28. 4. Concluding Remarks
4.1 Pisco earthquake produced a lot of of damage in non –
engineered buildings.However, many buildings had good
structural behaviour.
4.2 Seismic dissipation and isolation are recently applied
in Peruvian buildings to add damping. As a result, they
will improve their seismic response.
4.3 The Peruvian Seismic Code does not considere
anything about Energy Isolating and Dissipating
Devices.
