Popis: | This paper presents the results of full-scale blast load testing of partially grouted single-wythe and multiwythe insulated masonry walls. Three design sections were evaluated, as follows: (1) a 150-mm (6-in.) standard block masonry wall reinforced with 10-mm (No. 3) rebar at 80-cm (32-in.) maximum spacing, (2) a 200-mm (8-in.) standard block masonry wall reinforced with 13-mm (No. 4) rebar at 122-cm (48-in.) maximum spacing, and (3) a cavity wall consisting of 200-mm (8-in.) standard reinforced concrete masonry unit (CMU) wythe plus a 102-cm (4-in.) clay facing brick veneer with 52-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 285 cm (112 in.), seven blocks, in width×345 cm (136 in.), 17 courses, in height. Only the cells containing reinforcement were grouted. Three blast load experiments were conducted; each experiment tested one each of the three test panel designs. The loading varied si... |
