Djillali BENOUAR is a founding member of the Algerian Academy of Sciences and Technologies (AAST) and is a Professor of Earthquake Engineering and Disaster Risk Management at the Faculty of Civil Engineering at the University of Science and Technology Houari Boumediene (USTHB) in Algeria and is Director of Research at the Built Environment Research laboratory (LBE) at USTHB. He has completed his PhD from Imperial College (University of London, UK) and his M.Sc. from Stanford University (CA, USA) and postdoctoral studies from University of Tokyo (Japan). He has published more than 50 papers in reputed journals and has been serving as an editorial board member for several scientific journals. He is a Science Committee member of the Integrated Research on Disaster Risk (IRDR), member of the Algerian Hazards Network (AHNet) and a partner of the Periperi U (Partners Enhancing Resilience to People Exposed to Risks), an African Consortium and an ICoE of the IRDR programme.

It details the measures taken at the country level as well as those involving the co-operation of international organizations. It discusses post-disaster measures including the relief of victims and the methodology of the assessment of the serviceability of damaged structures after the disaster, which represents one of the most important duty of the emergency staff, are also discussed. It examines the range of needed, possible and practical pre-disaster measures which the government of Algeria should undertake and actively encourage. This study briefly presents scientific and non-scientific Algerian organizations.

This is because many recent disasters had the biggest impact in urban areas with a large concentration of people heavily dependent on infrastructure and services. The rapid urbanization, population increase, development of critical engineering works, industrialization of cities with modern types of buildings, and the concentration of population living in hazardous areas are matter of growing concern, as they are likely to contribute to heavier loss of life and increasing economic losses in future disaster damage. The El-Asnam (formerly Orléansville) earthquake of October 10, 1980 (Ms 7.4) raised the awareness of both the Algerian government and the civil society of the need for disaster risk reduction policy. Since then, disaster risk reduction has been on the agenda of the government programs, and concrete measures have been undertaken in organization, legislation, institutions, training, education, communication, and information. The government has made significant efforts to improve the natural hazard governance. It has made a substantial impact on academic research and higher education in some disciplines of engineering and natural science in the country’s largest universities. Risk governance for natural hazard in Algeria will be seen here in light of the implementation mechanisms, the main achievements and progress, the new legal and regulatory tools and mechanisms, and cooperation aspects. In conclusion there will be a discussion about global evaluation and perspectives.

They are essential tools in earthquake engineering research since they simulate the effects of the true inertial forces on the test specimens. The destructive earthquakes that occurred at the north part of Algeria during the period of 1954-2003 resulted in an initiative from the Algerian authorities for the construction of a shaking simulator at the National Earthquake Engineering Research Center, CGS. The acceleration tracking performance and specifically the inability of the earthquake simulator to accurately replicate the input signal can be considered as the main challenge during shaking table test. The objective of this study is to validate the uni-axial sinusoidal performances curves and to assess the accuracy and fidelity in signal reproduction using the advanced adaptive control techniques incorporated into the MTS Digital controller and software of the CGS shaking table. A set of shake table tests using harmonic and earthquake acceleration records as reference/commanded signals were performed for four test configurations: bare table, 60 t rigid mass and two 20 t elastic specimens with natural frequencies of 5 Hz and 10 Hz.
