Various methods for retrofitting prestressed concrete members: A critical review

Abstract

Structures of a building can get exposed to adverse conditions resulting from overloading situations, which would eventually contribute to massive building degradation. The choice to repair the building structures seems to be very costly. The possible step that could be taken is by implementing a method of reinforcing and strengthening the building structures. For the past years, strengthening methods by implementing various innovative technologies has been seen to become a modern scientific topic in the fields of environmental and civil engineering study. Previous related studies on the reinforcement of pre-stressed concrete beams (PSC) by adding different elements have been observed by past researchers. The tests were carried out to evaluate the shear and flexural capacities of the building structures after the mechanisms were installed. A large number of scholars have conducted such studies with different types of interacting factors. In this study, a review will be presented by analyzing various techniques that have been implemented by multiple researchers for strengthening pre-stressed concrete beams, as well as their shear and flexure performances of the beams.
