Stress–Strain Behaviour of Boundary Elements in Reinforced Block Masonry Shear Walls Under Uniaxial Compression
Reinforced masonry shear walls (RMSWs) constructed using hollow concrete blocks are commonly used in medium-rise and high-rise reinforced masonry buildings. Past research has shown that RMSWs can be used as an effective seismic force resisting system (SFRS) as they can dissipate stable energy through ductile inelastic deformations. The seismic performance of RMSWs can be enhanced by special boundary elements, which are either barbell sections connected to the wall or integrated within the wall ends. The knowledge of stress–strain behaviour of boundary elements subjected to uniaxial compression is needed to accurately estimate the inelastic behaviour of RMSWs. This paper presents a detailed review of previous studies on boundary elements in RMSWs. The paper also presents an ongoing experimental programme performed by the authors, which includes testing of 4-course grouted reinforced block masonry prism specimens. The purpose of the testing programme is to study the effect of confinement on uniaxial strength and deformations in boundary elements. The influence of various parameters, including tie spacing, hook details, and grout strength on compressive strength and ultimate compressive strain of the prism specimens is investigated in the study.
