# STRUCTURAL ENGINEERING - 2018/9

Module code: ENG3176

Module Overview

The module provides an introduction to modelling structural behaviour used in practice in the design and analysis of structures. The Generalised Stiffness approach is introduced for skeletal forms and the Finite Element Method for continuous forms. Other relevant issues associated to modelling structures are introduced such as prestressing and instability of structures.

Module content

Generalised stiffness method – application of matrix methods to the modelling of plane trusses and unbraced frames;

Finite element method – an introduction to the method, including modelling principles, detailed consideration of 2D plane stress element and overview of membrane and shell element types. Introduction to the use of verification and validation processes in structural analysis modelling;

Plates – analysis of the bending of rectangular plates under the action of lateral loads – classical solution methods for stresses and deflections and the influence of boundary conditions. Applications to analysis and design of floor slabs and bridge deck slabs;

Plastic collapse – kinematic approaches to estimation of plastic collapse loads for beams, simple frames and simple slabs;

Stability – an overview of structural stability theory and its significance: buckling problems in columns, beam-columns and laterally unrestrained beams;

Prestressing – an overview of applications of prestressing in bridge and building structures and approaches of introducing prestressing in structural models.

None.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate knowledge and understanding of how to apply different analytical methods used to assess the performance of structural elements (i.e. frames, trusses, slabs and columns) through a 2 hour unseen written examination (LO assessed 1, 3, 4, 5, 6) and one coursework assignment (LO 1, 2, 3 and 6).

Thus, the summative assessment for this module consists of:

An unseen written examination [LO assessed 1, 3, 4, 5, 6] (2 hours, 80%)
Coursework assignment (20%) – [LOs assessed 1, 2, 3 and 6]

Coursework assignment (around 30 working hours) – 20%

-       Finite element method analysis - [1, 2, 3 and 6] (a, b, c and d)

Formative assessment and feedback is through a range of self assessment exercises provided on SurreyLearn. Worked examples will also be covered during tutorial sessions. Both type of excerises will provide automatic feedback where necessary. Feedback is also given on SurreyLearn in forum discussions and through comments on coursework submissions.

Module aims

• Introduce different analytical and numerical approaches to assess the performance of different structural elements (i.e. frames, trusses, slabs and columns) commonly found in structural engineering.
• Provide an appreciation of relevant topics in structural engineering such as prestressing and instability which can govern the design/analysis of structures.

Tutorial Hours: 11

Methods of Teaching / Learning

22 hours of lectures, 11 hours of tutorial classes, 30 hours of coursework and 87 hours independent learning.

2 hours examination.

Total student learning time 150 hours.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
