Development of Structural Health and Damage Assessment Chart of a Building

Abstract

As the requirement of infrastructure is increasing day by day, process of new construction is increasing rapidly but the quantity of old infrastructures is more, also new construction has some limitations, so the pre-constructed structures should be maintained properly to achieve their full life and also to reach economic balance. Building structures deteriorate with respect to time due to various environmental conditions like temperature, presence of moisture, humidity and gases, large seismic events affect overall durability and health of the building. Corrosion of reinforcement in the concrete is the main reason in concrete deterioration. This effect may further increase and severity of damage may increase. The need of the present study is to have a time saving and accurate methods to analyse the structural health of the infrastructure and also to suggest preventive measures to increase the service life of the structure. SHM also brings a quantitative metric that, when used properly, can compare current and healthy states to determine the extent of degradation and damage and, moreover, can be applied to predict the lifespan of structural systems.
