A METHODOLOGY FOR THE ASSESSMENT OF HISTORICAL STRUCTURES BASED ON FINITE ELEMENT MODELS

This work proposes a methodology to analyze masonry historical structures (stone or brick). They are mainly characterized by their self-weight which is the dominant action that acts on them, such us churches, cathedrals, etc. The proposed methodology is based on the analysis of finite element models that simulate the real structure behaviour. Therefore, much more information can be obtained about the structure safety than applying the usual methodology (the graphical statics considering the limit analysis). Using the proposed methodology, the structure response can be determined applying some loads on the model and considering some support conditions that simulate foundation settlements. The effect of structural reinforcement, wear of some blocks, non linear properties of the materials, etc. can be also considered. The safety level of the studied structure is evaluated with the obtained analytical results.
