Condition Assessment of Structure Through Non Destructive Testing-A Case Study on Two Identical Buildings of Different Age

摘要

1 Introduction 1.1 Conditional Assessment Conditional assessment of any structure is must to check its suitability for the purpose which it serves. This is done of both old and new structures for new structure it is performed to check the quality of the work carried out by the contactor. The old buildings are assessed to know the remaining life [1] or to repair the structure. Mainly the old, weird, partially damaged, abandoned structure need conditional assessment to check weather that is it still serviceable and if so then for how long or if not then can it be retrofitted and made safe for the desired purpose. Also the conditional assessment is performed when the structure has to be expanded i.e. more number of floors are to be constructed on the existing old structure. Thus it becomes very important to assess the condition [2] of the structure. Concrete is mainly tested to assess the condition of a structure since it all depends on the properties of the concrete.
