钢管混凝土结构的特点及发展

:钢管混凝土是指在钢管中填充混凝土形成的构件它利用钢管和混凝土两种材料在受力过程中相互间的组合作用,充分发挥两种材料的优点,使其具有承载力高塑性和韧性好施工方便经济效果显著的优点在过去的几十年里,我国主要研究圆形截面的钢管混凝土结构的力学性能,取得了丰硕成果,颁布了有关设计规程,并在工程上得到广泛应用而对于方钢管混凝土结构,虽然方钢管对核心混凝土的约束不如圆钢管,但却在与梁连接的节点处理时更方便灵活在国外,对方钢管的应用研究已有较为成熟的设计方法,但在我国的研究则不多,目前尚无专门的构件设计方面的规定因此,很有必要开展这方面的研究为此,本刊特刊出了几篇有关方钢管混凝土力学性能研究的文章,既有较系统的理论分析,又有丰富的试验数据,以有关读者韩林海(150008):,,:CHARACTERSANDDEVELOPMENTOFCONCRETEFILLEDSTEELTUBESHanLinhai(HarbinUniversityofArchitectureandCivilEngineering150008)Abstract:Thecharactersofconcretefilledsteeltubes,anditsdevelopmentinscientificresearchandengineeringapplicationoflateyearsareintroducedinthispaper.Thedevelopmenttendencyinresearchispredictedinthemeantime.Keywords:concretefilledsteeltubeshighstrengthconcretefireresistanceseismicbehaviorthinwalledsteeltubestructuralsystem,,,,,,[1],*:30:1998-06-161IndustrialConstruction1998,Vol.28,No.10工业建筑1998年第28卷第10期(),[2-10],,[11],,,,;,11.1钢管高强度混凝土性能的研究(,,C60),,,,,,,,,,,,,,,,,,,,,,,50%,;,,50%,50%,,,60%,60%,,,[12~28]:,,1.2钢管混凝土耐火性能的研究,,[29~34],[35~37],,,,,,,,,,,2工业建筑1998年第28卷第10期,,,,[38~44],2,,,,200,,,2.1钢管混凝土在拱桥中的应用,:,,;,,,,,,,50,,420m,2.2钢管混凝土在高层和超高层建筑中的应用,:(1),,,,,;(2);(3),;(4)!!,:(87.5m(86.5m)(96.0m)(115.7m)(137m),70,278.8m,15.5m2,,,TwoUnionSquarePacificFirstCenter3,:3.1薄壁钢管混凝土结构的研究,(0.04~0.20),,,,,1/3~1/5,,,,,3钢管混凝土结构的特点及发展∀∀∀韩林海,,,:,,3.2钢管混凝土结构在火灾后的性能研究,,,,,,,,,,:,,,,,,,3.3钢管混凝土结构体系抗震性能的研究,,,,,3.4钢管混凝土结构体系在火灾下的性能研究,,,,,,,,3.5方钢管混凝土力学性能研究,,,,,,,,,,Eurocode4(1992),AIJ(1997),AISC(1994)[11],,,,,1,:,19962:,19943:,19894,1992(1):13~315,1985(2):25~314工业建筑1998年第28卷第10期6WakabayashiM.RecentdevelopmentandresearchincompositeandmixedbuildingstructuresinJapan.In:Proc.oftheInter.Confer.onSteelConcreteCompositeStructures,Slovakia,1994:237~24271997.108FurlongW.Designofsteelencasedconcretebeamcolumn.JournaloftheStructuralDivision.1968.1.ST19LukshaLK.Strengthanalysisofcompressedsteeltubeswithsolidandcircularconcretecore.Proc.oftheInter.In:SpecialityConfer.ofConcreteFilledSteelTubularColumns,ASCCS,Harbin,1988:19~2310KnowlesB,Park.Axialloaddesignforconcretefilledsteeltubes.JournaloftheStructureDivision,1970.10.No.ST1011ASCCSSeminar.Concretefilledsteeltubesacomparisonofinternationalcodesandpractices.Innsbruck,1997.912RussellBridge.Highstrengthmaterialsincompositeconstruction.In:ConferenceReportofInternationalConferenceonCompositeConstructionConventionalandInnovative,Innsbruck,Australia,1997.913Russellbridge,etal.Thinwalledcircularconcretefilledsteeltubularcolumns.In:ProcofanEngineeringFoundationConfer.onSteelConcreteCompositeStructures,ASCE,NewYork,1992:634~64914SheaMDO,RussellBridge.Localbucklingofthinwalledcircularsteelsectionswithorwithoutinternalrestraint.DepartmentofCivilEngineeringResearchReportNo.R739,theUniversityofSydney,1997.415SheaMDO,RussellBridge.Localbucklingofthinwalledsquaresteelsectionswithorwithoutinternalrestraint.DepartmentofCivilEngineeringResearchReportNo.R739,theUniversityofSydney,1997.316KilpatrickAE,RanganBV.Testsonhighstrengthcompositeconcretecolumns.SchoolofCivilEngineeringResearchReportNo.1/97.CurtinUniversityofTechnology,Perth,WesternAustralia,1997.317,,,1991(1):23~27518,,,1991(3):3~819,,,1993(3):8~1220CaiShaohuai,GuWeiping.Behaviorandultimatestrengthofsteeltubeconfinedhighstrengthconcretecolumns.In:Proc.ofthe4thInter.SymposiumonUtilizationofHighStrength/HighPerformanceConcrete,AFPC,AFREMandENPC,Paris,France,1996:827~83321PrionHGL,etal.Beamcolumnbehaviorandultimatestrengthofsteeltubesfilledwithhighstrengthconcrete.In:Proc.oftheFourthInter.ColloquiumonStability,USA,1989:439~44922SakinoKenji,etal.Behaviorofconcretefilledsteeltubularstubcolumnsunderconcentricloading.In:Proc.oftheThirdInternationalConferenceonSteelConcreteCompositeStructures,ASCCS,Fukuoka,1991:25~3023YasuoI,etal.Elastoplasticbehaviorofconcretefilledsteelcircularcolumns.In:Proc.oftheThirdInter.Confer.onSteelConcreteCompositeStructures,ASCCS,Fukuoka,Japan,1991:131~13624,,1995(5):99~10625,1997(11):39~4426,1995,(5):107~11627.,1997(2):107~11628,1997(5):107~11629KlingschW.Newdevelopmentsinfireresistanceofhollowsectionstructures.In:SymposiumonHollowStructuralSectionsinBuildingConstruction,ASCE,ChicagoIllinois,1985:1~3430FlalkeJ.Comparisonofsimplecalculationmethodsforthefiredesignofcompositecolumnsandbeams.In:Proc.ofanEngineeringFoundationConfer.onSteelConcrete(29)5钢管混凝土结构的特点及发展∀∀∀韩林海3,(2)TBSA,,(3)-,,1/30,(4),2(5),(6),1,1996(2)2TBSA(5.0)19963-:1219924,1996(6)5:[].:,19966:[].:,19957HSUCTT.TShapedReinforcedConereteMembersUnderBiaxialBendingandAxialCompression,ACI,Structural,Journal,1989,86(4)(5)CompositeStructure,ASCE,NewYord,1992:226~24131LieTT.StringerDC.Calculationofthefireresistanceofsteelhollowstructuralsectioncolumnsfilledwithplainconcrete.Can.J.Civ.Eng.1994(21):382~38532LieTT.FireResistanceofcircularsteelcolumnfilledwithbarreinforcedconcrete.J.ofStructuralEngineering,1994(120):1489~150933LieTT,ChabotM.Evaluationofthefireresistanceofcompressionmembersusingmathematicalmodels.FireSafty,1993(20):135~14934MeagherAJO#,BennettsId,HutchinsonGL,etal.Stevens.ModellingofConcretFilledTubularColumnsinFire,BHPR/ENG/R/91/
