摘要本设计为常丰线缆有限公司生产车间进行肋梁楼盖设计。单向板肋梁楼盖由板、次梁、主梁以及竖向承重的柱或墙等构成。梁板结构是土木工程中常见的结构形式,例如楼(屋)盖、楼梯、阳台、雨蓬、地下室底板和挡土墙等。在建筑结构中得到广泛应用。本工业厂房柱网尺寸为6.3m×6.3m，横向3跨，纵向5跨，柱截面尺寸为400mm×400mm。根据任务书需要对肋梁楼盖进行结构设计。首先需要根据轴网布置进行结构的平面布置，确定板、主次梁构件的尺寸；然后分别对板、次梁、主梁进行设计计算。在进行设计计算时，首先进行荷载统计，然后进行内力计算，对于主梁还需要绘制内力包络图，根据计算结果进行配筋计算。关键词：单向板；弹性理论；塑性理论；肋梁楼盖ABSTRACTThisdesignisfortheribbedbeamfloordesignoftheproductionworkshopofChangfengCableCo.,Ltd.Theone-wayribbedbeamflooriscomposedofslabs,secondarybeams,mainbeams,andverticalload-bearingcolumnsorwalls.Beamslabstructureisacommonstructuralformincivilengineering,suchasbuilding(roof)covers,stairs,balconies,awnings,basementfloors,andretainingwalls.Widelyusedinbuildingstructures.Thecolumngridsizeofthisindustrialfactorybuildingis,with3horizontalspansand5verticalspans,andthecolumncross-sectionsizeis.Accordingtothetaskbook,carryoutstructuraldesignfortheribbedbeamfloor.Firstofall,itisnecessarytoarrangethestructureaccordingtothegridlayout,anddeterminethesizeoftheplatesandmainandsecondarybeamcomponents;Thenthedesigncalculationoftheplate,secondarybeamandmainbeamiscarriedoutseparately.Whencarryingoutthedesigncalculation,theloadstatisticsarecarriedoutfirst,thentheinternalforcecalculationiscarriedout,andtheinternalforceenvelopediagramisalsodrawnforthemainbeam,andthereinforcementcalculationiscarriedoutaccordingtothecalculationresults.Keywords：unidirectionalplate;elasticitytheory;Plastictheory;Ribbedbeamroof目录第1章设计资料............................................................................................................................11.1结构形式................................................................................................................................11.2平面布置................................................................................................................................11.2.1板厚的确定......................................................................................................................21.2.2次梁高宽的确定..............................................................................................................21.2.3主梁高宽的确定..............................................................................................................2第2章板设计................................................................................................................................42.1材料及其强度........................................................................................................................42.2荷载........................................................................................................................................42.2.1构造做法..........................................................................................................................42.2.2恒荷载..............................................................................................................................42.2.3活荷载..........................................................................................................
