A number of non-destructive tests NDT for concrete members are available to determine present strength and quality of concrete.
Structural audit should highlight and investigate all critical areas and recommend immediate remedial and preventive measures. The seismic evaluation of existing buildings compares their capacity against earthquake demand at specific site and concerns the potential earthquake-caused acu to building systems and elements that are closely related to human life safety.
ACI Committee 562
Structural audit is done by an experienced and licensed structural consultant. Enter the email address you signed up with and we’ll email you a reset link. Structural Audit of Buildings. It also helps in delivering a strong building structure with cost effective solutions and appropriate maintenance program.
Structural Audit of Buildings | Krishna Jaiswal –
To measure axi of reinforcement, diameter of reinforcement 3. It ensures that the building and its premises are safe and have no risk. It should cover the structural analysis of existing frame and find critical elements for all types of loadings.
If further use of such deteriorated structure is continued it may endanger the lives of the occupants and surrounding habitation. Structural Audit is an overall health and performance checkup of a building like a doctor examines a patient.
International Concrete Abstracts Portal
Appears on pages s: To measure strength, permeability, density of strength of concrete qualitatively, to determine structural integrity concrete. 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.
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.
Jaiswal auditing will help to implement maintenance and repair work timely which leads to prolonged life of the building and safety of the occupants. Introduction In India there are many old buildings which have reduced strength in due course of time. The International Concrete Abstracts Portal is an ACI aco collaboration with acu technical organizations from within the international concrete industry and offers the most comprehensive collection of published concrete abstracts.
These tests have been put under four categories depending on the purpose of test as under: The effective implementation of auditing enhances the life span of structure, prevents deterioration of building leading to sustainability.
The success of repairs and restoration is always based on thorough knowledge, correct diagnosis and 562-122 studies of problems 5662-12 building, proper repair practices and finally socio-economic considerations. Remember me on this computer. According to ACI R, to repair is to replace or correct deteriorated, damaged, or faulty materials, components, or elements of a structural system.
Conclusion The structural diagnosis is vast, important and highly responsible job which is connected with lives of human beings. Log In Sign Up. The purpose of strengthening is to increase the load-carrying capacity or stability of a structure with respect to its previous condition.
Appropriate actions should then be implemented to improve the performance of structures and restore the desired function of structures. Help Center Find new research papers in: 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.
It analyses and suggests appropriate repairs and retrofitting measures required for the buildings to perform better in its service life. 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.

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.
