MEng Civil and Structural Engineering

This module will focus on structural concepts and structural dynamics. Structural concepts from theory to practice will emphasise on qualitative and intuitive analysis techniques. Much of the contents are based on the newly published book, Understanding and Using Structural Concepts, written by one of the two lecturers. Correct modelling will be demonstrated through plane problems. The other half of the module will deal with structural dynamics covering theoretical fundamentals to practical applications using a quantified approach. Students will use theoretical calculations, computational analysis and qualitative analysis techniques. This module will equip students with advanced structural knowledge to produce engineering solutions to real structural problems.

For students to gain an enhanced understanding of structural concepts and their applications, from structural elements to whole structures and from theory to application.

For students to understand plane problems and appropriate correct FE modelling of plane problems.

For students to understand the fundamentals of structural dynamics and the analysis of simple structures subjected to static and dynamic loads and to receive guidance on their applications.

The unit consists of 3 themes: Structural Concepts, FEM for Plane Problems and Structural Dynamics. These are supported by a 3 hrs lecture/tutorial/laboratory workshop per week for 12 weeks including 28 lectures, 6 tutorials and a 2 hrs computing laboratory workshop.
