摘要: 以框架式钢管混凝土桥墩及钢筋混凝土空心薄壁墩为研究对象,采用纤维单元建立了框架式钢管混凝土桥墩 及钢筋混凝土空心薄壁墩的非线性动力分析模型,输入3条地震波,计算得到了框架式钢管混凝土桥墩与钢筋混凝 土空心薄壁墩的线性及非线性地震时程响应,比较了不同类型桥墩地震响应的差异,讨论了框架式钢管混凝土桥墩 的地震反应特点

关键词: 框架式, 钢管混凝土桥墩, 地震响应, 非线性, 时程分析

Abstract: Takingconcrete-filledsteel tubular framepier andhollowthin-walledpier as theresearchprojects,thedynamic time-historyanalysismodelsareestablishedbyusingthefiberelement forconcrete-filledsteel tubularframepierandhollow thin-walledpier. Byinputting3actual seismicwavesintotheanalysismodels,thelinearandnonlineartime-historyresponse is analyzedrespectively. Basedontheanalysis results,theeffect of seismicresponsefor different piers is compared,and seismicresponsecharacteristicsof framepierarediscussed. Theresultsshowthat shearresponseappearslineardistribution, moment responserepresentsserrateddistributionandaxial forceresponseemergesstepwiseincreasealongthecolumnheight for framepier under theactionof waves. Shear,moment andaxial forceresponseof onecolumnof framepier arerelatively smaller comparedwithhollowthin-walledpier under theactionof waves.
