Abstract:The retrofitting of existing masonry buildings is now a crucial problem for Europe. Indeed, structural safety and energy efficiency should represent the target of any renovation. The proposal of a new synthetic performance parameter is presented and discussed. Following this approach, in this paper, after a review of the main studies available in the literature, a proposal of a new performance parameter approach is presented and discussed. It is capable of taking into account both the structural and thermal aspects of masonry retrofitting. An emblematic set of reinforcements and energy improvements for masonry walls is examined. An example, generalized formulas, and a simultaneous evaluation of the role of multiple structural and thermal parameters on masonry buildings are proposed, with a view to optimize several categories of costs related to the intervention.

“…The study determines that CFRP stripe materials prove to be a good alternative for strengthening the structural brick walls against the lateral loads in that energy dissipation capacities are improved. Albert et al [2] conducted experimental works to determine the behaviour of the structural brick walls strengthened using carbon and glass FRPs under cyclic axial compressive loading, with various FRP forms, quantities and number of layers. Also providing the analyses on out-of-plane lateral loading, the study establishes that the performance of pre-damaged and non-damaged brick wall specimens strengthened using carbon fi bre stripes are much better than those strengthened using glass fi bres.…”

It is crucial for masonry structures of historical value to increase their seismic performances in order to be protected against earthquakes. The damages to the masonry structures might be attributed to insuffi cient soil properties, non-conformity with relevant regulations, design and application defects and wear. This study experimentally investigates the strengthening of the masonry structures on one side as historical structural walls can only be strengthened on one side in most cases. In the experimental works conducted within the scope of the study, the brick wall specimens, some of which are pre-damaged, are strengthened on one side using carbon fi bre reinforced polymers (CFRPs) in different forms. Comparisons are made between the change in the load-bearing capacities and behaviours of the specimens following the strengthening. It is determined that the brick wall specimens without reinforcement exhibit brittle behaviour, whereas the performances of the brick wall specimens strengthened with CFRP improve in strength ratings as well as energy dissipation capacities. The improvements in the specimens of the structural brick walls become much more outstanding when the strengthening is applied on the overall surface of the wall in textile form rather than in strip form.

“…The structural vulnerability and damage-failure patterns of unreinforced masonry (URM) were studied by many researchers (Korkmaz, 2010;Bruneau, 1994;Tornabvie, 1997;Benedetti et al, 1998;Abrams, 2001;Paquette and Bruneau, 2003;Doherty et al, 2002). Of the methods considered, injection grouting, insertation of reinforcing steel, prestressing, jacketing, use of FRP and various surface treatments were the most common (Albert et al, 2001). The difficulties in performing advanced testing of this type of structures are quite large due to the innumerable variations of masonry, the large scatter of in situ material properties and the impossibility of reproducing it all in a specimen (Zucchini and Lourenco, 2004).…”

Abstract. Turkey and neighborhood countries like Greece and Iran are situated on an active earthquake region. Masonry type structures are very common on these countries, especially on the rural areas. During the last earthquakes, several masonry type houses were collapsed, causing loss of life and property. Strengthening methods of masonry houses were discussed in this study. The paper summarizes the results of a experimental programme carried out on models, scaled 1/10, of one-storey masonry buildings. First specimen tested was the reference specimen and used for comparison purposes. Other specimens contained several strengthening strategies. A total of 9 specimens were tested. The results allow to assess the efficiency of the various strengthening techniques employed.
