Comparison of Structural Response of W-Beam and Thrie-Beam Guardrail System

W-Beam 및 Thrie-Beam 가아드레일 시스템의 거동 분석

New Thrie-Beam guardrail section has been developed. The Characteristic of its geometry, energy absorbing capability and response to impact has been studied and compared with those of conventional W-Beam guardrail system. To compare the response to impact computer simulation using Barrier Ⅶ program was made. Stretch tests and static loading tests were conducted for the performance verifications.
