Abstract : Earthquakes are very complex physical phenomena characterized by violent or chaotic movements of the Earth's crust.These movements are due to causes located in restricted areas within the Earth, located at distances higher or lower than the Earth surface, and have rapid variations in direction, velocity and acceleration. In fact, the Earth's rind suffers permanently from slight shocks, very small oscillations of the soil, which are imperceptible to humans, but which can be detected by recording devices (seismometers, accelerometers, etc.). These oscillations constitute micro-shaking of the earth's crust. Earthquakes are sudden and sometimes very strong movements, generally of short duration, which occur in layers from the earth's surface and give rise to oscillations that propagate in all directions within the earth and its surface to distances sometimes distant from the region where the initial movement occurred. Regarding the source that generates earthquakes, two possible production mechanisms are allowed: volcanic earthquakes due to volcanic eruptions, and tectonic earthquakes, due to important structural changes of the earth, accompanied by breaking or faltering phenomena. The most widespread (90% of all earthquakes), stronger and more important in terms of seismic engineering, are the tectonic earthquakes. Keywords - Ultimate Limit State, Service Limit State, Tubular Material, Double Stiffening Systems, Co-Operating Elements, Supports, Self-Supporting Spring, Arc, Double Arc Vierendeel.
