摘要：

For　further　research　on　the　improved　Bouc-Wen　model,　a　method　of　parametric　identification　was　presented　and　the　secondary　development　program　was　developed　in　this　paper.　And　then　the　method　was　applied　to　the　practices　of　30　BRBs＇　experimental　data.　The　changed　trend,　range　and　the　average　values　of　parameters　of　the　improved　Bouc-Wen　model　was　presented　for　providing　reference　for　applying　improved　Bouc-Wen　model,　and　the　value　of　the　model　parameters　was　suggested　for　application　reference.　Base　on　the　finite　element　software　ABAQUS,　the　improved　Bouc-Wen　model　can　be　applied　according　to　the　UMAT.　©　2016,　Beijing　University　of　Technology.　All　right　reserved.
