Abstract: A barrier is constructed from a plurality of cell-like elements interconnected to form a rigid barrier under normal circumstances. The linkages between cells provides a friction-brake force which is exceeded upon application of a traumatic force such as a bomb blast. The linkages includes slots in each cell connecting adjacent cells with prestressed nuts and bolts to permit sliding relative movement between adjacent cells after a predetermined threshold force has been exceeded. A transverse reinforcing rod, having a series of plates along its length, passes through adjacent cells. The plates act as a viscous damper as they move through a filler material within the cells while the rod adds strength. The cells may be coated with a dry lubricant to control the static coefficient of friction. The ability of the cells to move protects the barrier from structural failure by dissipating the blast forces through the frictional work required to displace the cells.
