Highlights The effectiveness of FRCM composite for strengthening of masonry walls was investigated. A total of nine concrete masonry wall panels, 1.2m×1.2m in size, were tested under diagonal compression. FRCM and FRP strengthened walls were compared after normalizing the data. The experimental results were also compared with analytical model predictions.
Abstract In this paper, the in-plane behavior of un-reinforced concrete masonry walls externally strengthened with a fabric-reinforced cementitious matrix (FRCM) system is investigated. The experimental program consists of testing nine un-reinforced concrete masonry walls strengthened on both sides with two different FRCM schemes (one and four reinforcement fabrics). The analytical model as per ACI 549-13 is used to predict the shear capacity of the strengthened walls. The effects of design limitations in the approach proposed by ACI 549-13 are also discussed. Finally, experimental data from other research programs using fiber-reinforced polymer (FRP) composites are presented to demonstrate that when normalized shear capacity is related to a calibrated reinforcement ratio, the two overlay strengthening technologies match well.
