Abstract: A procedure for reconstructing run-off-road accidents into longitudinal W-beam guardrail systems was developed by estimating energy dissipation during an impact. Correlations were developed between the vehicle’s departure ...

Abstract: Breakaway supports are common devices used for dual-support signs located along the roadway. The sign system utilizes a fuse plate that is designed to support the wind loads on the sign as well as to allow the sign support ...

Abstract: An existing mountable safety barrier system, previously crash tested successfully on a wood bridge deck, was evaluated for use on a fiber reinforced plastic (FRP) bridge deck. In an attempt to avoid expensive full-scale ...

Abstract: A new box-beam guardrail end terminal, known as the box-beam bursting energy absorbing terminal (BEAT), was designed and shown to meet current United States impact safety standards according to guidelines provided by the ...

Abstract: A procedure for identifying critical impact points (CIP) for longitudinal barriers is presented. The procedure is based on computer simulations of longitudinal barrier impacts using the Barrier VII computer program. Critical ...

Abstract: Turned-down guardrail terminal sections were analyzed using LS-DYNA3D, a dynamic, nonlinear, large deformation finite-element modeling package with capabilities for simulating vehicular impacts into roadside hazards. A ...
