## Description

Structural forms, systems and load paths. Modelling and analysis of indeterminate structures. Energy methods and virtual work. Introduction to structural dynamics and the response of structures to earthquakes.

This course helps Civil Engineering students develop the important skill of visualising and computing the manner in which structures respond under the application of external loads. Students are introduced to the different types of commonly encountered structural systems, and the idealisation schemes typically employed to model them. A series of techniques are then developed to analyse structural models and compute the displacements and internal forces induced in them under the action of external static and dynamic loads. The analytical and numerical skills developed in this course are fundamental to the study of advanced Structural Engineering concepts in the 4th year and beyond. Furthermore, the concepts covered are also transferable to other engineering disciplines.

The course is split into two parts. The first half covers techniques to analyse the response of simple structures under time-varying dynamic loads. Methods are developed to compute the response of linear single degree of freedom systems under free vibration, periodic loads, pulse loads, and earthquake ground motion. The second part provides an overview of different structural systems and discusses techniques to visualise and compute their response to static loads. It specifically covers statically determinate and indeterminate analysis techniques, energy methods, the principle of virtual work, and the flexibility method of analysis

## Learning Outcomes

1.  Understand the force and displacement methods of analysis and apply them to analyse indeterminate structural systems; (Washington Accord WA1), (UC EIE3, EIE4)

2.  Understand the energy concepts and use them to analyse statically determinate and indeterminate structural systems; (Washington Accord WA1), (UC EIE3, BICC1)

3.  Understand the concept of moment redistribution and its application in analysing statically indeterminate structures (Washington Accord WA1), (UC EIE3, EIE4)

4.  Understand the fundamentals of structural dynamics and apply them to examine the behaviour of single-degree-of-freedom systems subject to simple and complex excitations;  (Washington Accord WA1), (UC EIE3, EIE4)

5.  Understand the applications of structural dynamics in earthquake-resistant structural design principles. (Washington Accord WA1, WA3), (UC EIE3,  GA2, BICC1)

## Assessment

Assessment Due Date Percentage  Description
Assignments 30%
final exam 35% Learning Objectives 5, 6, 7, 8
Mid Sem Test 35% Learning Objectives 1, 2, 3, 4

•  About 80% of your learning in this course will occur as you work on the assignments! Hence, you are strongly encouraged to start working on the assignments early and ask plenty of questions without fear of judgment.
•    You may work on the assignments in pairs and submit one solution for which both you and your partner will receive the same score. If you choose to work in pairs, it is expected that both you and your partner work together on all parts of all problems, and do not just divvy up the work among yourselves.
•    While you are permitted to discuss the problems with other students, you are not permitted to copy their work. The answers you submit should reflect your own organisation of the calculations and interpretation of the results. Please indicate on the first page of your solution, the names of the students outside your group whom you collaborated with. Failure to do so could be interpreted as academic dishonesty.
•    Since this is a professional engineering course, it is expected that your submitted solutions be neat and well organised. Marks will not be awarded for incoherent, untidy, or illegible submissions.
o Sketches and free body diagrams must be included where appropriate. They must be neatly drawn either digitally or using a pencil and ruler.
o Graphs must be plotted using a computer. They must contain axis labels, units, ticks, grid lines, and a legend where appropriate.
•    Assignment problems will be marked on a scale of 0 to 3 based on the following criteria:
o Completeness: Have reasonable attempts been made to solve all parts of the problem?
o Concept: Does the solution reflect an understanding of the underlying concepts?
o Execution: Have all the formulations and calculations been presented in a neat and orderly fashion?

The marking scale is defined as follows:

o 0 (Poor): No solution or less than 20% in completeness, concept, and execution
o 1 (Average): Between 20% and 50% in completeness, concept, and execution
o 2 (Good): Between 50% and 90% in completeness, concept, and execution
o 3 (Excellent): Above 90% in completeness, concept, and execution

All students enrolling in this course undertake that:

 they will conduct themselves with honour and integrity, both inside and outside the lecture theatres;
 they will exercise kindness, empathy, and compassion in their interactions with other students, tutors, faculty, and staff;
 they will not give or receive aid in the competency quiz and the final examination;
 they will not give or receive unpermitted aid in assignments, in the preparation of reports, or in any other work that is to be used by the instructor as the basis of grading;
 they will do their share and take an active part in seeing to it that others as well as themselves uphold the letter and spirit of the Honour Code.

Examples of conduct that may be regarded as being in violation of the Honour Code include:

 Representing the work of another as one’s own work
 Copying an assignment solution from another student or any other source
 Giving or receiving aid on an assignment under circumstances in which a reasonable person should have known that such aid was not permitted
 Copying from another student’s quiz or examination paper or allowing another student to copy from one’s own paper
 Giving or receiving unpermitted aid on a take-home examination
 Revising and resubmitting an assignment, quiz, or exam for regrading, without the instructor’s knowledge and consent
Sanctions for violating the Honour Code may range from a fail grade in the course to suspension from the university.

Special considerations

 The academic remedy for special consideration on the midterm test or the final exam will be an equivalent alternative assessment. These alternative assessments are only available to students who have approved special consideration applications for the assessments at an appropriate severity level.

 The mark on these alternative assessments will replace the original mark in the course grade calculation unless the student declines the offer or otherwise does not sit an alternative assessment, in which case the original mark will be used.
 The alternative assessments for this course will be held on-campus in the week of 8 July 2024. It is your responsibility to ensure that you are available for these dates if you want to benefit from the academic remedy for your special consideration.

 All communication associated with the arrangements of these equivalent alternative assessments will be conducted using official UC email accounts. The offer to sit an alternative assessment will come with a date/time during the resit week. Students will have a clearly specified amount of time to respond to the offer. Failure to respond will be interpreted as a declined offer.

 If a student has applied for special consideration but the application has not yet been approved when arrangements are being made for the alternative sitting, they may be permitted to sit the alternative assessment, but the mark will only be applied if the application is approved by the special consideration committee at an appropriate severity level.
