via load paths. You will be expected to recognise these principles in existing structures and you will be shown how to relate these principles to the structures you have built during the Constructionarium in Part 1.

Special Features

Design, build, test laboratory class where students will design and manufacture a truss and then test it to destruction.

Learning and Teaching

Teaching and learning methods

The module will include 3 lectures per week for 12 weeks. A range of design examples will be presented to explain the application of the theory to real design situations. An extensive range of tutorial questions will be provided for each topic and these will be accompanies with solution sheets which will enable you to practice and develop your understanding during your own private study time in preparation for the examination.
