Abstract

Retrofitting is referred to as modifying existing equipment or structure with additional or new components or members. To make older structures more resistant to accidents or seismic activity, retrofitting is referred to as modifying existing equipment or structures with new or additional members or components. An existing structure is less susceptible to damage when it is retrofitted. The use of retrofitting is on the rise right now. The structures' strength, resistivity, and overall lifespan can all be improved through retrofitting. Its sole objective is to reinforce the structure once more. because structures lose strength over time. The most common way of adding new elements to more established and vulnerable structures is known as retrofitting. The most cost-effective way to make an insecure building safe from future dangers like earthquakes is through retrofitting. It was discovered that retrofitting also aids in restoring the structure's strength after it was damaged by fire or accident. By wrapping fiber-reinforced polymer (FRP) sheets in layers of four or more, the standard concrete structure quickly gained strength. By adding more FRP wrappings, the strength can be made even stronger.
