This course contains presentations about the design of reinforced and prestressed concrete elements for torsion. The focus is on practical design examples according to different concrete bridge and building codes. In addition to the design examples, presentations dealing with the current state-of-the-art on torsion in structural concrete, as well as recent advances in the analysis and design of concrete elements failing in torsion will be added.
The objective of this course is to provide practicing engineers with the tools necessary to better understand and design concrete elements for torsion. Usually, the attention that is paid to torsion in engineering education is limited to simplified textbook examples. The examples in this session will show applications in bridges and buildings, where the torsion design is combined with the design for flexure and shear. Finally, the theoretical presentations will give practicing engineers a deeper understanding and background on torsion in structural concrete.
