Available in PDF, EPUB and Kindle. Book excerpt: "The Federal Highway Administration initiated this contract with the objective to crash test and evaluate several terminals, transitions, and longitudinal barriers to NCHRP Report 350. NCHRP Report 350 specifies crash tests and evaluation criteria for three performance levels for terminals and six performance levels for transitions and longitudinal barriers. The buried-in-backslope terminals evaluated were the G4 on steel posts and wood blockouts with a rub rail and a 6 to 1 vee ditch and the G4 with steel posts and wood blockouts with a 4 to 1 slope. Both met specifications for NCHRP Report 350 test 3-35. The 3-strand New York cable terminal was evaluated and met requirements for NCHRP Report 350 test 3-34. The transitions evaluated under this contract included the vertical wall transition (W-beam with W-beam rub rail and steel posts), the vertical flared back transition (W-beam with channel rub rail, steel posts, and routed wood blockouts), the Pennsylvania Department of Transportation (DOT) transition (vertical flared back concrete parapet with W-beam, rub rail, steel posts, and routed wood blockouts), the Nebraska thrie beam transition (vertical wall parapet with thrie beam), and the Connecticut W-beam transition (NJ-shape wall with W-beam and channel rub rail). All the transitions met the required criteria for NCHRP Report 350 test 3-21, except for the vertical flared back transition. The MB1 median cable barrier chosen for evaluation was the Washington State DOT (WSDOT) cable barrier with a New York cable rail terminal. The thrie beam guardrail with steel posts and routed wood blockouts and the strong wood post thrie beam guardrail were also evaluated. The cable barrier and both thrie beam guardrails met the required specifications for NCHRP Report 350 test 3-11. The modified thrie beam guardrail with 2.1-m-long W150x14 steel posts and W360x33 blockouts (Design No. SGR09b) was evaluated and met specifications for NCHRP Report 350 test 4-12. Construction details for all the terminals, transitions, and longitudinal barriers evaluated are reported herein. Also included are details of the crash tests performed and the assessment of each test."--Technical report documentation page.
Book Synopsis NCHRP Report 350 Test 3-11 of the Washington Type 2 Concrete Barrier by : Delbert Lance Bullard
Download or read book NCHRP Report 350 Test 3-11 of the Washington Type 2 Concrete Barrier written by Delbert Lance Bullard and published by . This book was released on 2001 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two crash tests are required to evaluate portable concrete barriers, such as Washington Department of transportation (WsDOT) Type 2 concrete barriers, to NCHRP Report 350 test level three (TL-3). NCHRP Report 350 test designation 3-10 involves an 820 kg passenger vehicle impacting the critical impact point (CIP) of the length of need (LON) section at a nominal speed and angle of 100 km/h and 20 degrees. NCHRP Report 350 test designation 3-11 involves a 2000 kg pickup truck impacting the CIP of the LON section at a nominal speed and angle of 100 km/h and 25 degrees. Finite element analysis using LS-DYNA was used to simulate NCHRP Report 350 test designation 3-11 with the 2000 kg pickup truck on the standard Type 2 concrete barrier with a pin and loop connection and two modified pin and loop connections. In subsequent full-scale crash tests, both the standard and a modified concrete barrier met the evaluation criteria of NCHRP Report 350 for Test 3-11. For each of the two pin and loop configurations crash tested, the Washington Type 2 concrete barrier met the evaluation criteria of NCHRP Report 350 for test 3-11.

Available in PDF, EPUB and Kindle. Book excerpt: This report documents the results of a crash test of a Modified Thrie Beam guardrail with an 8000-kg single unit truck impacting at a nominal speed and angle of 80 km/h and 15 degrees. This is the strength test for Test Level Four (TL-4) in NCHRP Report 350. It was found that the test results met all of the evaluation criteria. The single unit truck was smoothly redirected and remained upright. Detailed drawings are presented for documentation and to facilitate implementation.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project was to assess the performance of both the ODOT GR-2.2 guardrail and the ODOT GR-3.4 transition system under NCHRP Report 350 test level 3 (TL-3) conditions, propose any modifications that would improve their crashworthiness and, ultimately ensure that the final designs qualify for use on the National Highway System (NHS) as TL-3 systems. Finite element analyses of the guardrail and transition system were performed using the LS-DYNA finite element software to simulate NCHRP Report 350 Test 3-10 and Test 3-11 impact scenarios. The analysis results indicated that the original ODOT GR-2.2 guardrail would successfully meet all NCHRP Report 350 test level 3 safety criteria. The analyses also indicated that the performance of the system could be significantly improved with simple modifications to the guardrail. The integrated system of the Nested Type 5 Guardrail with Tubular Backup and the ODOT GR-3.4 transition was considered the most practical and feasible design improvement and was therefore recommended as a final design.

Download or read book NCHRP Report 350 Test 3-21 of the New York Four-Rail Bridge Rail Transition written by C. Eugene Buth and published by . This book was released on 1999 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the details of the New York Four-Rail Bridge Rail transition and results of the pickup truck test: NCHRP Report 350 test designation 3-21, which is the 2000-kg pickup truck impacting the CIP of the transition at 100 km/h and 25 degrees. The New York Four-Rail Bridge Rail Transition did not meet occupant risk criterion D and vehicle trajectory criterion K for NCHRP Report 350 test designation 3-21. Due to the significant amount of overall deformation of the occupant compartment, separation in the floor pan, and partial ejection of the dummy through the door which was pulled open at the hinges, overall damage to the vehicle was judged to hav epotential for causing serious injury to occupants. This severe damage resulted from vehicle snagging on the rail splice joints and bolt heads that protruded after the rail element was partially collapsed.
