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。
Establishing a restoring force model that can effectively consider the typical hysteretic characteristics such as strength degradation, stiffness degeneration and pinch-in effect is the key and foundation for seismic design and seismic performance evaluation of engineering structures. In this paper, the research status of uniaxial, biaxial and torsional-torsional coupled Bouc-Wen-Baber-Noori (BWBN) models for engineering structural inelastic seismic response analysis is reviewed firstly. Then, the influence of BWBN model on model parameter identification, Earthquake demand analysis and inelastic seismic response spectra. Finally, the future research work of BWBN model is prospected.
