Abstract

Retrofit indicates the application of new technologies to older systems. In construction industries, it refers to re-strengthening of the existing structure, which makes it earthquake resistant. It is a cost-effective approach to enhance the life span of an existing structure instead of redeveloping it. Before retrofitting an existing structure, it is essential to determine its present status. The structure may exhibit several deformities, right approach is imminent in treating distresses and strengthening the structure for future use. Non-destructive testing and analysis are one such approach taken before performing retrofitting on any structure. The tests comprise several parameters of the structure in terms of appearance, performance, durability and overall aesthetic appeal. This is done by testing for the hardness, quality, strength and durability of the structural members and materials used. In the present study, an existing building with visible signs of weathering was selected, on which non-destructive tests were conducted. The structural members that are lack in strength/durability were chosen for retrofitting. The method to retrofit was selected based on the type of distress encountered and member. RCC framed structure with basement was selected. The purpose of performing the non-destructive tests is to check the present condition        of building materials, viz., steel and concrete.
