“…The strength of the grout, size of aggregate and area of grouting can affect grout performance. Numerical modelling shows the spacing of vertical and horizontal grout has a nonlinear relationship with the shear capacity of a wall [18]. As for the net area of PGM, the TMS 402/602-22 standard [19] specifies that the web of a concrete masonry unit and the void space between two units should be accounted for [10].…”

“…Several studies have considered the effect of the size and location of openings on the behaviour of a shear wall. The presence of an opening can lower the peak load and increase wall deflection [18], [39], [48], [49], [50]. Increasing the size of the opening did not have significant impact on peak load, but could increase the height of the piers, which impacts the wall stiffness and cracking pattern [11], [18], [48], [49], [50], [51].…”

Although structures have been built from masonry for many years, little is still known about the behaviour of a wall subject to in-plane shear. This is particularly true of partially grouted concrete masonry. The factors that are known to affect the strength of this type of masonry are discussed with the varying results and interpretations highlighted. There is consensus that increasing axial stress increases the shear strength and reduces the ductility of the masonry. However, whether reinforcement (both horizontal and vertical) contributes to strength remains an issue of debate, as is the effect of aspect ratio. Most codes and standards do not differentiate fully grouted from partially grouted masonry, often over predicting the shear strength of the latter. Wall versus panel failure is not considered. Much work needs to be done to improve our understanding of this material subject to in-plane shear.

“…In the case of the openings’ irregular location, the analysis’s complexity increases significantly. Various analytical models based on flexural or shear failure are used to determine the load capacity of in-plane shear walls [ 35 ] (sometimes called SLC—shear load capacity [ 36 ]). A simple equilibrium model can be used to estimate the behavior of shear walls [ 37 ].…”

Research on the Behavior of Stiffening Walls in Single-Storey Buildings Made of Autoclaved Aerated Concrete (AAC) Masonry Units

Experimental identification of stiffening walls is often limited to studying single-wall models. However, these samples do not reflect many additional effects—torsion of the building and redistribution of internal forces. This paper presents the results of two full-scale buildings made of autoclaved aerated concrete (AAC) masonry elements. The primary purpose of the work was to determine the changes in the stiffness of the shear walls and to attempt the empirical distribution of loads on the stiffening walls. The intermediate goals were: a description of the crack morphology and the mechanism of failure, the designation of the stiffening walls’ behavior. It was shown that the first crack formed in the tensile corner of the door opening, and the subsequent cracks formed in the wall without a hole. Based on the changes in the value of the shear deformation angles, the phases of work of the stiffening walls were determined. The presented research results are only a part of an extensive study of stiffening walls in masonry buildings conducted at the Silesian University of Technology.
