The primary objectives of this research thesis is to investigate the behaviour of reinforced concrete beams subjected to torsion, and more importantly the influences of FRP wrapping on these beams. The effects of wrapping these beams in different configurations also compiles to another objective of this thesis.
A controlled experimental procedure was planned, and all the related literature was reviewed. The literature consists of the various torsional models that are in use in these days for torsional design purposes.
The literature is summarised and followed by experimental procedures are then presented. This is then followed by the results and discussions, where the analysis of the results were in detail, with photos, graphs and tables.
Finally, a number of conclusions were made based on the experiments and the discussions. CFRP is found to be a great help in increasing the torsional capacity in reinforced concrete beams, depending on the methods of wrap. A few findings about the torsion model used were also stated.
