Earthquake Protection of a Historical Building Through Base Isolation

摘要

Earthquakes present a potential great danger to historical buildings in seismic zones. The intervention strategy must be a process that requires teamwork of engineers, architects and authorities. The rehabilitation should be in accordance with the principles of the IABSE Symposium, Venice 1983 “Strengthening of Building Structures – Diagnosis and Therapy”. The paper presents the seismic isolation of a historical building using double-concave friction pendulum bearings. The building is listed in the historical monuments list, published in “Monitorul Oficial”, no. 670 bis from October 01, 2010, having the indicative PH-II-m-B-16310. The name is listed as ?Salonul de dans Dumitru Nicolae”. The intervention solution leads to a reduction of the internal forces in the structural elements of about 3.2 times on both directions of the building.
