ABSTRACT
Seismic protection of buildings is a need-based concept aimed to improve the performance of any structure under future
earthquakes. Earthquakes of varying magnitude have occurred in the recent past in India, causing extensive damage to life
and property. Some recently developed materials and techniques can play vital role in structural repairs, seismic
strengthening and retrofitting of existing buildings, whether damaged or undamaged. The primary concern of a structural
engineer is to successfully restore the structures as quickly as possible. Selection of right materials, techniques and
procedures to be employed for the repair of a given structures have been a major challenges. Innovative techniques of the
structural repairs have many advantages over the conventional techniques. Some guidelines regarding selection of materials
for repair work such as steel, fiber reinforced polymer, has been discussed in the present paper. The selection of materials
and techniques to be used depend on many aspects that may be viewed from different prospectives i. e. requirement and
availability of financial resources, applicability and suitability of materials for the repair of damaged structures. Use of
standard and innovative repair materials, appropriate technology, workmanship, and quality control during implementation
are the key factors for successful repair, strengthening and restoration of damaged structures.
KEYWORDS: confinement, jacketing, fiber reinforced polymer jacketing, steel jacketing, beam jacketing.
