Your lecturer

Dr Weena Lokuge graduated from University of Peradeniya, Sri

Lanka in 1994 with BSc in Civil Engineering, Asian Institute of

Technology, Thailand in 1997 with MEng in Infrastructure

Planning and Management and Monash University, Melbourne

in 2004 with PhD in Structural Engineering. During her 10

years academic experience, she worked as a Teaching Assistant

at University of Peradeniya, Sri lanka, Lecturer at University of

Ruhuna, Sri Lanka, Research Associate at Asian Institute of

Technology, Thailand and Research Associate at RMIT,

Melbourne. She has industry experience as a structural engineer

in multi storey buildings and water retaining structures.

She joined USQ in February 2010 and currently working as a

Lecturer in Civil Engineering. Her research areas include

composite materials, rehabilitation of concrete structures and

infrastructure management. She is a member of the Institute of

Engineers, Australia.

The work done by the previous examiner, Prof Thiru Aravinthan in developing the teaching materials for this course is greatly appreciated.

In this course, electronic discussion facilities will be used extensively for communication

between your lecturer and fellow students.

Online quizzes are summative assessment items to check your understanding of each module.

You should attempt these quizzes to enhance your learning of this course and get some marks

as part of your assessment.

There will be discussion topics posted from time to time through out the course. You are

expected to participate in this discussion and share your views. You can make use of this

discussion area to post your queries on the modules.

USQAdmin

USQAdmin, also accessed through UConnect, allows you to access a number of administrative

functions such as changing your contact details, checking your enrolment details, accessing

Course home page in USQStudyDesk

To access course home page, go to USQ Study Desk Select CIV8802, which should take you to the course home page.


Attempting Quizzes

You will find the quizzes in some of the topics in the study desk (some of these quizzes will

appear later on as you progress in your study).

To attempt a quiz, you need to click on the relevant icon for the quiz. You are allowed a

maximum of 2 attempts. Most questions are of multiple-choice type with a few questions of

other types such as filling the blanks etc. Once you have selected the right answer for each

quiz, click on Save Answer. When you have completed click on Finish to submit your work. You will get the scores and correct answers including some feedback immediately. You can

also review your assessment scores later on for each attempt by clicking on the Assessment icon on the top tool bar and navigating your way to the relevant quiz.

Many students (both external and on-campus) students have found these quizzes to be a very

useful self-assessment tool to check your understanding of the basic concepts in this course. I

hope you will make the best use of it!

Pre-requisite course

It is expected that you have completed a course in the design of reinforced concrete structures

at an undergraduate level. Prestressed concrete is in a way, an extension of the design of

reinforced concrete structures; hence you need to be familiar with the basic design of reinforced

concrete structures.

Assessment

Assessment in this course is by way of three assignments totalling 100%. As per the course

specification, you are required to achieve least 50% overall in the three assessments in order

to eligible for a pass in the course.

Discussions/Quizzes (25% worth) will consist the following, which will be ongoing

throughout the semester:

1. Attempting online quizzes (15%)

2. Participation in discussions topics (10%)

Assignment 1 (25% worth) will consist of a minor design task to check understanding of

basic design concepts (25%)

Assignment 2 (50% worth) will represent a detailed design of a prestressed concrete

deck/beam structure.

Studying for and completing these assignments will represent a significant part of your total

workload in this course. They have been designed to focus you on the particular material which

is of key importance within the course.


Important advice

The text references are important to get a good grasp of the basic concepts of prestressed

concrete. Your first objective should be to get an understanding of the methods of prestressing

and of the qualitative behaviour of prestressed beams. Next you need to appreciate that in

prestressed concrete, the design requirements are more complex than with other types of

members. In particular it is necessary to check stresses not just at the final limit state loading

condition but also at different stages during construction. Also you need to appreciate that in

designing a prestressed beam it is necessary not only to determine the necessary number of

prestressing strands but also the jacking force that must be applied to these strands.

The latter modules will cover miscellaneous topics including recent advancement in prestressed

concrete. These topics include the design and construction of externally post-tensioned bridges

and grouting issues in bonded tendons that is being the current topic of discussion in the

prestressed industry.

Course evaluation

Feedback from students studying USQ courses is very valuable to the university. There will be

information available in the study desk on how to access student evaluation. This link can be

found under the Useful Links at the top of the study desk page.
