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.

1. 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;
2. Analyse the stresses in anchorage zones and design end anchorages for prestressed concrete beams and slabs;
3. Evaluate the short-term and long-term losses in prestressing and design prestressed structures considering these losses;
4. Discuss and appraise the recent advances in the prestressed concrete technology including the use of advanced materials and application of new technologies.
