Abstract

The present study aims for the Earthquake creates great devastation in terms of life, money and failures of structures. Earthquake mitigation is an important field of study from a long time now. Seismic retrofitting is a collection mitigation techniques for earthquake engineering. It is utmost important for historic monuments, areas prone to severe earthquakes and tall or expensive structures. It is the modification of existing structures to make them more resistant to the seismic activity, ground motions and soil failure due to the earthquake. In the present time various structures made without any adequate detailing and reinforcement for seismic protection. Retrofitting is provided to improve the construction quality and bearing capacity for external load capability. This paper reviews the usefulness of using different retrofitting techniques such as bracing, jacketing, dampers, base isolation and shear wall used in the RCC Building to make it more stiffer. The retrofitting of building mainly results in the increase of stiffness, decreasing story drift and displacement. The review has been carried out on RCC buildings which first analyzed in ETAB’s software by static analysis and dynamic analysis and then retrofitted by using different retrofitting techniques. The best suited retrofitted technique is then used in field for retrofitting purpose in the RCC buildings which gives more stiffness, less story drift and less displacement on being analyzed in ETABS’s software.
