With the passage of time, existing infrastructure which demands upgrading, retrofitting and/or repair is growing worldwide. Strengthening of structural elements such as beams, columns and slabs has become a mandatory step as on now, to reduce the amount of concrete waste generated by demolishing old construction in order to construct a new one. The strengthening of beams becomes difficult if it has to be strengthened to take revised loading due to many reasons. This paper aims at presenting both, traditional as well as advance strengthening techniques (specifically for beams) adopted actually on field. Concrete, steel and FRP composite are gaining importance as predominant materials for strengthening of existing RC beams on field [1]. Sometimes these materials are used in combination to achieve a good response and economy. Flexural, shear and axial strengthening can be done by the various techniques such as sprayed concrete, concrete jacketing, steel jacketing, near surface mounting technique, externally bonded FRP sheets or strips and many more. Researchers have been working extensively since years, adopting various techniques and materials for strengthening of existing reinforced concrete structures. The response of such strengthened structural elements is found to be quite satisfactory as compared to non-strengthened structural elements. This manuscript aims at presenting such mechanisms adopted for external strengthening of reinforced concrete structures.
