Structural Design - 2019 entry

A good knowledge of the philosophies and techniques of structural design and analysis are essential elements of the training of civil engineers. In this module you will learn about these philosophies, methodologies and techniques, and their application to the design of steel, reinforced concrete, and pre-stressed concrete structures. You will learn about factors such as elasticity, cracking, tensile strength, shear and flexure, through observation and analysis. You will complete two design projects, one in steel, one in concrete, and will get the chance to carry out calculations, sketch and exercise critical judgements.

Furthermore, you will get the opportunity to hone your skills in methods of structural analyses, technical report writing and presentation.  In addition, the module emphasises the role of the Codes of Practice (e.g. Eurocodes), the application of engineering judgement, and the execution of appropriate structural analyses in the context of design problems.

This module aims to give you a grounding in methods of analysis for both linear elastic and plastic modes of behaviour, and to help you gain an understanding of how engineers apply these methods to the design of real structures. It focuses particularly on steel, reinforced concrete, and prestressed concrete, materials that are often used in civil engineering, despite their complex properties. You will learn how, for this reason, simplified but realistic engineering approaches are required for design purposes. In addition, the module aims to help you appreciate the limitations of these methods, to understand the underlying philosophies of current professional Codes of Practice, and to gain competence in using appropriate methods for the design of simple structures.
