Design criteria and innovative techniques for seismic improvement: masonry tie beams and partition arches

The article (divided into three parts) presents several techniques for the seismic improvement of historic buildings, designed and tested in recent years by a research group from the University of Perugia.

The first part summarizes some of the major seismic issues of historic constructions and highlights the Reticolatus technique, developed by a spin-off of the University of Perugia.

In this second part, two additional techniques for the seismic improvement of historic structures are presented: reinforced masonry tie beams and reinforced partition arches.

The third part will discuss experiences related to the reinforcement of wooden beams using pultruded elements.
