抗震结构弹塑性反应谱的研究与应用
|
摘要
随着基于性能抗震设计理论的提出,以及对结构弹塑性地震反应研究的深入,弹塑性反应谱的研究得到更多的重视与发展。文中首先阐明了弹性和弹塑性反应谱的基本概念;其次,归纳和讨论了国内外弹塑性反应谱的研究现状,阐述了现有一些弹塑性反应谱研究的不足,并指出研究的基于Park和Ang双参数损伤模型的弹塑性反应谱,能够综合考虑了结构最大位移反应和结构累积滞回耗能的耦合作用,使弹塑性反应谱的研究进一步深化;最后,指出了弹塑性反应谱在基于性能抗震评估中的应用,但要将弹塑性反应谱应用于抗震设计规范中还存在诸多困难。
Along with the presented performance-based seismic design(PBSD) theory and further research about inelastic response spectra(IRS),research on IRS is got more and more attention and develops further.The concepts of elastic and inelastic response spectra were demonstrated first in this paper.Then,summarization and discussion of IRS at home and abroad was carried out.Some insufficiencies of known research about IRS were pointed out.Furthermore,some further studies on IRS were in progress based on Park and Ang damage model,which can consider coupling effect of maximum inelastic deformation and cumulative hysteretic energy.Finally,it is pointed that IRS can be used in performance-based seismic evaluation.However,it has a good many difficulties for applying to seismic design code.
