The reduction of the effects of the dynamic action (earthquakes, wind, shocks and vibrations) on structures (buildings, equipment and pipe network) confronts difficult problems regarding their large size and weight as well as their high seismic acceleration or displacement. This paper proposes two alternatives to this critical problem. Solution 1 aims at a new seismic isolation system for buildings. The technological connections are achieved with special supports which allow a relatively high movement between the isolated and non-isolated buildings. Solution 2 aims at minimizing the dynamic structures response by relative deflection control and dissipation of a large amount of energy. The new solutions must be designed to be applied to new structures and to increase the degree of resistance to existing structures. The new devices, called ＂SERB-devices＂ can overtake large static loads over which dynamic loads may overlap and be damped. The devices allow ＂cutting-off＂ the dynamic action coming from the environment or generated from inside structures as well as the overtaking of shocks and vibrations generated by the systems to protect the environment.
