The purpose of strengthening is to increase the load-carrying capacity or stability of a structure with respect to its previous condition. It ensures that the building and its 52-12 are safe and have no risk.

In India, from onwards the infrastructure industry witnessed stepping up of public investment and growth in infrastructure industry which results in construction of new multistory concrete apartments which are now in the age of thirty plus years. To act more responsible and preemptive towards the dilapidated buildings, the municipal corporation must issue notices to the buildings and co-operative societies which are more than 30 years old to carry out mandatory structural audit and submit the audit report.
It also helps in delivering a strong building structure with cost effective solutions and appropriate maintenance program. The International Concrete Abstracts Portal is an ACI led collaboration with leading technical organizations from within the international concrete industry and offers the most comprehensive collection of published concrete abstracts.
More than ever, the construction industry is concerned with improving the social, economic and environmental parameters of sustainability.

To measure surface hardness of concrete 3. According to ACI R, to repair is to replace or correct deteriorated, damaged, or faulty materials, components, or elements of a structural system. Appears on pages s: There is demand of appropriate actions and measures for all such building structures to improve its performance and restore the desired functions of structures which may leads to increase its functional life.
It should cover the structural analysis of existing frame and find critical elements for all types of loadings.

The need of structural audit is for maintenance and repairs of existing structures whose life has exceeded the age of 30 years to avoid any mishaps and save valuable human life. To measure strength, permeability, density of strength of concrete qualitatively, to determine structural integrity concrete.
The effective implementation of auditing enhances the life span of structure, prevents deterioration of building leading to sustainability. Structural Audit of Buildings.

Abstract This paper deals to create awareness amongst the civil engineers, residents and owners of building towards the health examination of existing concrete buildings called as Structural Audit. Stages in Carrying Out Structural Audit 3. Remember me on this computer. The code is comprised of both prescriptive and performance requirements. The concrete is widely used as construction material being inexpensive, easy for construction, applications and because of it high strength-cost ratio.
Structural Audit is an overall health and performance checkup of a building like a doctor examines a patient. Structural audit should highlight and investigate all critical areas and recommend immediate remedial and preventive measures.
