Analysis of Retrofitting Residential Building by E-Tab

the retrofitting of concrete structures has become increasingly important in view aging and more deterioration of infrastructure. The problem is more severe due to optimized technologies for construction. Many expansive methods are available for retrofitting structures and choice of suitable method/material is a challenge to a structural engineer. Retrofitting is the Science and Technology of strengthening the existing structures or structural elements to enhance their performance with new technology, features and components. Retrofitting of an existing reinforced concrete structure includes either repair, rehabilitation (or) strengthening terms. The term retrofit is used if the damaged structure performance was satisfying than before with some additional resistance then the term retrofit will be representative. The different retrofitting methods such as steel and concrete jacketing and application of fiber reinforced polymer (FRP) composites which were used to improve the load bearing capacity of individual structure elements are highlighted and methods such as shear walls and shear cores which can be used to improve overall stability of buildings. Most retrofitting techniques will result an increase in stiffness and slightly increase in mass. Thereby redesigning and retrofitting by column jacketing were taken to modify the structure to withstand increased load..
