“…Aktan et al 141 focused on the concept and prospects of SHM and the network transmission and control, measurement checking and data management for bridges. Bergmeister 142 reported the monitoring and safety evaluation concept, structure and material, visual inspection and traditional field test, nondestructive detection, measurement method, system implementation and data acquisition, statistical analysis and assessment and monitoring examples for the concrete structure. The guideline by Rücker et al 143 demonstrated damage identification in the SHM.…”

Structural health monitoring (SHM) has been developed and applied to bridge structures since the early 1980s. Numerous approaches and techniques have been proposed and applied to supertall structures during the recent decade. This paper reviews the SHM techniques and applications in supertall structures. The vibration analysis techniques, seismic effect monitoring, wind effect monitoring, comfort assessment, temperature effect monitoring, and construction monitoring of high-rise structures are described and summarised. The latest developments in codification and standardisation in SHM are also introduced.

“…Beispiele finden sich z. B. in [1, 2]. Da sich die zu beurteilenden Baukonstruktionen oft in einem nicht zufriedenstellenden oder nicht hinreichend bekannten Zustand befinden und weil die einwirkenden Verkehrslasten fortwährend steigen, sollte auf weitreichende destruktive Eingriffe in die Bausubstanz verzichtet werden, um weitere Schädigungen zu vermeiden.…”

Durch die Einbeziehung von gemessenen Daten bei der Bewertung von bestehenden Bauwerken können Unsicherheiten bei der Beurteilung des Tragverhaltens reduziert werden, ohne das normative Zuverlässigkeitsniveau einzuschränken. Informationen sind die wesentliche Grundlage für die Analyse der Zuverlässigkeit von Tragwerken. Umso wichtiger ist die Kenntnis über die Präzision und die Richtigkeit der verwendeten Informationen. Aus messtechnischer Sicht kann ein Messwert, dem keine Messunsicherheit beigeordnet wurde, als wertlos erachtet werden. Liegt ein vollständig dokumentiertes Messergebnis vor, so ist die Qualität der gemessenen Information bekannt und deren Vergleichbarkeit gewährleistet. In diesem Beitrag wird am Beispiel einer Spannbetonbrücke und zweier Grenzzustände gezeigt, wie Messergebnisse aus der zerstörungsfreien Prüfung in probabilistische Nachweise von Bestandsbauwerken einfließen können und welche Auswirkungen die Implementierung von gemessenen Daten bei der Bewertung von Bestandsbauwerken haben kann.

“…The condition assessment of aging structures and infrastructures is becoming a more and more critical issue, especially when developing life extension and replacement strategies. A cost-effective maintenance strategy should aim for minimizing the total lifecycle cost of a structure, considering the costs for preventive maintenance, inspection, monitoring, repair, and failure losses (Bergmeister et al, 2003). The importance and the benefits were analyzed, by assessing the Value of Information (VoI) for structural health monitoring (SHM) systems, by Pozzi and Der Kiureghian (2011) and Kamariotis et al (2022).…”

Evolution, Recent Progress and Perspectives of the Seismic Monitoring of Building Structures in Romania

et al. 2022

The seismic instrumentation of structures in order to assess their condition and to track it over long periods or after representative events has proven to be a topic of large interest, under continuous development at international level. The seismic hazard of Romania poses one of the most dangerous threats for the country, in terms of potential physical and socio-economic losses. In recent years, taking advantage of the new scientific and technological advances, among which the exponential growth in computational resources, significant improvements have been made in extending the seismic networks for structural monitoring and using the data as input for products and services addressed not only to the research community but also to stakeholders. The paper covers focused aspects of the topic for Romania, referring to past developments of the most important institutions and seismic networks in the country and the current status, including the research and regulatory gaps. Currently, three main research and academic institutions perform structural health monitoring of twenty-two buildings in Romania. As the number of monitored buildings grows and new actors in the private sector start to get involved in the process, the need for data standardization and a regulatory framework increases. Ongoing national and international projects (PREVENT, SETTING, TURNkey) address these issues and outline the roadmap for future actions of the main institutions responsible for seismic risk reduction, including authorities, research and academia.
