Abstract:
In civil engineering earthquake, the knowledge of the various parameters, for the design and the marking of any rational work is fundamental. The area of Constantine being located in a seismic area, the assumption of the
importance of the seismicity need a precise micro zoning.
The compilation of the historical seismic data of the area of Constantine, as those of the near areas avoisiantes will make it possible to determine the impact of the historical seismicity on the estimate of maximum acceleration on the ground which will be an important
value on the establishment of the spectra of response for the area of study. As the relations of attenuation can vary from a country with another and even from an
area with another, the local response spectrum can be an appreciable contribution for the seismic estimation of the effects on constructions. One proposes, starting from the historical seismicity and the parameters influencing
the acceleration of the ground to build spectra of response for the area of Constantine. These response spectrum will allow the ingineers in the field of construction and research to take account of some factors for the evaluation of the seismic risk. This work can be perceived only like one introduction to a research more sophisticated for the construction of the spectra of reliable answer, taking account in particular of the
influence of the wave propagation in the ground. This prospect will allow the establishment of relations of attenuation suitable for the area of Constantine.
