“…It should be noted that the real structure is complex, therefore, the selection should be decided together by both the house owner and engineer. All in all, a good reinforcing technique must consider the factors of aesthetics, function, strength, ductility and stiffness and the cost requirements [83].…”

“…In the simulation work of retrofitted masonry, the original masonry element and retrofitting masonry are normally modelled separately. In the work of Wang et al [54,83], the strengthening layer was modelled as the same with the original masonry wall. The collar joint, which combines the two masonry leaves together, was modelled as a cohesive interface element.…”

Masonry structures commonly exist in reality and still are popular all over the world. It has been reported and studied that these buildings are vulnerable to strong external loadings imposed by earthquake, strong wind, blast etc. In the past few decades, different seismic retrofitting and strengthening approaches for masonry structures/elements have been developed and implemented. In this paper, the previous studies on the strengthening/retrofitting techniques for Unreinforced Masonry (URM) buildings subjected to seismic and extreme loads are reviewed and summarized. The fundamental concept of strengthening/retrofitting approaches is to (i) reduce the influence of external loading, (ii) upgrade the individual element's load-carrying capacity and (iii) improve the integrity of masonry structure. A comparison and assessment of the advantages and disadvantages of each method is presented to identify the most suitable method in different cases. It is expected that this paper will provide some helpful information and guidance for the engineers and householders in choosing an appropriate technique in strengthening/retrofitting URM structures.

“…(Tomaževič and Zarnic 1985;Shing et al 1989;Voon and Ingham 2006;Haach et al 2007 andShrive 2010). However, while some concluded that shear reinforcement can improve the maximum in-plane shear capacity (Priestley andBridgeman 1974 andKhattab andDrysdale 1993), others have concluded that providing horizontal shear reinforcement has a negligible effect on the shear strength (Nolph and ElGawady 2012;Hidalgo-Leiva et al 2016;Shrive 2015 andRizaee andShrive 2018) or its effect D r a f t on shear strength is not completely clear (Shing et al 1989;Foltz and Yancey 1993;Schultz et al 1998 andHaach et al 2010). The results of the experiments conducted by Rizaee (2015) were therefore analyzed carefully to investigate the effects of end-anchorage, and amount and distribution of horizontal reinforcement on the shear strength of partially grouted squat masonry shear walls failing in diagonal shear.…”

The effect of the amount, distribution, and end anchorage conditions of bond beam reinforcement on the behaviour of concrete masonry shear walls

The behaviour of square shape partially grouted concrete masonry shear walls with fixed end boundary conditions subjected to constant average axial stress and cyclic lateral loading was investigated. Two replicas were tested of each combination of horizontal reinforcement ratio (0.12%, 0.06% and 0.03%) and four end anchorage conditions (straight, 90°, 180° and shear studs). The behaviour of the walls was compared in terms of strength, ductility, stiffness and dissipated energy. While the effect of horizontal bar size was greater than that of end anchorage, neither improved end anchorage nor the smaller bar size increased yielding at critical locations on the rebars. The highest course of the wall should be reinforced and grouted as it improves performance of the walls. In addition, the amount of horizontal reinforcement did not significantly affect the strength of the shear walls, therefore changes to the shear design equations in the Canadian Standard are recommended.

“…Different methods have been used to model the phenomenon, including: elastic theory, plastic theory, limit state and equilibrium, finite elements using macro-and micromodeling for masonry, experimental formulae, etc., and many references from many years ago to present can be found in the scientific literature related to this approach: e.g. tying walls [21,22], concrete jacketing of walls [23], epoxy and cementitious fiber composites [24,25,26,27,28,29], prestressing techniques [30], or design of new units [31,32]. However, these methods and techniques are sometimes rather complex and difficult to replicate without the help of precise numerical models able to reproduce a building's actual behavior.…”

Abstract.A novel seismic isolator is presented to detach the structural behavior from the infill effect during earth movements, with the aim of avoiding strong interactions. An experimental campaign was carried out to determine the influence of this isolator during the early stages of the seismic response of masonry-infilled steel frames, testing different configuration schemes to assess their effectiveness in terms of overall isolation, reduction of peak loads, strain levels and energy dissipation. The device was found to hinder the formation of the damaging diagonal compression struts by absorbing the relative displacements between frame and infill. The results achieved show that seismic interaction between infill panels and the structural skeleton can be faced from an isolation point of view.
