The condition assessment of aged structures is becoming a more and more important issue for civil infrastructure management systems. The continued use of existing systems is, due to environmental, economical and socio-political assets, of great significance and is growing larger every year. Thus the extent of necessary repair of damaged reinforced concrete structures is of major concern in most countries today. Monitoring techniques may have a decisive input to limit expenditures for maintenance and repair of existing structures. Modern test and measurement methods as well as computational mechanics open the door for a wide variety of monitoring applications. The need for quantitative and qualitative knowledge has led to the development and improvement of surveillance techniques, which have already found successful application in other disciplines such as medicine, physics and chemistry. The design of experimental test and measurement systems is inherently an interdisciplinary activity. The specification of the instrumentation to measure the structural response will involve the skills of civil, electrical and computer engineers. The main aim of fib Commission 5, Structural servicer life aspects, is to provide a rational procedure to obtain an optimal technical-economic performance of concrete structures in service and to ensure a feedback of experience gained to design, execution, maintenance and rehabilitation. Against this background fib Task Group 5.1 Monitoring and Safety Evaluation of Existing Concrete Structures had been established to evaluate the existing practice worldwide. The objective of this state-of-art report is to summarize the most important inspection and measuring methods, to describe the working process and to evaluate the applicability to structural monitoring. Particular emphasis is placed upon non-destructive systems, lifetime monitoring, data evaluation and safety aspects.
Testing of Concrete in Structures, Third Edition
This book provides a comprehensive overview of the techniques involved in testing concrete in structures. The non-specialist civil engineer involved in assessment, repair or maintanance of concrete structures will find this a thorough update of the second edition, with an expansion of those areas where recent developments have made significant advances, for example in integrity assessment.
Testing of Concrete in Structures
Providing a comprehensive overview of the techniques involved in testing concrete in structures, Testing of Concrete in Structures discusses both established techniques and new methods, showing potential for future development, and documenting them with illustrative examples. Topics have been expanded where significant advances have taken place in the field, for example integrity assessment, sub-surface radar, corrosion assessment and localized dynamic response tests. This fourth edition also covers the new trends in equipment and procedures, such as the continuation of general moves to automate test methods and developments in digital technology and the growing importance of performance monitoring, and includes new and updated references to standards. The non-specialist civil engineer involved in assessment, repair or maintenance of concrete structures will find this a thorough update.
