Construction system in seismic zones, with design of the fixed support with alternative function of mobile multidirectional support, with and without dissipation of sussultatory seismic energy

摘要

The proposed seismic zone construction system is essentially based on the following operations: 1. interruption of the continuity between the construction and the underlying foundation-ground complex, by making cuts at the top of the pillars, located between the construction and the foundation-ground complex; 2. insertion into the abovementioned cuts of fixed supports in the earth quiet state (absence of quakes) with the alternative function of mobile multidirectional supports in the earth movement state (quake present). In the event of seismic events, such a system permits the rigid translation of the foundation-ground complex with respect to the construction, which remains virtually still and undeformed under the prevalent action of the weight force. A variant to the abovementioned construction system is also proposed, compared with which it has the further property of spontaneous self-centring when the seismic event ceases. IMAGE
