Popis: This paper presents the results of large-deflection resistance testing of partially grouted single-wythe and multiwythe insulated masonry walls. Three design sections were evaluated under uniform pressure in a vacuum chamber test, as follows: (1) 150-mm (6-in.) standard block masonry wall reinforced with 10-mm (No. 3) rebar at 80-cm (32-in.) maximum spacing; (2) 200-mm (8-in.) standard block masonry wall reinforced with 13-mm (No. 4) rebar at 120-cm (48-in.) maximum spacing; and (3) a cavity wall consisting of 200-mm (8-in.) standard reinforced concrete masonry unit (CMU) wythe, a 100-mm (4-in.) clay facing brick veneer with 50-mm (2-in.)-thick extruded polystyrene rigid board insulation, and a 25-mm (1-in.) air gap between the structural wythe and the veneer. Each test panel was 3.5-m (136-in.) wide×3.0-m (116-in.) high with only the cells containing reinforcement grouted. Displacement at several locations through the height and width of each panel were recorded as each test panel was loaded to c...
