Timing and Structure
Michaelmas Term. 16 Lectures.
The aims of the course are to:
- Provide a general understanding of the relationship between the properties of common structural materials, and the principles and approaches underpinning their use in structural design
- Provide a bridge between the fundamental general engineering understanding of structures and materials developed in Part I and the applied specialist modules of Part II
- Provide knowledge and knowhow enabling structural designers to improve our use of energy and material in the design of the built environment while providing safe, useful structures for people to use
As specific objectives, by the end of the course students should be able to:
-  Use the lower-bound theory of plasticity to perform load-path design of structural arrangements and to appreciate the benefits and limitations of the approach
-  Consider the influence of risk, and variability of loading and material properties, in structural design and calculation
-  Explain the environmental impacts of structural material and design choices
-  Understand and carry out early-stage structural design with various structural materials
- [4.1] Identify the theoretical and practical considerations governing structural design in various materials and explain how these may be accommodated in design
- [4.2] Make reasonable conceptual design decisions regarding appropriate structural form, initial layout and initial member sizing for simple structures in various materials;
- [4.3] Perform preliminary technical design calculations for simple structures in various materials
- [4.4] Determine what design approaches may be appropriate, and what calculations necessary, for more complex structures in various materials
The course this year will be 'blended', meaning that a mix of in-person, online live (Teams) and online recorded (Moodle) components will be used. We plan to deliver some of our lectures in-person in the department (although these will also be recorded and subsequently uploaded to Moodle). We plan to deliver others remotely through a combination of recorded lectures and 'live' Q&As. Recorded lectures have been updated for this year and benefit from the many lessons we learned during 2020. Full details are available on the course Moodle page.
The implications of the general principles of structural mechanics – equilibrium, compatibility, constitutive laws, and stability – are investigated for different materials. This leads to discussion of typical structural forms in the various materials, the reasons for adopting them, and appropriate methods of construction. The significant types of structural behaviour, and therefore the most useful methods of analysis and calculation, are investigated for the different material types. Our basic aim is to establish means of making reasonable preliminary decisions about structural form, layout and initial sizing of structural members made from a range of common construction materials.
Design methodologies will be developed, and design of typical elements will be discussed, for:
- materials of low tensile but high compressive strength, such as masonry and glass;
- composite materials of low tensile strength combined with a ductile tensile material, such as reinforced concrete;
- high-strength, ductile materials such as steel and aluminium alloys;
- moderate- to high-strength, anisotropic, brittle materials such as engineered timber.
The critical modes of failure of structures made from these materials tend to differ, as do other considerations such as environmental impacts, so design approaches will be correspondingly different.

This lab will run in 'blended' form for 2021, with the morning session remote and the afternoon session in-person. Feedback from our first experience of running the lab in this way in 2020 was overwhelmingly positive, so we have changed very little this year. We retain the capability to run the afternoon session fully remotely, but we are hopeful that this will not be needed this year.

Details will be available on the course Moodle page early in the term.

The UK Standard for Professional Engineering Competence (UK-SPEC) describes the requirements that have to be met in order to become a Chartered Engineer, and gives examples of ways of doing this.
UK-SPEC is published by the Engineering Council on behalf of the UK engineering profession. The standard has been developed, and is regularly updated, by panels representing professional engineering institutions, employers and engineering educators. Of particular relevance here is the 'Accreditation of Higher Education Programmes' (AHEP) document which sets out the standard for degree accreditation.
The Output Standards Matrices indicate where each of the Output Criteria as specified in the AHEP 3rd edition document is addressed within the Engineering and Manufacturing Engineering Triposes.
