To assess depth of carbonation and pH of concrete 3. If further use of such deteriorated structure is continued it may endanger the lives of the occupants and surrounding habitation.
It also helps in delivering a strong building structure with cost effective solutions and appropriate maintenance program. The structural audit must be carried out following auditing norms, methods of non-destructive testing and code provisions.
Skip to main content. The seismic evaluation of existing buildings compares their capacity against earthquake demand at specific site and concerns the potential earthquake-caused risk to building systems and elements that are closely related to axi life safety. It analyses and suggests appropriate repairs and retrofitting measures required for the buildings to perform better in its service life.
ACI Committee 562
The purpose of strengthening is to increase the load-carrying capacity or stability of a structure with respect to its previous condition. The periodical structural auditing and diagnosis for health of existing buildings is thus utmost important for finding the present serviceability and structural viability of structures.
Appropriate actions should then be implemented to improve the performance of structures and restore the desired function of structures.
The effective implementation of auditing enhances the life span of structure, prevents deterioration of building leading to sustainability. Structural audit should highlight and investigate all critical areas and recommend immediate remedial and preventive measures.

Ac code provides the minimum requirements for the evaluation, repair, rehabilitation, and strengthening of existing concrete buildings and, where applicable, in nonbuilding structures. To measure strength, permeability, 562-122 of strength of concrete qualitatively, to determine structural integrity concrete.
Stages in Carrying Out Structural Audit 3. According to ACI R, to repair is to replace or correct deteriorated, damaged, or faulty materials, components, or elements of a structural system. To measure surface hardness of concrete 3.
Structural Audit of Buildings | Krishna Jaiswal –
This document was replaced by Some of these tests are very useful in assessment of damage to RCC structures subjected to corrosion, chemical attack, fire and due to other reasons. Jaiswal auditing will help to implement maintenance and repair work timely which leads to prolonged life of the building and safety of the occupants.
Help Center Find new research papers in: These tests have been put under four categories depending on the purpose of test as under: To measure cover of reinforcement, diameter of reinforcement 3. 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 done by an experienced and licensed structural consultant. 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.
The code and commentary is intended for use by individuals who are competent to evaluate the significance, limitations of its content and recommendations, and who will accept responsibility for the application of the material it contains.

International Journal of Civil Engineering Research. This paper deals with study of different parameter of structural audit including visual inspection, non-destructive testing, core sampling and testing. The success of repairs 562-2 restoration is always based on thorough knowledge, correct diagnosis and in-depth studies of problems in building, proper repair practices and finally socio-economic considerations.
Conclusion The structural diagnosis is vast, important and highly responsible job which is connected with lives of human beings. Structural Audit is an overall health and performance checkup of a building like a doctor examines a patient. The materials, processes, quality control measures, and inspections described in this document should be tested, monitored, or performed as applicable only by individuals holding the appropriate ACI Certifications or equivalent.
Strengthening of structural members can be achieved by replacing 5662-12 quality or defective material with better quality material, by attaching additional load-bearing material, such as high quality concrete, additional steel, thin steel plates, various types of fiber reinforced polymer sheets, and so on, and by the redistribution of the load such as by adding a steel supporting system.
