Analysis and Design of a Base Isolation System for an Old Church with Masonry Structure

Lucian Soveja, Mihai Budescu

Abstract


The studies that consider the evaluation and the rehabilitation processes of historical masonry structures consist of structural analysis, aiming to better understand the seismic behaviour of these buildings, and also, may refer to the assessment of the safety level with respect to different rehabilitation strategies.


This paper present the case of an old historical masonry church for which a base isolation system has been developed. Aspects regarding the modelling process, finite element method analysis, modal and static linear analysis are presented. The efficiency of the base isolation system that has been designed for this specific structure is also verified using a time history analysis.
