Retrofitting is the addition of new technology or features to older systems provides by Shrinik Steel Buildings. Retrofits can happen for a number of reasons, for example with big capital expenditures like naval vessels, military equipment or manufacturing plants, businesses or governments may retrofit in order to reduce the need to replace a system entirely. Retrofitting becomes necessary to enhance the performance of structures including those encountering loss of strength due to deterioration or which have crossed their expected life. The success of retrofitting depends on the actual cause and the measures adopted to prevent its further deterioration. The process involves repair, retrofit, renovation, and even part reconstruction.
Steel elements in the form of plates, channels, angles, and I-sections along with anchor bolts / through bolts could be used with proficiency for retrofitting of a damaged RCC building. The use of steel profiled sheeting has been demonstrated to replace or retrofit a damaged concrete roof. Steel sections and sheets being lighter their use does not add extra dead load on the existing structure but offers strength to the structural element as well as system. The detailing of the joints of Steel members with the cracked RCC members requires study of the nature of cracks, their extent and depth. Since it is very easy to give the steel members different shapes, it could be detailed in the most favourable way to fit into the system according to its necessity and available spaces. Some specific failures and its retrofitting measures are explained below.
