Abstract

As a seismic force-resisting system (SFRS), reinforced masonry shear walls with masonry boundary elements (RMSW+BEs) were found to achieve enhanced strength, stability, and ductility levels compared to rectangular RMSWs. The seismic design of RMSW+BEs necessitates reliable experimental and analytical investigations of their reinforced masonry boundary elements (RMBEs). The axial monotonic and cyclic stress-strain curves of RMBEs are essential to predict the lateral cyclic response of RMSW+BEs. This research aims to investigate, experimentally and analytically, the axial monotonic and cyclic behaviour of RMBEs built with C-shape masonry blocks. Moreover, this research proposes monotonic and cyclic stress-strain models for unconfined and confined RMBEs subjected to axial compression loading. Furthermore, a numerical study was performed to assess the sensitivity of the nonlinear seismic response of RMSW+BEs to various wall configurations and design parameters.
This research’s experimental work involved investigating various parameters affecting the compressive strength of fully grouted concrete masonry prisms and the axial monotonic and cyclic behaviour of RMBEs. Forty-two masonry prisms and 69 RMBEs were tested. The studied parameters were the vertical reinforcement ratio, the confinement ratio, the cross-section geometry (i.e., square vs. rectangular RMBEs), the masonry bonding pattern, pre-wetting of dry RMBEs, various grout types, and the grout compressive strength. The results showed that RMBEs built with rectangular sections exhibited enhanced strain ductility and post-peak behaviour than square RMBEs. Besides, using low grout compressive strength significantly reduced the strain ductility and yielded sharp strength degradation of the RMBEs.
The RMBEs′ experimental results revealed that the monotonic stress-strain curves form envelope curves to their cyclically tested counterparts. The proposed monotonic and cyclic stress-strain models showed good-to-excellent agreement with the experimental results, predicting the envelope and cyclic stress-strain curves′ major characteristics.
The numerical study’s results showed that the seismic design of RMSW+BEs can be optimized through careful choice of their design parameters. Enhancing the RMSW+BEs lateral yield and ultimate capacities and the lateral effective stiffness can be achieved by increasing the vertical reinforcement ratio of the RMBEs and the masonry compressive strength. Contrarily, reducing the masonry strain at peak stress and/or the masonry modulus of elasticity greatly hinders the walls′ displacement ductility.
