| 摘 要： | <正>交异性钢桥面板改造的问题在于既有钢板与第二个钢板的粘结,以降低应力和增加正交异性钢板的使用寿命。通过试验和分析,对梁的弯曲性能进行参数研究。试验考虑不同厚度、温度和跨度的影响。从试验结果可见,应力降低与温度无关。最小化第二块钢板的厚度及最大化粘结层厚度,可降低重量,增加组合结构的刚度,这是最有效的解决方法。组合梁的弹性性能和屈服荷载取决于钢板的性能,温度的影响不显著。然而,粘结层的受剪最终导致梁的破坏,而粘结层的性能受温度的影响较大。

| Abstract: | The renovation solution for orthotropic steel bridge decks studied consists of bonding a second steel plate to the existing steel deck in order to reduce the stresses and increase the lifespan of the orthotropic bridge deck.A parametric study was carried out on the flexural behav-iour of beams representing the renovation solution using experimental and analytical studies.The influence of different thicknesses,temperatures and spans was tested.The results obtained for the stress reduction factor show that it... |
