摘要本工程是以轻型门式钢架作为结构形式的单层工业厂房。厂房为单跨，内设5t梁式吊车一部。厂房为双坡屋面，除基础使用混凝土，其他所有主次要构件均为钢结构。本设计说明书包括建筑设计，结构设计和地基基础设计三部分。建筑设计部分具体为建筑平面形式的选择，厂房剖面设计，厂房立面设计，厂房的构造设计，门窗明细表。结构设计部分包括方案选择，吊车梁设计，檩条设计，抗风柱设计，牛腿设计，刚架设计，节点设计。各章节都详细验算了主要构件的计算过程。在结构设计中，对各种构件的基本的设计思路如下：(1)建立合理的力学模型，确定计算简图；(2)计算各种情况下构件危险截面的内力；(3)进行荷载效应组合，得到可能的最不利内力组合；(4)对构件危险截面进行内力验算，继而确定其具体尺寸(包括截面尺寸、板件厚度、螺栓直径及间距、焊脚尺寸及长度、疲劳验算等)。构件的尺寸选择一般是通过经验公式进行初选，然后进行验算调整直至其符合要求。关键词：轻型门式刚架；荷载组合；内力分析；结构设计与验算AAAAbstractbstractbstractbstractThisprojectisasingle-storyindustrialplantwhichusesLightPortalFrameasitsconstructionform.Theplantconsistsofonecrosses,whichissetwithonesofthookbridgecranes,andisdesignedasgableroof.allothermajorandminorelementstakesteelastheirmaterial.Thedesignspecification,includingarchitecturaldesign,structuraldesignandfoundationofthreeparts.Architecturaldesignfortheconstructionplanetosomeofthespecificformsofchoice,plantprofiledesign,plantdesignelevation,thestructureofplantdesign,doorandwindowschedules.Partofthestructuraldesign,includingprogramselection,thedesignofthecranebeam,purlindesign,pillarofwind-resistantdesign,corbeldesign,rigidframedesign,thenodedesign.Chaptersdetailthemaincomponentsofcalculuscalculation.Instructuraldesign,thebasicdesignideasofvariouscomponentsareasfollows:(1)Establishareasonablemechanicalmodelanddeterminethecalculationdiagram;(2)Calculatetheinternalforceofdangeroussectionundervariousconditions;(3)Carriedoutthecombinationofloadeffectandgettheworstpossibleinternalforce;(4)Calculateandchecktheinternalforceofdangeroussection,andthendecidethespecificsizesofthem(includingthesectionsize,thicknessofplates,boltdiameterandspacing,sizeandlengthofthefootsolder,fatiguecalculations,etc.).Componentsizesaregenerallyprimarilyselectedbytheempiricalformula,andthenareadjustedandcheckeduntilitmeetstherequirements.KeyKeyKeyKeywords:words:words:words:LightPortalFrame;LoadeffectCombination;Internalforceanalysis;StructuraldesignandverificationI目录1建筑设计...............................................................................................................................11.1工程概况......................................................................................................................11.2设计条件......................................................................................................................11.2.1气象条件..............................................................................................................11.2.2工程地质条件......................................................................................................11.2.3材料规格..............................................................................................................11.2.4施工条件..............................................................................................................21.3建筑设计......................................................................................................................21.3.1设计依据及设计指导思想.................................................................................21.3.2设计特点及方案..................................................................................................21.3.3构造说明..............................................................................................................82方案选择...............................................................................................................................92.1结构设计资料...........................................................................................................102.2柱网布置及抗风柱布置...........................................................................................112.3柱间支撑布置...........................................................................................................112.4墙架布置....................................................................................................................122.4.1墙架布置............................................................................................................122.4.2墙架构件设计....................................................................................................132.5屋面支撑....................................................................................................................132.6支撑的布置...............................................................................................................142.6.1屋面支撑的作用................................................................................................142.6.2支撑的布置........................................................................................................143吊车梁设计.........................................................................................................................173.1吊车梁资料...............................................................................................................173.2吊车荷载计算...........................................................................................................173.3内力计算.........................................................................................
