Blast Protection of Unreinforced Masonry Walls: A State-of-the-Art Review
| | Test charge weight (kg) | Charge size (kg) | Standoff (m) | Thickness (mm) | Failure criteria |
| | Test 1: Y2 | 2 | 1 | 0 | Control wall severely collapsed above burst height without front face fracture. | | Test 2: TQ-Z-J-D-5 | 5 | 1.0 | 3 (partially) | Wide crack propagated completely the thickness of the wall with large deformation. The polyurea layer is intact with some tensile strain marks. | | Test 3: TQ-Z-J-2-4 | 8 | 1.0 | 3 (fully) | The initial crack occurred at the center of the top without deformation. | | Test 4: TQ-Z-J-1 | 20 | 1.0 | 3 (fully) | The wall rotated about bottom and severely collapsed due to overload. Polyurea was torn and separated completely from the front face. | | Test 5: TQ-Q-W-2 | 5 | 10 | 0 | The wall presented mortar joint separation and would reach the critical state of collapse due to large deformation. | | Test 6: TQ-Q-J-2 | 5 | 3.0 | 3 (fully) | The wall underwent large deformation with side parts warping and disengaging from columns. There was no tearing of the polyurea. |
