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。AbstractThedesignforthelightsteelstructureplant,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...
