| 摘 要： | 提出一种新的方法，旨在提高公路桥墩的圆形钢柱的抗震性能，并且辅以试验证明。该方法中，在桥墩中间放置一个特殊的受压构件以承担上部结构传来的轴向荷载。结果，在钢板非弹性屈曲变形中轴向荷载的影响可以被很好地控制。这个特殊的抗压构件由一个预应力钢管混凝土（PC-CFT）组成。

| Abstract: | This paper presents a new method aimed at improving seismic resisting characteristics of circular-shaped steel columns representing highway bridge piers and an experimental investigation carried out to validate it. In this method, a special compression member is placed in the middle of the pier in order to take the axial load from the superstructure. As a result, the influence of axial load on the inelastic buckling deformation of plates can be greatly controlled. The special compression member consists of ... |
