In India we come across many old buildings needing measures repairs or go earlier in to a state of dilapidation conditions to make them unfit for occupation. Regardless of improvements in construction materials and advance techniques, several concrete structure steel fails prematurely, leading to costly and time consuming repairs. More than 50% of Europe's and other developed countries annual budget is spent on repairs of deteriorated structures including rehabilitation and refurbishing of

... ing structures .in additions, it is well known that numerous existing concrete structures do not meet today's safety standards any more, in turn it become necessary to evaluate the service life of such structures against the today's unpredictable seismic activities so as to plan the repairs as total replacement of the structures which would not be economically feasible. Seismic evaluation of structures also plays an important role in buy/sale of properties, renting, insurance purposes, stability assessment of structures and deciding methodology for repairs. The seismic assessment of any structures requires obtaining first hand information regarding the current condition of the structure through condition survey. Such condition survey involves non-destructive and semi-destructive tests to obtain the strength and other properties of concrete and condition of reinforcement. Material properties and state of degradation can be known through assessment. Seismic evaluation of structures includes the scientific calculation of factors relating to strength, serviceability and durability by engineering methods.
