A methodological approach for the selection of compatible and performable restoration mortars in seismic hazard areas

Abstract The application of restoration mortars in historic structures is the most usual conservation action. A methodology is herein established to extract compatibility and performance criteria utilizing the study of the historical structural materials of a monument and the results of fragility analysis. Thus, it is possible to evaluate restoration mortars’ compatibility and performance, through compliance with the set criteria and select the optimum material for earthquake resistant design of masonry structural systems in seismic hazard areas. The byzantine Catholicon of Kaisariani Monastery is utilized as a case study in order to illustrate the applicability of the methodology. The methodology can serve as a tool for decision making within a scientific framework.
