Static cyclic in-plane shear response of damaged masonry walls retrofitted with NSM FRP strips – An experimental evaluation

Numerical and experimental investigation on seismically damaged reinforced concrete wall panels retrofitted with FRP composites

“…The experimental program presented here uses six 1:1.2 scaled elements of PRCWP (7)(8)(9)(10)(11)(12) that were reinforced and casted according to Romanian Project Type 770-81 [29], [30]. The specimen outlines and reinforcement details are presented in Todut et al [27,28].…”

“…Recent research on reinforced concrete walls strengthened with EBR-FRPs were conducted by Mohammed et al [3], Li and Lim [4], Dan [5], Altin et al [6], Sas et al [7], Nguyen et al [8] and others. Several NSMFRPs studies were conducted by Sas [9], Konthesingha et al [10], Griffith et al [11], Lee and Cheng [12], Sakar et al [13], Stoian et al [14], Florut ß et al [15] and others, whereas the TRM technique was investigated by Bernat-Maso et al [16], Bernat et al [17], Elsanadedy et al [18], Larrinaga et al [19], Corradi et al [20] and others. Other research presented by Wang et al [21], Carrillo and Alcocer [22], Demeter [23], Guan et al [24], Doh and Fragomeni [25], Parulekar et al [26] investigated reinforced concrete walls with or without openings.…”

A review of FRP strengthened concrete structures under extreme loading

“…The FRP strengthening system can significantly improve the strength, displacement capacities and energy dissipation ability for concrete and masonry walls (ElGawady et al 2007, Hamed and Rabinovitch 2008, Capozucca 2011, Konthesingha et al 2013, El-Sokkary and Galal 2013, Umair et al 2015, and it is especially effective for masonry walls (Hamed andRabinovitch 2008, Bui et al 2015). If sufficient FRP strengthening is applied, the failure can change from a shear dominant mode to a flexural dominant mode.…”

Application of Ordinary Fiber-Reinforced Concrete Layer for In-plane Retrofitting of Unreinforced Masonry Walls: Test and Modeling

“…El-Diasity et al [16] investigated the in-plane behavior of confined masonry walls retrofitted using low-cost ferrocement and Glass Fiber Reinforced Polymer (GFRP) systems through cyclic in-plane tests. The in-plane behavior of URM walls retrofitted by near-surface-mounted FRP or twisted steel bars is also addressed by a number of researchers [17][18]. Some researchers have used fabric-reinforced-cementitious-matrix, polymer textile reinforced mortar (TRM) overlay or polymeric net reinforced cementitious matrix for in-plane strengthening of URM walls [19][20][21][22][23][24][25].…”
