The concept of box behavior and the current performance-based approaches for seismic assessment specified in codes (e.g., EN 1998-1 2004 Sullivan et al. 2012) are explained here referring to cases of unreinforced and confined masonry building structures. In the next two sections, these typologies are presented in general terms. 

Rigid structures have short periods of vibration and are more susceptible to seismic destruction than flexible structures. For this reason, it is recommended that a seismic coefficient related to the vibration period of the tower be used in designing tall towers for earthquake loads. A tall, flexible structure capable of absorbing seismic shifts should not be penalized with the same seismic coefficient used for rigid structures such as masonry buildings that are more susceptible to failure from earthquakes.

In a historical masonry building, the efficiency of AE technique to monitor cracking is reported (Carpinteri Lacidogna 2006). Comparing crack traces and AE activity, it is shown that AE measurement can be used to dynamically measure structures in service.

Plastic composites are found to be effective in retrofitting masonry buildings to reduce seismic damage to remove seismic deficiency the thin layer of reinforcement (fibre reinforced composite sheet) applied to the wall (like wall paper) is shown to increase substantially the load carrying capacities of masonry walls [38] as well as of reinforced concrete structures, including columns and walls and beam-column joints [39]. 

An interesting example of the strengthening of masonry buildings is the structural adjustment of the Monastery of Santa Chiara in Naples, realized with the use of FRP fabrics in order to enhance the mechanical strength of masonry arches, as shown in Figs. 10.9 and 10.10.

This entry deals with the box behavior of masoiuy structures, which is a major hypothesis for the application of seismic assessment procedures based on the in-plane response of the walls, when using performance-based approaches for seismic safety. A general description is also made of the unreinforced and confined masonry building typologies, regarding the constructive technique, industrial development, and applicability. Methods and procedures are presented for the seismic assessment and safety verification of masOTiiy buildings, which are applied to the case of a dwelling.
