马颖：基于Bayesian理论的弯剪破坏钢筋混凝土柱变形能力概率模型论文

本文主要研究内容

作者马颖,王东升,解河海,白卫峰（2019）在《基于Bayesian理论的弯剪破坏钢筋混凝土柱变形能力概率模型》一文中研究指出：为了准确预测地震作用下弯剪破坏钢筋混凝土(RC)柱的变形能力,基于Bayesian理论提出了一种建立柱类构件变形能力概率模型的方法。首先对已有RC柱变形能力公式进行评价并选作先验模型,再借助美国PEER柱抗震性能试验数据库中发生弯剪破坏的20根矩形截面RC墩柱的拟静力试验数据作为客观认识,应用Bayesian参数估计方法综合这两类信息进行推断,修正先验模型的偏差从而建立反复荷载作用下弯剪破坏RC柱变形能力的概率模型;采用Bayesian方法剔除影响修正效果不显著的因素以获得模型简化,达到对先验模型的动态更新。最后,讨论了不同形式修正项对修正效果的影响。结果表明,Bayesian方法既继承了先验信息的完备性,又利用了试验数据的准确性,建议的概率模型较已有公式能够更准确地预测弯剪破坏RC柱的变形能力,从而为RC柱抗震设计或评估中考虑能力不确定性提供了便利。
