  • To improve large bridge traffic safety quality, the basic structure of a combined bridge guardrail was identified by theoretical calculations and type investigation. A number of guardrail structure optimization designs were conducted by using computer simulation based on finite element theory, and the crashworthiness of optimized guardrail was validated by full-scale vehicle crash test.Analysis result shows that the guardrail structure can effectively protect errant vehicle, and its crashworthiness can reach more than 420 kJ, which agrees with SA degree of relevant standard in China. The experiment also validates the validity and reliability of data extracted from computer simulation.
