摘要：

The central green belt connecting twin bridges has effects on the rigidity and dynamic characteristics of the bridges, but the effects are usually ignored, resulting in unexpected dynamic performance or even structural resonance. In this paper, the mechanism of median strips as a connection role between twin bridges is analyzed. Finite element models of the twin bridges and median strip are developed to analysis the effects on the overall system. Experimental study of typical twin bridges with a median strip was conducted to explore the relationship between the median strip and the vibration. Based on these analyses, recommendations related to overall structural performance are made to ensure a safe and rational design for twin bridges with median strip especially on dynamic performance in the future.
