Detail
Corrugated beam guardrail can be approximately regarded as a continuous beam with point support on elastic foundation.The collision force acting on the guardrail at a certain Angle (10° ~ 20°) can be decomposed into the force acting on the guardrail vertically and parallel to the guardrail. The corrugated beam, the guardrail post and the foundation soil jointly bear the collision force, and the corrugated beam mainly bears the tension. The guardrail post mainly bears bending moment. In the process of collision, the guardrail post plays a very important supporting role. To improve the strength of the guardrail post, it can be achieved by increasing the moment of inertia, which is affected by the shape and area of the post section. Various countries use steel sections of different shapes for columns.
