Analysing on a long term the effect of the gathered information it is evident that the scientists were recommending that the earthquake design spectra in the codes have to be increased. The consequences of this approach will be that the structures in the future will be more rigid, as well as heavier and during real strong ground motion will generate higher inertia forces and as a consequence of that we may expect again high level of vulnerability. Contrary to this approach is the structure to be designed as a flexible one and for controlling of deformations special devices to be added on the structure by which its dissipation capacity will be increased and deformations will be decreased. To demonstrate this concept of structural design a hypothetical five story steel frame structure is designed for ground acceleration of 0.2g and 0.4g based on EC 3 and EC 8 regulations. Analyses have been performed varying the viscous damping of the dampers from 10-30%, as well as increasing the peak ground motion up to 0.6 g. In this paper will be presented a set of data by which it will be demonstrated that by adding of devices at the floor levels more advanced and safer structure could be designed and the response of the structure exposed to time dependent loads could significantly be improved.
