Test Results
Unreinforced and Reinforced Window and Wall Tie
Two further identical 3m x 3m x 225mm (10ft x 10ft x 9in) solid masonry walls each with a mild steel plate 'window' were constructed. One window used conventional mechanical bolts; the other was strengthened using Cintec Multibar Window anchors. Each wall was subjected to an explosion for a 6kg (18lbs TNT equivalent) charge at 1m (39in) stand off.
Reinforced and Unreinforced Hollow Block (CMU) Wall Test
Two identical 3m x 3m x 225mm (10ft x 10ft x 9in) hollow block (CMU) masonry walls were constructed. One wall was reinforced using Cintec Multibar anchors; Blast pressures from small charges near to the target produce very high pressures: Further tests are planned using very large charges at greater standoff. |
The other was left unreinforced. Each wall was subjected to an explosion from a 6kg (18lbs TNT equivalent) charge at 1.5M (59in) stand off) Post test photo of a cavity wall masonry cube reinforced by Blastec anchors subjected to a blast load from 5kg (11lb) explosives at 1.2m (4ft). |
