Seismic Engineering


It is clear that the knowledge that earthquake engineers possess as well as the tools used in order to prevent earthquakes from taking place have considerably improved since the emergence of paraseismic engineering in the 1960s and 1970s. The improvements which have been made include:




– a better understanding of the causes and a better evaluation of powerful earthquakes due to the increase of recordings available of such powerful earthquakes, the increase in the number of study programs carried out on site as well as the development and advances made in digital simulation;

– a better understanding of seismic hazards for a particular site or for a particular region, i.e. the type and strength of seismic movements which are likely to occur in the future by taking into account the socio-economic importance and the life-span of existing and future buildings and constructions that may be affected by earthquakes;

– a better analysis of the behavior of structures which are subjected to strong tremors, thanks to the work carried out during post-seismic investigations, and thanks to the evolution and appearance of new trial methods (vibrating tables, reaction walls, centrifuges) as well as to the remarkable increase in computer processing capacity (particularly in the non-linear domain).

Have improvements as regards the knowledge of earthquake engineers and the improvements in study methods which are used to analyze earthquakes led to advances in relation to the prevention of earthquakes?
