Mechanical properties and numerical modeling of Fabric Reinforced Cementitious Matrix (FRCM) systems for strengthening of masonry structures

Tensile behaviour of mortar-based composites for externally bonded reinforcement systems

“…A limited number of laboratory studies have been carried out to date, devoted to material behaviour and composite-to-substrate bond performance [6][7][8][9][10][11] as well as to rehabilitation solutions for both masonry [12,13] and reinforced concrete [14,15] structures. Despite some real applications already exist [3,16,17], a deeper knowledge needs to be developed before mortar-based systems can be confidently used for safeguarding existing structures, especially when belonging to the built heritage.…”

Increase of load‐carrying capacity of masonry with textile reinforced rendering / Erhöhung der Tragfähigkeit von Mauerwerk mit textilbewehrtem Putz

“…Es gibt weiterhin einige Arbeiten, die die Effektivität von TRM-Bewehrung bei einer Belastung senkrecht zur Wandebene überprüfen [18], [40], [41] bis [44]. Zusätzlich wurden weitere Arbeiten zur Charakterisierung der besonderen Eigenschaften von bewehrten Mörteln durchgeführt, unter anderem zum Verbund zwischen Mörtel und Mauerwerk [45] bis [48] oder zur Zugfestigkeit der Mörtel [49]. Die meisten dieser späteren Arbeiten konzentrierten sich auf mit Carbonfasern bewehrte zementgebundene Matrices (CFRCM) oder stahlfaserbewehrte Vergussmörtel (SRG).…”

“…There are some works specifically oriented to evaluate the effectiveness of the TRM reinforcement against out-of-plane loading conditions [18], [40], [41] to [44]. Additionally, research has been carried out on the characterization of specific properties of reinforced mortars, such as the bond between the mortar and masonry [45] to [48] or the tensile strength of mortars [49]. Most of these latter works have been devoted to the study of Carbon Fibre Reinforced Cementitious Matrices (CFRCM) or steel reinforced grout (SRG).…”

Fibre-Based Sectional Analysis of Urm Walls With Single-Side FRCM Strengthening

“…At the scale of the structural application, numerous experimental and numerical activities have been conducted so far, and were mainly aimed to determine the increase in shear strength of URM walls strengthened with FRCM systems through diagonal compression tests [7][8][9]. In particular, it was found that the employment of FRCM systems typically led to an increase in shear strength in a variable range between 50% and 500% compared to the URM, also considering that the lower was the shear strength or stiffness of the non-reinforced samples, the greater increase in the reinforced samples was achieved.…”
