ABSTRACT
The structural integrity and load distribution schemes in historical buildings are mostly based on the experience of the original building master, and much less or not at all on building mechanical analysis. The combination of historical experience with analytical understanding of force distribution in structures enables solutions to adapt historical constructions to actual codes and standards. This chapter deals with restoration projects, in which respectful structural engineering concept and design support the architectural and heritage values of the monument. Powerful methods are becoming available for the calculation of structural safety values. These methods need appropriate analysis models as input, reliable design models for strengthening of structural elements by means of externally bonded steel plates or fibre reinforced laminates, design models for the effect of grouting on strength and stiffness of ancient brick or block masonry, models for the design of timber strengthening.
