Prestressed Concrete (4 ECTS)
This course concerns the fundamental aspects and points of interest in the design and detailing of prestressed concrete structures. A detailed overview of different techniques and their characteristics is presented, covering pre-tensioning, post-tensioning, partially prestressing, external prestressing and bonded and unbonded tendons. The equivalent prestressing load approach as a general procedure in the flexural analysis of statically determinate and statically indeterminate structures is introduced. The effects of shrinkage, creep and relaxation on loss of prestressing and redistribution of forces are discussed. Special attention is given to the crack width control in partially prestressed members and the bending moment and shear resistance in general. Strut and tie models are used for shear resistance and to introduce forces in disturbed regions. Detailing of prestressed structures is discussed.
