Remaining Life Assessment (RLA) Study and Retrofitting Old and Dilapidated Buildings
The building and the structures are basically considered for a particular design life and functionality to meet its purpose. However, due to various factors like design deficiency in the conceptual stage, poor quality of material and methodology in construction stage, lack of maintenance, exposure to aggressive environment, unexpected over loading, external impact, etc., the structures have reduced its strength in due course of time and sometimes causing mishaps endangering life of occupants, surrounding habitats including major financial losses. Periodical examination of health condition with proper diagnosis is thus very important step for ascertaining residual life of the building to enable to take corrective action for improvement of its strength and restoration process. Application of proper methodology by conducting semi-destructive/non-destructive tests with scientific instruments for investigation of structural members as per standard operation and codal provision to be carried out and the interpretation of results to be made to find out residual strength of various members of the building. The analysis will suggest appropriate measures to be undertaken for repair and retrofitting of the members so that the buildings and structures perform better and achieve the prolonged life of building. In this case, two industrial buildings, one from M/s J K Paper Mills, Rayagada, Odisha, and another from M/s Neelachal Ispat Nigam Limited (NINL), Jajpur, Odisha, have been selected as examples. The building selected from J K Paper Mills, Rayagada, Odisha, is an old RCC-framed structure of 24-m height, constructed almost 40 years back. After investigation, it was decided to abandon it and dismantle up to certain height for its safety and stability. In the second case, it is the Ammonium Sulphate Plant (ASP) building of Coke Oven and by-product plant of NINL which was constructed only 10 years back but having signs of distress such as spalling, disintegration and deterioration of concrete, exposure of corroded rebar, spillage of chemicals, dampness in RC members and in-filled walls, etc., because of sulphate and ammonia attack. After investigation, the affected members were identified and restoration measures were undertaken for structural deficient members. After restoration, the tests were re-conducted to check the improvement in the strength of members. This paper will be helpful to all the owner/occupier and engineers looking after the old and dilapidated buildings and industrial buildings having exposure to corrosive environment like steel, power and chemical plants, and housing societies requiring structural audit as per various regulatory and legal provisions of safety and stability.
