A Base Isolation Option for the Full Seismic Protection of an Existing Masonry School Building

Seismic Retrofitting of Historic Masonry Structures with the Use of Base Isolation—Modeling and Analysis Aspects

“…(Bailey and Allen, 1988;Pool and Clendon, 1992;Seki et al, 2000;Matsagar & Jangid, 2008;Mezzi et al, 2011;Aras & Atlay, 2015) and others, have demonstrated the effectiveness of the application of base isolation in terms of objectives of the conservation and re-use of buildings. In comparison with new buildings, the seismic base-isolation of existing buildings has some specific features.…”

“…Techniques have been developed which can be used to insert base isolation under buildings with some additional costs, which might be justified especially in the case of historic buildings with an extremely high or even inestimable value (Bailey and Allen, 1988;Pool and Clendon, 1992;Seki et al, 2000;Mezzi et al, 2011;Melkumyan et al, 2011;Melkumyan et al, 2014;Lignola et al, 2016). This paper deals with base isolation as a seismic restoration technique for masonry buildings belonging to the architectural heritage.…”

Aspectos económicos de un sistema de aislamiento sísmico de base para bastidores de acero en altura

“…where t p is the preparation or recovery time which expresses the community resilience to an earthquake event (35), t r is the repair time of the selected element (hours/piece) including fabrication and transport time of the steel profiles, and C rent is rent cost of a surface equivalent to that of the building (in EUR/hour) as suggested by (14). The recovery time (t p ) is the period necessary to restore the functionality of a structure, or an infrastructure system (water supply, electric power, hospital building, etc., or a community) to a desired level that can operate or function equally well, close to, or better than the original one (35).…”

“…Nowadays a seismic isolation can present an important alternative to conventional design method for the construction of low -to medium-(13) (14) and also high-rise (15) buildings in earthquake-prone areas. Currently, seismic isolation is mainly used in high seismicity regions in constructions of special importance or buildings containing extremely expensive equipment.…”

A Reconstruction Hypothesis of Collapsed Archaeological Masonry Barrel Vaults Employing Frictional Bearings, With Application to the Case Study of the Galleria Delle Volte Crollate, in Rome

“…Techniques have been developed that can be used to insert base isolation under existing buildings with some additional costs, which might be justified especially in the case of historic buildings with extremely high or even inestimable value (e.g. [7][8][9][10][11][12]). However, these retrofitting interventions, most of which realized abroad, end up being very invasive due to the necessity to create a rigid plane both at the intrados and at the extrados of the so-called isolation plane.…”
