门式钢架厂房设计

武汉科技大学本科毕业设计I摘要本设计是轻型钢结构厂房，采用的是轻型门式钢架体系，建筑质量轻，强度高且跨度大，钢结构建筑施工工期较短，相应的降低投资成本,在国内有着较为广泛的应用前景。轻型钢结构屋面荷载较轻，所以杆件截面较小、较薄。它除了具有普通钢结构自重较轻、材质均匀、加工制造简单、应力计算准确可靠、运输安装方便、工业化程度高等特点外，还具有用料较省、取材方便、自重更轻等优点。本设计主要为结构设计。结构设计部分包括结构选型和布置、荷载计算、吊车梁设计、抗风柱设计、檩条和墙梁设计、门式钢架设计、支撑设计、基础设计、节点设计。各部分都详细演算了主要构件的计算过程。本次设计图纸部分有：结构设计说明书、厂房平面图、立面剖面、节点详图、刚架施工图、吊车梁施工图、厂房檩条墙梁布置图、支撑布置图、基础平面布置图。关键词：轻型钢结构厂房；门式刚架；结构设计；门式钢架设计。武汉科技大学本科毕业设计IIAbstractThedesignforthelightsteelstructureplant,theuseoflightportalframesystem,theconstructionoflightsteelstructurelightweight,highstrength,large-span,steelstructureconstructionperiodshort,lowerinvestmentcosts,economicbenefits.InChinaithasamoreextensiveapplicationprospects.Lightsteelstructureoftheroofloadlighter,andthusasmallercross-sectionbar,thin.Inadditiontoitsordinarylighterweightsteelstructures,materialuniformity,accurateandreliablestresscalculation,simpleprocessing,ahighdegreeofindustrialization,transportandotherfeatureseasyinstallation,thegeneralalsohaseasymaterialtobeusedthantheprovinces,theadvantagesoflighterweight.Thedesignspecificationisstructuraldesign.Partofthestructuraldesign,includingprogramselection,thedesignofthecranebeam,purlindesign,pillarofwind-resistantdesign,corbeldesign,rigidframedesign(hand-countingcomputercomparison,combinationofinternalforces),thenodedesign.Chaptersdetailthemaincomponentsofcalculuscalculation.Foundationprogramsincludegroundhandling,foundationdesign.Partofthedesigndrawingsareasfollows:plantfloorplan,Nodeelevationprofilesanddetailed,FrameConstruction,wall-beampurlinplantlayoutmap,constructionofcranebeammap,supportlayoutmap,foundationplan,lime-soilcompactionpilelayoutmap.KeyWords:Lightsteelstructureplan；Portalframe；Structuraldesign；Rigidframedesign武汉科技大学本科毕业设计III目录摘要.................................................................IAbstract................................................................II1绪论...................................................................12结构选型及布置........................................................12.1结构选型........................................................12.2材料的选择......................................................12.3柱网布置........................................................22.4屋面布置........................................................22.5柱间支撑及布置..................................................32.6屋盖支撑及布置..................................................32.7墙面结构布置....................................................43荷载计算..............................................................43.1永久荷载统计....................................................43.2活荷载统计....................................................43.2.3吊车荷载.......................................................53.3整个厂房各部分作用的荷载（标准值与设计值）......................64吊车梁的设计..........................................................74.1内力计算............................................................74.2截面选型........................................................94.3截面验算.......................................................104.4加劲肋计算.....................................................124.5疲劳强度验算...................................................134.6挠度验算.......................................................144.7焊缝连接计算...................................................145抗风柱设计...........................................................145.1荷载计算.......................................................155.2内力分析.......................................................155.3截面选择.......................................................165.4强度验算.......................................................165.5稳定性验算.....................................................165.6挠度验算.......................................................176屋面檩条设计.....................................................176.1荷载...........................................................17武汉科技大学本科毕业设计IV6.1.2可变荷载.....................................................186.2荷载组合.......................................................186.2.11.2恒载+1.4屋面均布荷载.....................................186.2.21.0恒载+1.4风吸力荷载.......................................186.3析内力分.......................................................196.4截面选择和截面特性.............................................206.4.1选檩条.......................................................206.4.2应力计算.....................................................206.4.3受压板件的稳定系数...........................................216.4.4受压板件的有效宽度...........................................226.4.5有效面积的截面模量...........................................236.5强度验算.......................................................246.6稳定性计算.....................................................246.7绕度计算.......................................................256.8构造要求.......................................................257墙梁设计.............................................................257.1荷载计算.......................................................267.2内力分析.......................................................277.3截面选型及验算................
