Structural rehabilitation is an important part of ensuring the safety and durability of a structure. It involves restoring a structure to its original position as closely as possible, and can be used to improve strength and durability, prolonging the life of the structure. With the increase in construction activities over the past two decades, many structures are already showing signs of distress, and repair measures may become necessary even within 5 to 10 years from completion. The success of the repair activity depends on the identification of the root cause of the deterioration of concrete structures.
All fiber types are available in various fiber forms and architectures, corresponding to the manufacturing processes, but also according to the requirements of FRP composites for structural rehabilitation. Before building any major project, the project owner should consult an engineer for structural analysis and safety. Restoration of the structure is an ultimate goal of repair and rehabilitation, where it plays an important role in maximizing the functional utility of the structure. The 26% rehabilitation retrofit concept has also been accepted as one of the important disciplines of the construction industry.
Repair and rehabilitation includes several systematic approaches that align with various strategies to promote a desired level in achieving the maximum life of the structure. In order to collect data for the design of structural rehabilitation, an extensive on-site research campaign is often carried out. This includes investigating hidden arches, removing plaster in some areas not visible in the hallway under the loggia; as a result, several arches hidden in the masonry can be detected. The authorities have included this methodology in their BOQs for other structures, and it is inspected regularly over the past two years26 on the basis of performance. Repair and rehabilitation is an art of civil engineering work that allows to extend the life of a structure, and it is essential for ensuring safety and durability.
