Abstract

An impact dissipating bollard system includes a vertical stanchion and a composite energy-absorbing deformable cartridge configured to be positioned within a retaining foundation that includes a rigid core portion including a stanchion-receiving aperture and first and second projections extending from the rigid core portion. The first and second projections, together with the core portion, form the dumbbell shape. Energy-absorbing resilient elastic material surrounds the rigid core portion and is positioned within recesses within the first and second projections. The bollard system is configured such that impact energy is transferred from the vertical stanchion to deform the composite energy-absorbing deformable cartridge. The bollard system retaining foundation includes a reinforcing frame embedded in concrete and having a strength of least 30 MPa.
