ChinaForestProductsIndustry林产工业，2023，60（08）：17-24传统木结构穿销式榫卯节点抗震性能分析周志鹏1陈波1*黄勇2刘伟1（1.贵州大学建筑与城市规划学院，贵州贵阳550025；2.贵州大学勘察设计研究院，贵州贵阳550025）摘要：为研究不同穿销类型榫卯节点的抗震性能，考察了榫高、榫厚、柱径对节点力学性能的影响，采用有限元软件建模对榫卯节点进行拟静力分析，得到3类试件的滞回曲线、骨架曲线、耗能能力等抗震指标。结果表明：3类穿销榫卯的滞回曲线均呈现明显的Z型，捏缩效应较明显，3类试件的承载力相差不大；榫高、榫厚、柱径对榫卯节点的承载能力有显著影响，节点承载能力随榫厚、柱径增大而增大，随榫高的增大先增大后减小；根据穿销榫卯的骨架曲线建立了节点的弯矩-转角双折线模型，探讨了榫高、榫厚、柱径对模型参数的影响。在木结构设计中，应综合考虑榫卯尺寸变化对节点力学性能的影响。关键词：穿销类型；抗震性能；拟静力分析；滞回曲线；双折线模型中图分类号：TS6文献标识码：A文章编号：1001-5299（2023）08-0017-08DOI:10.19531/j.issn1001-5299.202308004SeismicPerformanceAnalysisofTraditionalWoodenStructureTenon-mortiseJointwithPenetratingPinZHOUZhi-peng1CHENBo1HUANGYong2LIUWei1(1.CollegeofArchitectureandUrbanPlanning,GuizhouUniversity,Guiyang550025,Guizhou,P.R.China;2.SurveyandDesignResearchInstituteofGuizhouUniversity,Guiyang550025,Guizhou,P.R.China)Abstract:Inordertostudytheseismicbehavioroftenon-mortisejointswithdifferentpintypes,aswellastheinfluenceofthreeparameterssuchastenonheight,tenonthickness,andcolumndiameteronthemechanicalpropertiesoftenon-mortisejoints,inthisstudy,finiteelementsoftwaremodelingwasusedforthequasi-staticanalysisoftenon-mortisejoints,andtheseismicindexessuchashystereticcurve,skeletoncurve,andenergydissipationcapacityofthreetypesofspecimenswereobtained.Theresultsshowedthatthehysteresiscurvesofthethreetypesoftenon-mortisejointspenetratingpinshowedobviousZ-shape,andthepincheffectwasobvious.Thebearingcapacityofthreetypesoftenon-mortisejointswithpenetratingpinunderrepeatedloadwasnotsignificantlydifferent.Thetenonheight,tenonthicknessandcolumndiameterhadsignificantinfluenceonthebearingcapacityoftenon-...
