“…(1996) noted that structural masonry assessment practice should be evaluated by testing, and 34 because the construction of exact replicas of historic unreinforced masonry bearing walls is 35 impractical, in-situ testing is frequently the most viable experimental option. Despite this notion, 36 in-situ out-of-plane tests on full-scale URM walls have not commonly been conducted, and most 37 available literature reports experimental programs that consist of in-situ testing for material 38 characteristics (Corradi et al 2003;Chiostrini et al 2003) or non-destructive testing of masonry 39 structures or sub-assemblies (Lopes et al 2009; Carpinteri et al 2005). A third approach thatretains the existing masonry materials and construction quality but disrupts the support 41 conditions and existing stress states has been to extract masonry wall panels and transport them 42 to testing facilities (Abrams et al 1996).…”

The fourth building was a reinforced concrete frame structure 7 with pre-cracked clay block partition walls in addition to partition walls that appeared 8 undamaged. The test program was comprised of testing five one-way vertically spanning solid 9 URM walls from the group of three URM buildings and testing four two-way spanning URM 10 partition walls from the reinforced concrete frame building. All walls were tested with their 11 original support conditions, but three one-way spanning walls were additionally re-tested with 12 modified support conditions. These additional tests allowed the effects of wall support type to be 13 investigated, including the influence of a concrete ring beam used at the floor levels and the 14 influence of wall to timber diaphragm anchorage by means of grouted steel rods. Several walls 15 were next retrofitted by adding either near-surface mounted (NSM) carbon fiber reinforced 16 polymer (FRP) strips or NSM twisted steel bars (TSB), and were then re-tested.

“…In this model, the crack direction rotates with the principal strain axes [37,38,39], and it embodies several possible non-linear stress-strain relationships for the compressive and tensile behaviours. TSRCM is often used in the numerical modelling of historical constructions, where the compressive behaviour of masonry is in general represented with a parabolic relationship [40,41]. However, this relationship was shown to be excessively stiff and incapable of representing the large non-linear behaviour of earthen materials [8,42].…”

Abstract:The paper reviews some recent numerical applications for the interpretation and exploitation of acoustic emission (AE) monitoring results obtained from historical masonry structures and materials. Among possible numerical techniques, the finite element method and the distinct method are considered. The analyzed numerical models cover the entire scale range, from microstructure and meso-structure, up to full-size real structures. The micro-modeling includes heterogeneous concrete-like materials, but mainly focuses on the masonry texture meso-structure, where each brick and mortar joint is modeled singularly. The full-size models consider the different typology of historical structures such as masonry towers, cathedrals and chapels. The main difficulties and advantages of the different numerical approaches, depending on the problem typology and scale, are critically analyzed. The main insight we can achieve from micro and meso numerical modeling concerns the scaling of AE as a function of volume and time, since it is also able to simulate the b-value temporal evolution as the damage spread into the structure. The finite element modeling of the whole structure provides useful hints for the optimal placement of the AE sensors, while the combination of AE monitoring results is crucial for a reliable assessment of structural safety.
