The thrie beam highway guardrail (also named as tri-beam crash barrier or tri-wave guardrail etc.) is a type of guardrail that is mainly installed along the highways around the world.

Development of the MGS Approach Guardrail Transition

A W-beam to thrie beam stiffness transition was developed to connect the Midwest Guardrail System (MGS) to a previously-approved thrie beam approach guardrail transition to bridge rail. This new stiffness transition was configured with standard steel posts commonly used by Evaluation of the Midwest Guardrail System stiffness A W-beam to thrie beam stiffness transition with a 102-mm (4-in.) tall concrete curb was developed to connect 787-mm (31-in.) tall W-beam guardrail, commonly known as the Midwest Guardrail System (MGS), to a previously developed thrie beam approach guardrail transition system.

Midwest Guardrail System W-Beam-to-Thrie-Beam Transition

Midwest Guardrail System W-Beam-to-Thrie-Beam Transition. For longitudinal barriers, it is common practice to use a standard W-beam guardrail along the required highway segments and to use a stiffened thrie-beam guardrail in a transition region near the end of a bridge.

The transition is achieved through the use of a product that bolts to the W-Beam at one end and to the Thrie-Beam at the other end. This transition is 2 m between post centres and is illustrated in Figures F5 and F15 of Appendix F of AS 3845:1999. 7.3.3 W-Beam to Concrete W-Beams are connected to a concrete barrier either through the use of a SDD 14b20 Steel Thrie Beam Structure Approachtransition section w-thrie beam traffic one way 3-5" 1-8" 6-3" w-beam 2 1 11 " 3 shall be filled with a treated timber blockout. blockout size is 1-6" x 2-0" x 3 ". the recess for a w-beam connection, which exists on some parapets of this type, thrie beam connection to bridge w beam transition

Thrie Beam Guardrail - Soft Resistance Against Impact

Thrie Beam Guardrail- a Visual Sign Implying Transition to Highways. Thrie beam guardrailfeatures its shape of three waves, which has an added corrugation on the basic of traditional W-beam. Compared to two-wave shape products, this one has a stronger construction and higher impact endurance. Triple T:Truck Thrie Beam TransitionThrie Beam Transition (Triple T), an 813-mm (32-in.) thrie beam transition, to meet PL2 requirements, are presented (2,3). Accord­ ing to the 1989 AASHTO guide, three tests are required on the tran­ sition to meet PL2. The test matrix includes one test with an 817-kg (1,800-lb) passenger car traveling 97 km/hr (60 mph) and at an
