“…All the above is investigated experimentally, analytically and numerically in the present study, for the case of masonry walls subjected to out-of-plane cyclic loading. More details on the experimental part for the case of out-of-plane, and also related to in-plane loading are given in [5,6]. The experimental results are found in good agreement with analytical modeling as well as finite element modeling; both modeling approaches may be used in future studies to perform detailed parametric analyses.…”

Taking into consideration the seismic vulnerability of older buildings and the increasing need for reducing their carbon footprint and energy consumption, the application of an innovative system is investigated; the system is based on the use of textile reinforced mortars (TRM) and thermal insulation as a means of combined seismic and energy retrofitting of existing masonry walls. Medium scale tests were carried out on masonry walls subjected to out-of-plane cyclic loading. The following parameters were investigated experimentally: one-sided versus two-sided insulation and/or TRM jacketing, placement of the TRM outside the insulation or in a sandwich form (over and under the insulation), as well as the displacement amplitude of the loading cycles. A simple analytical method is developed and is found in good agreement with test results. Additionally, numerical modeling is carried out and is also found in good agreement with test results. From the results obtained in this study the authors believe that TRM jacketing may be combined effectively with thermal insulation, increasing the overall strength and energy efficiency of the masonry panels in buildings.

“…Finally, the use of TRM jacketing for strengthening of masonry infills has been combined with thermal insulation materials for providing concurrent seismic and energy retrofitting. The concept of combined seismic and energy retrofitting with advanced materials was proposed for the first time and investigated experimentally for the case of masonry subjected to out-of-plane (Triantafillou et al 2017) and in-plane (Triantafillou et al 2018) loading. These studies introduced for the first time the combination of TRM with standard or even highly fire-resistant thermal insulation materials.…”

Textile reinforced mortars (TRM), also known in the international literature as textile reinforced concrete (TRC) or fabric reinforced cementitious matrix (FRCM) materials, have been widely studied during the last two decades as they constitute a promising alternative to the fiber reinforced polymer (FRP) retrofitting solution for strengthening of reinforced concrete members. This paper presents a state-of-the-art review on the strengthening of concrete structures with TRM. First, the tensile and bond behavior of TRM is described. Next, an overview of studies on the use of TRM for flexural, shear, confinement, and seismic retrofitting of concrete or RC members is included, and the key parameters are investigated.

“…Textile Reinforced Mortar (TRM), also termed Fabric Reinforced Cementitious Matrix (FRCM) composites (Triantafillou, 2016) has been recently applied coupled with insulation panels for seismic and energy retrofit purposes (Triantafillou et al, 2018;Gkournelos et al, 2020). The first experimental results demonstrated that this combined solution increases the seismic safety level of the retrofitted construction, even considering the application on one side only and with different dispositions of the TRM system with respect to the insulation layers (see Figure 10).…”

“…Moreover, the curing process of geopolymer may produce a considerable quantity of salts if the chemical constituents are not carefully evaluated (Miranda et al, 2017). Such salts have a damaging impact not only on the existing substrate, especially for historic FIGURE 10 Scheme of the TRM structural and energy retrofitting solution: (A) masonry wall (Triantafillou et al, 2018); (B) RC frame (Pohoryles et al, 2020).…”

The European building stock presents pertinent issues needing suitable strategies to be solved. In detail, this regards seismic safety and energy efficiency of buildings to ensure more liveable and safe cities, which represents an important goal for modern societies. Energy performance includes both comfort and saving, the latter required for a more responsible resource consumption within the building sector, having a considerable contribution to the total demand. Current strategies do not seem to be able to simultaneously solve such aspects satisfactorily, both for higher economic requirements and poor technical feasibility implied by separated and disharmonious interventions. Thus, a holistic perspective should be adopted to pursue such an ambitious objective, which has recently gained increasing attention among researchers. Current requirements are firstly highlighted to show the need for an integrated approach to building retrofit. Secondly, a critical review of integrated strategies combining seismic and energy refurbishment proposed in the literature is reported. Then, special issues are discussed, including the feasibility of an integrated approach applied to heritage buildings. This study revealed that a fully efficient strategy for integrated retrofit has not still been proposed in the literature and there are several open issues to be solved. However, current solutions may be further developed to improve them and the several options currently available demonstrated the increasing attention and importance of the topic. Finally, concluding remarks on this research topic have been drawn to promote future studies.
