将高墩桥梁结构中所有的桥墩作为一个完整体系,通过研究桥墩体系在地震作用下的破坏同步性探索了桥墩体系抗震能力发挥的情况。根据破坏标准和破坏同步性系数,研究了基于强度方法设计的桥墩体系的破坏同步性,分析了其不足之处。在此基础上,提出了基于桥墩体系破坏同步性的抗震设计方法,并对该方法与基于强度的设计方法进行了对比分析。工程算例分析结果表明,该方法对于充分发挥桥墩体系中所有桥墩的抗震潜能是有效的。
Taking all the piers in the high pier structure as a complete system, the seismic performance of the pier system is explored by studying the synchronization of the failure of the piers system under earthquake action. According to the failure criterion and the synchronization coefficient of failure, the failure synchronization of bridge pier system based on the strength method is studied, and its shortcomings are analyzed. On this basis, the seismic design method based on the failure of the bridge pier system is proposed, and the method is compared with the design method based on the strength. The engineering example analysis results show that this method is effective in fully exerting the seismic potential of all piers in bridge pier system.
