Appears on pages s: It is mandatory and advisable to carry out the periodical structural audit of the buildings by professional experts and act immediately through recommendations provided in audit report.

The success of repairs and 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. Remember me on this computer. To measure strength, permeability, density of strength of concrete qualitatively, to determine structural integrity concrete.

Structural audit should highlight and investigate all critical areas and recommend immediate remedial and preventive measures. In this method cylindrical core samples are taken from existing structures.

ACI Committee 562

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.

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 assess depth of carbonation and pH of concrete 3. The structural audit must be carried out following auditing norms, methods of non-destructive testing and code provisions. The acu of strengthening is to increase the load-carrying capacity 5562-12 stability of a structure with respect to its previous condition.

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. The cores are visually inspected and tested in laboratory to check its compressive strength. Help Center Find new research papers acl More ai ever, the construction industry is concerned with improving the social, economic and environmental parameters of sustainability.

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 human life safety. A newer version of this document exists. Jaiswal auditing will help to implement maintenance and repair work timely which leads to prolonged life of the building and safety of the occupants.

Appropriate actions should then be implemented to improve the performance of structures and restore the desired function of structures. International Concrete Abstracts Portal. Conclusion The structural diagnosis is vast, important and highly responsible job which is connected with lives of human beings. 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.

It also helps in delivering a strong building structure with cost effective solutions and appropriate maintenance program.

The concrete is widely used as construction material being inexpensive, easy for construction, applications and because of it high strength-cost ratio. 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.

Structural Audit is an overall health and performance checkup of a building like a doctor examines a patient.

From this point of view, repair may be divided into structural qci and serviceability repair. Structural Audit of Buildings. These tests have been put under four categories depending on the purpose of test as under: 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.

This paper deals with study of different parameter of structural audit including visual inspection, non-destructive testing, core sampling and testing. To measure cover of reinforcement, diameter of reinforcement 3. Strengthening of structural members can be achieved by replacing poor 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.

The code is comprised of both prescriptive and performance requirements. Log In Sign Up. There are many buildings during this period and earlier have reduced strength in due course of time because of structural deficiency, material deterioration, unexpected over loadings or physical damage.
