In this study, the effects of openings left on shear walls on frame behaviour were investigated. In this context, 5 models were determined to achieve 5 different free column lengths by keeping the frame/shear wall height ratio constant. Frames with 5 different shear wall heights are modelled using C# software language via SAP2000 OAPI. Analyses were made by adding wing walls with 1 cm increments to the openings which causing short column formation. The analyses were continued from the frame without wing wall to the filled frame. Thus behavioural change graphs based on the wing wall length of the frames were obtained. During the modelling, 1 cm2 mesh size has been selected for the force transfer between the wing wall and shear wall can be achieved correctly. Change of the displacement values and the internal forces in the sections where short column formation is expected are recorded with high precision. A total of 750 different analyses were performed in this context. As a result of these analyses, it was seen that the lateral displacement capacity decreased nonlinearly and the probability of short column formation increased due to the shortening of the free column length.

“…Masonry construction is popular around the world, but the use of mortared masonry presents numerous challenges. It is associated with difficulty in quality control, labour-intensiveness, relatively weak brickmortar bonds, and modelling complexities due to its composite nature [1][2][3]. For these reasons, research interest has increased in various mortarless masonry systems, especially in the last 20 years [4].…”

Masonry construction is popular around the world, but the use of mortared masonry presents numerous challenges. In recent decades, masonry construction systems incorporating interlocking masonry units have been proposed to eliminate mortar. The interlocking between masonry units can be achieved using specially shaped units. This paper presents a comprehensive experimental study to determine the behaviour as well as basic material properties of one such semi-interlocking mortarless masonry. The experiments included testings of ungrouted masonry units, prisms, and wallets. In addition, masonry prisms and wallets with grouted cores were also investigated to study the effect of grouting. A detailed description of the construction procedure is explained. The failure mechanisms, maximum strengths, force–displacement relationships, and modulus of elasticity of the samples are obtained and contrasted with the relevant results from the literature. Finally, recommendations are made that may assist material model development required for micro- and macro-modelling of mortarless masonry. The new information generated in this research will enable better understanding of the behaviour and properties of semi-interlocking mortarless masonry and will be useful for validating numerical models in future research.

“…A significant bracing action, affecting both the strength and stiffness, originates by this mechanism, as demonstrated by a large number of experimental investigations [1][2][3][4][5][6][7][8][9][10][11][12][13] and analytical-numerical studies [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. However, despite several modelling strategies available in the literature, going from pinned equivalent struts macromodeling to FE micromodeling [33][34][35][36][37][38], masonry infills are generally not accounted for in models because of the large amount of uncertainties arising during their structural identification.…”
