Cambios en los períodos fundamentales de edificaciones construidas con el gran panel soviético

After a visual inspection of 200 buildings built with the prefabricated great soviet panel system in Santiago the Cuba, factors leading to potential seismic damage were detected. These factors include pathological damage to structural elements and joints, with severe levels of damage. Likewise, chan...
