EARTHQUAKE ENGINEERING - 2019/0

Module code: ENGM054

Module Overview

Earthquake engineering module aims to cover the fundamental concepts associated with the way earthquakes are generated, principles behind seismic  hazard analysis, methods to analyse behaviour of structures and foundations under seismic loading, behaviour of ground during earthquakes (ground response analysis and liquefaction). It also covers earthquake resistant design principles.

Lecture Hours: 30

Semester 2

Prerequisites / Co-requisites

No prior knowledge of structural dynamics is assumed. Knowledge of 2nd order ordinary differential equations, matrix algebra and the theory of eigen-analysis is essential. In order to carry out the first course work, students should have basic knowledge of soil mechanics. For the second coursework, students should have a basic grasp of either a computing language or a spreadsheet program and able to use a structural analysis program.

Module content

•           Earthquakes: A geophysical and geological perspective

Basics of earthquakes, measurement of earthquakes, seismic hazard analysis, estimation of fault movements for design purposes.

•           Earthquake motion

Input motion characteristics and construction of synthetic/artificial input motion

Free and forced vibrations of SDOF systems, generalised SDOF systems, Rayleigh’s method, time domain numerical methods and Newmarks’s method, earthquake response spectra, behaviour of MDOF systems and modal analysis, Seismic design of structures according to EC8, member and connection behaviour.

Liquefaction and site response analysis, Advanced soil testing for dynamic design, use of Cyclic Triaxial and dynamic simple shear apparatus to study liquefaction, Liquefaction evaluation and mitigation techniques, Soil Structure Interaction issues in seismic design, design of foundations (shallow and deep foundations) in seismic areas, Winkler Spring approach for foundation design, detailed case studies of building and bridge failures during earthquakes.

Coursework, which combines both numerical and design aspects of earthquake engineering.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate

• knowledge and understanding of the basic principles of seismic design (LO’s 3, 5) is through a 2 hour unseen examination.

• solving open ended problem such as assessing the seismic hazards and evaluate the strategies for mitigation and re-engineering through acquired knowledge and understanding together with the necessary analytical skills to carry out design code specific calculations. This is done through course work (LO’s 1,2,3,4,5).

Thus, the summative assessment for this module consists of:

·         Examination [Learning outcomes assessed 3, 5] (2 hours) {60%}

·         2 pieces of course work [Learning outcomes assessed 1, 2,3,4,5] (40 hours) {40%}.

Coursework -1: Analysis of a pile-supported building (20 hours, 20%)

Coursework -2: Seismic analysis of a reinforced concrete building (20 hours, 20%)

Formative assessment and feedback

Formative assessment will be through a range of self assessment exercises and quizzes held in the class. These exercises will provide automatic feedback where necessary. Feedback will also be given in tutorial sessions.

Students will receive written feedback on their course work.

Module aims

• provide an appreciation of the causes of earthquakes and the hazards associated with it to the built environment.
• provide an understanding of the principles of seismic design and methods of analysis
• provide the ability to carry out calculations necessary for seismic design
• provide the ability to recognise the uncertainties in seismic analysis and design

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

• provide a specialist knowledge of structural and soil dynamics and earthquake engineering.

• deliver principally by lectures but also includes laboratory demonstration of advanced soil testing and learning through course work. The course work involves carrying out a structure and foundation design based on the fundamental principles and also by using software.

The learning and teaching methods include:

• Lectures (20 hours)

• Specialist seminars (4 hours)

• Laboratory classes and tutorials (6 hours)

• Course Work -1 including report writing (20 hours)

• Course Work -2 including report writing (20 hours)

• Exam (2 Hours)

Directed and guided reading (including revision ad preparation for lab classes) (78 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.
