Abstract
Recently, the exclusive compulsory technical code (GB 50982-2014) for structural health monitoring of buildings and bridges in China has been developed and implemented. This code covers the majority of the field monitoring methods and stipulates the corresponding technical parameters for monitoring of high-rise structures, large-span spatial structures, bridges and base-isolated structures. This article first presents the comprehensive review and linear comparison of existing structural health monitoring codes and standards. Subsequently, the progress of the codification of GB 50982-2014 is imparted and its main features and specifications are summarized. Finally, in accordance with GB50982-2014, several representative structural health monitoring practical applications of large-scale infrastructures in China are exemplified to illustrate how this national code can bridge the gap between theory and practical applications of structural health monitoring. This technical code is an important milestone in the application of well-established structural health monitoring techniques into the realistic and complex engineering projects. Also, it can provide abundant and authoritative information for practitioners and researchers involving the structural health monitoring techniques.
Highlights
The rapid growth of large-scale civil infrastructures has undoubtedly driven and accelerated the development and application of structural health monitoring (SHM) in China
The main reason can be attributed to the lack of standardization of SHM principles and best practice guidelines (BPG)
For each type of structure, this code presents monitoring parameters, technical requirements of monitoring sensors and devices, optimal sensor arrangement and so on. This code puts emphasis on the structures that require monitoring during the construction and postconstruction stages, and SHM system is highly recommended to be installed on high-rise and towering structures, long-span spatial structures and bridges, as well as seismically isolated structures
Summary
The rapid growth of large-scale civil infrastructures has undoubtedly driven and accelerated the development and application of structural health monitoring (SHM) in China. In 2012, Germany issued an official guideline for the monitoring of bridges and other engineering structures.[18] The existing and comprehensive guidelines have witnessed the significant progress of SHM for large-scale infrastructures and presented a detailed and interim summary of the available SHM technologies and methods as well as the engineering application procedures. They will lay the foundation for the authoritative and abundant codes and standards of SHM, which can significantly promote the engineering applications of SHM. High-rise and towering structures, longspan structures Recommended In-service Monitoring parameters and measuring point arrangement method Periodic and longterm monitoring
