Abstract
To improve the performance of any structure under seismic condition and future earthquake is very
essential now-a-days because earthquakes have occurred in the recent past in India varying magnitude. So, it is quite
important to develop some innovative techniques, materials and solution for the structural repair, seismic strengthen
and retrofitting of existing buildings. Selection of right materials and right technology is a challenging task for the
structural engineers over some conventional method.
Jacketing is the most popularly used method for strengthen the building columns. The most common types of jackets
are steel jacket, reinforced concrete jacket, fiber reinforced polymer composite jacket, jacket with high tension
materials like carbon fiber etc. In this paper, To compare the axial load carrying capacity of retrofitted square
columns with reference square column of size (240mmx240mmx720mm), hence to determine the suitability of RC
jacketing technique for this. Use of standard and innovative repair materials, appropriate technology, workmanship
and quality control during implementation are the key factors for successfully repair, strengthen and restoration of
damaged structures.
