Box-beam burster energy-absorbing terminal bridge pier protection system Rohde, John R ; Sicking, Dean L ; Reid, John D

By: Contributor(s): Publication details: Transportation Research Record, 2003Description: nr 1851, s. 74-82Subject(s): Bibl.nr: VTI P8169:2003 Ref ; VTI P8167Location: Abstract: A new box-beam burster energy-absorbing terminal (BEAT) bridge pier (BEAT-BP) protection system was successfully crash tested according to the safety performance criteria presented in National Cooperative Highway Research Program (NCHRP) Report 350. The system comprises two BEAT crash cushions and a frame that envelops the bridge piers. Because of the close proximity to the piers, the system has a footprint significantly smaller than those of the other available options. Three crash tests were considered necessary to evaluate the BEAT-BP protection system and were conducted successfully: a pickup truck critical impact point (CIP) transition test at a bridge pier (Test Designation 3-21), a pickup truck CIP test at the connection between the crash cushion and the tubular frame structure (Test Designation 3-38), and a pickup truck end-on test for the crash cushion (Test Designation 3-31). A total of four crash tests were conducted, including one failed test (Test BP-2). The BEAT-BP protection system performed satisfactorily in all three required crash tests, meeting all evaluation criteria set forth in the guidelines of NCHRP Report 350.
