Torsional strengthening of reinforced concrete beams using ...

May 15, 2017  Torsional strengthening using FRP has received less attention by researchers. Torsional strengthening, or upgrading the torsional capacity, of reinforced concrete (RC) beams may be necessary due to factors such as increased service loading, structural damage or deterioration, and more stringent updates in building codes.

Torsional Strengthening of Reinforced Concrete Beams Using ...

Aug 01, 2016  Few decades ago, there were no guidelines for torsion design of reinforced concrete (RC) beams. Hence, many existing beams in older buildings have a lack of adequate torsional strength since they were not properly designed for torsion. One way to regain/rehabilitate adequate torsional strength is through application of externally bonded carbon fiber reinforced polymers (CFRP).
