Unit: CIVL6257: Concrete Structures - Prestressed Concrete (6 CP)
Mode: Normal-Day
On Offer: Yes
Level: Postgraduate
Faculty/School: Civil Engineering
Unit Coordinator/s: Mohotti, Damith
Session options: Semester 1
Versions for this Unit:
Campus: Camperdown/Darlington
Pre-Requisites: None.
Prohibitions: CIVL5257.
Brief Handbook Description: Objectives: To develop an advanced understanding of the behaviour, analysis and design of prestressed concrete structures.

Outcomes: Students will develop skills in the analysis and design of prestressed concrete beams, columns and slabs, to satisfy the serviceability and strength provisions of the Australian Concrete Structures Standard.

Syllabus Summary: The behaviour and design of prestressed concrete structures and structural elements, including beams and slabs. Topics covered will include steel and concrete materials, prestress losses, flexural and shear behaviour at service loads and ultimate loads, short and long term deflections, load balancing, anchorage zones (including strut and tie modelling of anchors), dynamic response of post-tensioned floors, and sustainability considerations for prestressed concrete structures.
Assumed Knowledge: None.
Lecturer/s: Mohotti, Damith
