The constructions submitted to this type of earthquakes must be capable of supporting big deformation and dissipate important quantity of energy in few cycles and short time. To mitigate the destructive effects of the earthquakes in general, there have been developed in the last decades devices of dissipation of energy and seismic isolation. Contradictory opinions exist with regard to the efficiency of this type of devices for to earthquakes near-fault. The objective of the work is to evaluate numerically the response of two types of devices of seismic protection subject to earthquakes of near-fault. The distinctive characteristics of the earthquakes of near-fault describe a suitable set of records which are to selected to the analysis of numerical models. Buckling restrained braces are selected as devices of dissipation of energy, as well as system of hybrid isolation composed by spiral springs of steel and visco elastic dampers. Non linear dynamic analysis of simple models is carried on with the devices of seismic protection. The results show that there is not a single ground motion parameter to characterize the responses of the two structure with protection devices studied. A great variability of selected response parameters is observed.
