Torsional Strengthening of RC Beam using Ferrocement Jacketing
Abstract: Due to the type of loading on the structure, it is generally known that there are four structural actions: axial force, shear, bending, and torsion. The reinforced concrete beams are said to be subjected to torsion, when the point of application of lateral loads does not coincides with shear center of the beam. These loads may be due to loading pattern or connection of beam. Torsional failure is typically seen …
