Research on the Effect of Bridge Guardrail to Load Distribution

Article Preview

Abstract:

In order to study the effect of guardrail to main girder, simply supported beam load test is relied on to measure the deflection of main girder in different conditions, then whether guardrails involved in the stress of main beam or not in theory is analyzed to draw the conclusion that considering the guardrail in stress is closer to the actual stress of bridge and effects on stiffness of main girder are different in lateral bridge. Based on above four hypotheses are proposed and the guardrail along the bridge transverse triangular distribution to the 14% deck is in good agreement with the actual situation according to the equivalent height.
