ABSTRACT
This chapter discusses the results of the efficacy of a strengthening intervention on the Church "San Giovanni Battista" in Sottochiesa by tying the entire building through injected anchors equipped with a special fabric sleeve to guarantee effective and controlled grout injections. It describes the opportunity of testing and evaluating the possibility of making long diamond core drilling works along the perimeter walls in order to tie large buildings through injected anchors equipped with fabric sleeve. The analysis of the application of the technique of injected anchors placed into fabric sleeves to hoop the church allowed to assess the effectiveness of a retrofit intervention aimed at providing new continuity to the damaged walls and to contain the existing crack pattern. The Church presented a relevant crack pattern especially on the apse masonry dome. Future research will focus on evaluating contribution by means of analytical scheme and finite element analyses of the church under seismic conditions with and without the retrofit scheme.
