Abstract

In order to study the transverse distribution of crash barrier along the bridge structure and its contribution to the bearing capacity of the main beam structure. Based on the load test of a reinforced concrete hollow slab bridge, this paper studies the influence of the crash barrier on the main beam structure, establishes the finite element model, analyzes one by one, and then compares one by one.The results show that the guardrail is distributed in a triangle along the transverse width of the bridge. The conclusion can provide a theoretical basis for the normal calibration coefficient.
