Retrofitting
From Swikipedia
Introduction
In general, retrofitting refers to the addition of new technology or features to older systems. In the context of buildings, retrofitting refers to the process of strengthening older buildings in order to make them earthquake resistant.
Retrofitting can also refer to the improving of existing buildings with energy efficiency equipment to reduce their consumption of fuels and concurrently reduce their carbon footprint. This kind of retrofitting is gaining popularity as the imminent impact of climate change is being felt.
Brief Description
Need for Retrofitting of Buildings
Nearly half the area of India falls in earthquake zones III, IV and V. Critical evaluation and need based strengthening of the buildings will be critical to reduce risk of their collapse. Pre-disaster preparedness strategies lead to retrofitting of the reinforced concrete structures for ensuring satisfactory performance during earthquakes. Retrofitting can lead to increased stiffness, strength, and failure-deformation.
Benefits of Retrofitting:
Strategy for prevention of buildings from damage due to earthquakes
Increased strength for buildings
Leads to improved energy efficiency if buildings are retrofitted with energy efficient building materials
Reduces the loss of life and property by protecting buildings
