“…-The embedding of the structures, the geometry and position of the building in the block (head, corner, middle) and the variations in gauge of one structure to another would not have the same frequencies (Douiri, A. and al., 2015), and damage and degradation of structures, soil-structure interaction. Age, and consequently the poor quality of materials and their fatigue (Jeston, A. R. and al., 2018), the rate of degradation of buildings during their life is also a major issue in frequency variations (Aldea, A. and al., 2018).…”

The response of ancient structures such as the Saint-Jean-Baptiste church or the current El-Badr mosque in Mostaganem (Algeria) to earthquakes depends on these physical characteristics and consequently on modal properties such as frequencies, damping and modal deformations. In this paper, ambient vibration tests were carried out on the three parts of the mosque building, and the response spectra and damping obtained will be correlated with the mechanical tests carried out in the second part of the work. Determination of the dynamic characteristics made it possible to distinguish differences in stiffness and to clearly highlight a disparity in frequencies in each structure, which may correspond to the age of each part of the building, the design and construction and differences in levels, etc. The results of the destructive tests give indications that confirm the hypotheses of ageing of the materials. The low young modulus of the various components partly confirms the frequency and damping values obtained. The experimental study of the mosque using ambient vibrations will give an order of magnitude of the vibratory mode periods, which are the first steps in any modelling, reinforcement and/or verification strategy and constitute a health record for this type of heritage.

“…Then, the structure's response to a large set of accelerograms simulated by the SIMQKE software (Gasparini and Vanmarcke, 1976) was computed and, for the final step, the fragility curves were constructed by comparing numerical interstory drift with the threshold criteria provided by the Hazus methodology (FEMA, 2003) for the slight damage state. Recent research on SHM, performed by UTCB, widened the scope of previous studies, approaching heritage buildings, such as the minaret of the Royal Mosque in Constanta (Aldea et al, 2018), and traditional Romanian timber framed masonry houses (Aldea et al, 2020).…”

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.
