Completion of undergraduate course CIV3506 Concrete Structures or equivalent. Familiarity with design standards for structural engineering.
This course provides students with an opportunity to enhance their skills in prestressed concrete design and applications.
Prestressed concrete is used extensively in bridges, multistorey buildings and many other important parts of today's modern infrastructure. The inherent weakness of concrete in tension is offset by introducing a pre-compression in a prestressed member, which improves its service load behaviour, such as reduced deflections and cracking. An advanced understanding of its behaviour is essential before safe and economical designs can be produced. This course will provide a detailed coverage of: The behaviour of prestressed concrete, analysis and design for strength and serviceability of prestressed concrete members, such as beams and slabs including continuous members, and anchorage design and losses in prestress. It will also cover the recent advances in prestressed technology including external post-tensioning, use of fibre reinforced plastics in prestressing and improvement in the durability of prestressed concrete structures.
The course objectives define the student learning outcomes for a course. On completion of the course, students should be able to:
- evaluate the behaviour and design of prestressed concrete beams and slabs (including statically indeterminate beams and slabs) and design tendon layout, which satisfy the strength and serviceability limit states as required by design standards;
- analyse the stresses in anchorage zones and design end anchorages for prestressed concrete beams and slabs;
- evaluate the short-term and long-term losses in prestressing and design prestressed structures considering these losses;
- discuss and appraise the recent advances in the prestressed concrete technology including the use of advanced materials and application of new technologies.

Important assessment information
There are no attendance requirements for this course. However, it is the students' responsibility to study all material provided to them or required to be accessed by them to maximise their chance of meeting the objectives of the course and to be informed of course-related activities and administration. (ii) Students must participate in discussions posted on the USQStudy Desk.
Requirements for students to complete each assessment item satisfactorily:
To satisfactorily complete an assessment item a student must achieve at least 50% of the marks or a grade of at least C-. Refer to Statement 4 below for the requirements to receive a passing grade in this course.
Penalties for late submission of required work:
If students submit assignments after the due date without (prior) approval of the examiner then a penalty of 5% of the total marks gained by the student for the assignmnent may apply for each working day late up to ten working days at which time a mark of zero may be recorded. No assignments will be accepted after model answers have been posted.
Requirements for student to be awarded a passing grade in the course:
To be assured of receiving a passing grade in a course a student must obtain at least 50% of the total weighted marks for the course.
Method used to combine assessment results to attain final grade:
The final grades for students will be assigned on the basis of the weighted aggregate of the marks (or grades) obtained for each of the summative assessment items in the course.
There is no examination in this course.
Examination period when Deferred/Supplementary examinations will be held:
University Student Policies:
Students should read the USQ policies: Definitions, Assessment and Student Academic Misconduct to avoid actions which might contravene University policies and practices. These policies can be found at http://policy.usq.edu.au.
The due date for an assignment is the date by which a student must despatch the assignment to USQ. The onus is on the student to provide proof of the despatch date, if requested by the Examiner.
Students must retain a copy of each item submitted for assessment. This must be despatched to USQ within 24 hours if required by the Examiner.
In accordance with University's Assessment Policy (Regulation 3.3.2), the examiner of a course may grant an extension of the due date of an assignment in extenuating circumstances.
The usual method of assessment submission for the Faculty is by written, typed or printed paper-based media (i) submitted to the Faculty Office for students enrolled in the course in the on-campus mode, or (ii) mailed to the USQ for students enrolled in the course in the external mode. The due date for the assessment is the date by which a student must (i) submit the assessment for students enrolled in the on-campus mode, or (ii) mail the assessment for students enrolled in the external mode.
The Faculty will NOT normally accept submission of assessments by facsimile or email.
If electronic submission of assessments is specified for the course, students will be notified of this in the course Introductory Book and on the USQ Study Desk. All required electronic submission must be made through the Assignment Drop Box located on the USQ Study Desk for the course, unless directed otherwise by the examiner of the course. The due date for an electronically submitted assessment is the date by which a student must electronically submit the assignment. The assignment files must be submitted by 11.59pm on the due date using USQ time (as displayed on the clock on the course home page; that is, Australian Eastern Standard Time).
Students who do not have regular access to postal services for the submission of paper-based assessments, or regular access to Internet services for electronic submission, or are otherwise disadvantaged by these regulations may be given special consideration. They should contact the examiner of the course to negotiate such special arrangements prior to the submission date.
Students who have undertaken all of the required assessments in a course but who have failed to meet some of the specified objectives of a course within the normally prescribed time may be awarded the temporary grade: IM (Incomplete - Make up). An IM grade will only be awarded when, in the opinion of the examiner, a student will be able to achieve the remaining objectives of the course after a period of non-directed personal study.
Students who, for medical, family/personal, or employment-related reasons, are unable to complete an assignment or to sit for an examination at the scheduled time may apply to defer an assessment in a course. Such a request must be accompanied by appropriate supporting documentation. One of the following temporary grades may be awarded IDS (Incomplete - Deferred Examination; IDM (Incomplete Deferred Make-up); IDB (Incomplete - Both Deferred Examination and Deferred Make-up).
Harvard (AGPS) is the referencing system required in this course. Students should use Harvard (AGPS) style in their assignments to format details of the information sources they have cited in their work. The Harvard (AGPS) style to be used is defined by the USQ Library's referencing guide. http://www.usq.edu.au/library/referencing.
Students must have access to e-mail and internet access to UConnect for this course.
