工程结构非弹性地震动力反应分析的BWBN模型

RECENT PROGRESS ON BWBN MODEL FOR STRUCTURAL INELASTIC SEISMIC RESPONSE ANALYSIS

  • 摘要: 建立一种能够有效考虑强度退化、刚度退化和捏拢效应等典型滞回特性的恢复力模型,是开展工程结构抗震设计和抗震性能评估的关键和基础。该文首先回顾了工程结构非弹性地震动力反应分析的单轴、双轴和平扭耦联Bouc-Wen-Baber-Noori(简称BWBN)模型的研究现状,然后介绍了BWBN模型在模型参数识别、概率地震需求分析以及非弹性地震反应谱等方面的最新研究进展,最后对BWBN模型的后续研究工作进行了展望。

     

    Abstract: Development of restoring force models including typical hysteretic behavior such as strength degradation, stiffness deterioration and pinching effect is the basis and a key problem for aseismic design and seismic performance evaluation of engineering structures. A review on uniaxial-, bidirectional-, and lateral-torsional Bouc-Wen-Baber-Noori (BWBN) models for structural inelastic seismic response analysis is given. The recent progress on application of the BWBN model in identification of model parameters, probabilistic seismic ductility analysis, and inelastic seismic spectra is introduced. Future works on the BWBN models are also discussed.
