Partially grouted reinforced masonry (PG-RM) is a commonly used structural system in several seismic-prone countries. In recent years, experimental and numerical investigations have been conducted to identify the main parameters that influence their seismic performance. However, ...

There is a lack of reliability assessment of modern structural masonry design. Hence, a novel reliability-based calibration of the in-plane shear ultimate limit state for partially grouted reinforced masonry shear walls (PGRMSWs) is presented. This calibration allows for the prop...

This paper proposes specific ultimate shear strength expressions for partially-grouted reinforced masonry (PG-RM) shear walls that are bed-joint reinforced (BJR) and made with either multi-perforated clay bricks (MPCLBs) or hollow concrete blocks (HCBs). For each unit type, a set...

Eight partially grouted (PG-RM) concrete masonry walls were tested to study the influence of the strength and width of blocks, the wall aspect ratio, the horizontal and vertical reinforcement ratio, and the presence of edge elements (flanges). The results were analyzed in terms o...

This paper focuses on assessing the effects of the presence of a window-type opening on the shear behavior of partially-grouted reinforced masonry (PG-RM) shear walls. For this purpose, this work analyzes previously reported test results of three PG-RM walls tested under in-plane...
