摘要
对摆振自复位排架双层墩结构技术的数理模拟进行研究,首先简要介绍了该结构的概念及案例主要参数,并重点通过最大层间移位角、层间残存移位角、下层墩体关键断面纵筋响应及矮墩剪切损坏的风险评估等,对该双层墩数理模型的建立及主要参数时程进行比对分析,可为同类工程应用提供技术参考。
The physical and mathematical simulation of swing vibration self-resetting bent double pier structure technology is studied.First,the concept of the structure and the main parameters of case are briefly introduced.The establishment of mathematical model of the double pier and time interval of main parameters are compared and analyzed by emphatically performing the risk evaluation on the maximum interlayer displacement angle,remaining displacement angle of interlayer,longitudinal reinforcement response of key section of lower pier and shear damage of low pier,so as to provide technical reference for similar engineering applications.
