Course Description:
The course aims to provide a deep understanding of the prestressing systems used in the civil engineering industry. The course will cover the basics of pre-tensioning and post-tensioning systems, load balancing, prestress losses, deflection of prestressed members, analysis for flexure, Magnel's approach to design for flexure, statically indeterminate analysis, design for shear, bond, and anchorage.
