MATERIALS AND JACKETING TECHNIQUE FOR RETROFITTING OF STRUCTURES Shri. Pravin B. Waghmare Address for Correspondence Acharya Shrimannarayan Polytechnic,Pipri(M), Wardha –Maharashtra 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.
