A seismic assessment method conceived for historical buildings, and especially focused on older churches, is presented. The relevant evaluation analysis is articulated on a series of performance levels formulated to this aim, and developed by linear finite element models, or models with localised non-linearities. The application to a demonstrative case study, represented by a fourteenth-century church, highlights unsatisfactory response capacities of this building with respect to the proposed criteria. A base-isolation seismic retrofit hypothesis, previously elaborated without precise performance objectives, is then re-examined for this church so as to reach the assumed levels.

Abstract

A seismic assessment method conceived for historical buildings, and especially focused on older churches, is presented. The relevant evaluation analysis is articulated on a series of performance levels formulated to this aim, and developed by linear finite element models, or models with localised non-linearities. The application to a demonstrative case study, represented by a fourteenth-century church, highlights unsatisfactory response capacities of this building with respect to the proposed criteria. A base-isolation seismic retrofit hypothesis, previously elaborated without precise performance objectives, is then re-examined for this church so as to reach the assumed levels. The silicone fluid-viscous devices included in this intervention hypothesis are dimensioned by a general design procedure, recently proposed within the same research project.
