| 摘 要： | 在地震中，由于桥联间伸缩缝处过大的变位会造成桥梁破坏，所以需要在支座宽度不足的伸缩缝间设置适当的限位器，以限制伸缩缝间的相对位移。基于反应谱法提出了耗能型限位器的计算方法。通过动力时程分析表明，该方法计算结果对于限制预期大的地震作用下桥联间的相对位移有明显的效果。

| Abstract: | The collapse of bridges due to unseating at intermediate hinges during earthquake emphasizes the need to provide an adequate number of restrainers to limit the relative displacement between frames in a bridge with inadequate hinge seat width. In the paper, new design procedure based on response spectrum for restrainers with energy dissipation is put forward, The proposed methods result in restrainer designs that are more consistent with the results of dynamic analysis. |
