摘要
连续刚构桥梁由于其造价较低,目前在我国得到广泛的应用.但是在高烈度地区跨越峡谷时,其桥墩通常较高,此时其抗震性能如何将成为设计人员关注的重点.论文以一座91m墩高的连续刚构为例,对其地震响应进行详细计算和分析.结果表明,该型式桥梁具有较好的抗震性能.
Continuous rigid-frame bridges are widely used in China because of its lower cost, but in high intensi- ty region where the pier is usually high, the earthquake-resistant behavior becomes the main concern of the desig- ner. The seismic response of a continuous rigid-frame bridge with 91 - m pier is calculated and analyzed in de- tail, showing that this type of bridge has excellent earthquake-resistant behavior.
