Teaching/Supervision

Teaching

Dr Cashell is engaged in teaching and project supervision at undergraduate and postgraduate level.

  • CE 3001 Structural Analysis (module leader)

    The general aims of this course are to develop:
    • An intuitive understanding of structural behaviour;
    • Methods for the determination of various load effects;
    • Appreciation of different types of structures and their behaviour.
    The main focus is on statically indeterminate structures. That is, structures that cannot be solved for using the equations of statics alone. Students are introduced to several fundamental techniques of structural analysis including force methods, displacement methods and plastic analysis. Dr Cashell teaches for one term of this module.
  • CE 5603 Advanced steel design (module leader)

    The main aims of this module are:
    • To introduce the concept of advanced steel design and composite construction and their applications in engineering.
    • To develop in depth understanding of the behavioural and theoretical background to limit state design of structural steelwork.
    • To be able to design multi-storey steel frames including braced steel frame and steel-framed composite buildings; o To understand the stability analysis of steel structures.
    Dr Cashell teaches all of this module.
  • CE 3003 Steel and Concrete Design (module contributor)

    The primary aim of this course is to provide an introduction to the behaviour and design of reinforced concrete and steel structures. Dr Cashell teaches for one term on the subject of structural steelwork design. This covers the design of steel tensions members, compression members, steel beams including web bearing and web buckling, steel beam-columns, joints/connections, principles of member sizing, serviceability limit state design of steel beams and general principles of steel frame design.
  • CE 3009/3099 Individual Project (module leader)

    Dr Cashell coordinates the final year projects and also supervises a number of projects. The main aims of this module are as follows:
    • To give experience in planning, researching and conducting a major civil engineering project;
    • To apply relevant civil engineering techniques to an in-depth level; o To assess the validity of the results and carry out an in-depth analysis;
    • To critically assess the findings in the light of engineering applications and in comparison with previous work;
    • To develop self-direction in finding solutions, putting forward ideas and draw conclusions;
    • To apply and improve transferable skills.
  • CE 1601 Fundamentals of structures (module contributor)

    This module covers most of the core topics on fundamentals of structural and applied mechanics.

    The aims are to:
    • establish a solid foundation in the basic concepts of mechanics, kinematics and kinetics of particles and systems of particles;
    • extend these concepts to the foundation and principles of governing the mechanics of solid bodies under static and dynamic conditions.
    Dr Cashell contributes a number of lectures to this module.
  • CE 3604 Innovative construction materials (module contributor)

    The aims of this module are
    • To provide an introduction to innovative construction materials (ICMs); o To broaden and deepen students’ knowledge of the range and application of innovative construction materials;
    • To give an appreciation of the strengths and limitations of innovative construction materials;
    • To provide an appreciation of the selection and performance of innovative materials;
    • To give an appreciation of sustainability issues related to innovative construction materials;
    • To develop awareness of the latest developments and trends in the production and use of innovative construction materials.
    Dr Cashell contributes a number of lectures to this module.
