International Journal of Civil Engineering Research. 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. Introduction In India there are many old buildings which have reduced strength in due course of time. Appears on pages s: Skip to main content.
Structural Audit is an overall health and performance checkup of a building like a doctor examines a patient. This code provides the minimum requirements for the evaluation, repair, rehabilitation, and strengthening of existing concrete buildings and, where applicable, in nonbuilding structures.
Enter the email address you signed up with and we’ll email you a reset link. It also emphasizes on different repairs and retrofitting measures to be used for buildings after structural audit.
The cores are visually inspected and tested in laboratory to check its compressive strength. The materials, processes, quality control measures, and inspections described in this document should be tested, monitored, 562-21 performed as applicable only by individuals holding the appropriate ACI Certifications or equivalent.
This paper deals with study of different parameter of structural audit including visual inspection, non-destructive testing, core sampling and testing.
From this point of view, repair may be divided into structural repair and serviceability repair. Help Center Find new research papers in: Post Structural Audit 4.

In this method cylindrical core samples are taken from existing structures. International Concrete Abstracts Portal. Click here to sign up. The code is comprised of both prescriptive and ai requirements. This document was replaced by Stages in Carrying Out Structural Audit 3. Structural audit should highlight and investigate all critical areas and recommend immediate remedial and preventive measures.
ACI Committee 562
It analyses and suggests appropriate repairs and retrofitting measures required for the buildings to perform better in its service life.
Wci newer version of this document exists. Appropriate actions should then be implemented to improve the performance of structures and restore the desired function of structures. Commentary is provided for both the prescriptive and performance requirements and is intended to provide guidance to the licensed design professional and referenced sources for additional information the material presented in the code provisions.

More than ever, the construction industry is concerned with improving the social, economic and environmental parameters of sustainability. It should cover the structural analysis of existing frame and find critical elements for all types of loadings. Log In Sign Up.
It also helps in delivering a strong building structure with cost effective solutions and appropriate maintenance program. Conclusion The structural diagnosis is vast, important and highly responsible job which is connected with lives of human beings. According to ACI R, to repair is to replace or correct deteriorated, damaged, or faulty materials, components, or elements of a structural system.
Structural Audit of Buildings. 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. Jaiswal auditing will help to implement maintenance and repair work timely which leads to prolonged life of the building and safety of the occupants. If further use of such deteriorated structure is continued it may endanger the lives of the occupants and surrounding habitation.
To assess depth of carbonation and pH of concrete 3. The former refers to the restoration of lost sectional or monolithic properties of damaged members, while the later refers to the restoration of structural surfaces to a satisfactory operational standard.
To measure cover of reinforcement, diameter of reinforcement 3.
If, further use of such deteriorated structure is continued it may endanger the lives of occupants and surrounding habitation. 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.
To act more responsible and preemptive towards the dilapidated buildings, aco 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.
Remember me on this computer. 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.
In India, from onwards the infrastructure industry acii stepping up of public investment and growth in infrastructure industry which results in construction acj new multistory concrete apartments which are now in the age of thirty plus years.
