Technique Research on High Strength Low Alloy Structural Steel Used in Semi-Rigid Guardrail

Abstract:

The technical and economic feasibility of high strength low alloy structural steel is analyzed used in highway semi-rigid guardrail. In principle of improving safety performance and reducing cost, a kind of high strength low alloy structural steel guardrail is designed. Through the finite element simulation method, the safety performance of this guardrail structure is validated to satisfy the grade-A conditions (160kJ kinetic energy). Compared with the guardrail of same protection level made of ordinary carbon structural steel, high strength low alloy structural steel guardrail can reduce the probability of penetrating when the accident vehicle impact the guardrail and decrease the accident damage, the steel consumption is above 20% lower and the construction cost can be saved as well, thus, remarkable economic and social benefits can be obtained.
