土木工程毕业论文工程设计-框架结构(一)

毕业设计说明书（毕业论文）一中科技实验楼结构设计摘要本设计为一中科技实验楼，为五层框架结构。建筑总高度为19.5m，建筑面积为4201.15mm2，室内外高差为0.45mm，本地区抗震设防烈度为8度，框架的框架等级为二级。首先根据提供资料及框架结构的优点确定框架布局及承重方案。再根据承重方案选择、构件截面尺寸选择、重力荷载代表值计算及横向框架侧移刚度计算确定所设计框架为规则框架体系。然后计算了水平地震荷载作用下一榀框架的内力分析并求出内力，做出内力图，计算竖向荷载(恒载、活载)作用下各杆端内力，用二次分配法进行内力分配，接着内力组合，找出最不利的一组或几组来进行构件截面设计。最后，用计算机软件（PKPM）对一榀框架进行计算，并绘制了楼板的配筋图等。关键词：框架结构；实验楼设计；内力组合；截面设计；力矩分配法TechnologylabbuildingintheNO.1middleschoolofxxxxxxAbstractThedesignistechnologylabbuildingforthefive-storyframestructureintheNO.1middleschoolofxxxxxxxx.Thetotalbuildingareaisabout4201.15squaremetersandthetotalbuildingheightis19.5meters,andthedifferencebetweeninsideandoutsideground毕业设计说明书（毕业论文）levelsis450millimeter.Theseismicfortificationintensitydesignis8degrees,theclassofframestructureisSecondclass.Firstaccordingtothedesignmatcrialwhichprovides,aswellasthemeritsoftheframeworkoflayoutandloadingprograms.Undertheprogramthenloadingthechoicebeamsizechoices,gravityloadsonbehalfofthecalculationofhorizontalandlateralstiffnessframeworkofthecalculationtodeterminetheframeworkforthedesignrulesframework.Thencalculatethehorizontalseismicloadsframeworkofthenextloadanalysisandinternalforcessoughtforces,internalforcesmadeplans,calculatedverticalload(constantload,liveload)undertherodendswiththeinternalforcesecondarydistributionmethodforinternalforcedistribution,Theninternalforcecomposition,identifythemostdisadvantagedgrouporafewgroupstobeamdesign.Finally,thecomputersoftware(PKPM)carriesononeframetomatchthemusclechart,thefloormatchesthemusclechartaswellasthestaircasematchesthemusclechartthestructuretoleavethechart.Keywords:framestructure;officebuildingdesign;sectiondesign；internalforcecombination；momentdistributionmethod毕业设计说明书（毕业论文）目录第一章建筑设计..................................................................................................................11.1满足建筑功能要求.......................................................................................................11.2采用合理的技术措施..................................................................................................11.3具有良好的经济效果..................................................................................................11.4考虑建筑美观要求......................................................................................................11.5建筑平面设计..............................................................................................................11.5.1使用房间平面设计要求....................................................................................11.5.2本设计根据具体情况做到以下几点................................................................21.6交通联系部分的平面设计..........................................................................................21.7建筑立面设计..............................................................................................................21.8建筑剖面设计..............................................................................................................3第二章工程概况和计算简图..............................................................................................42.1工程概况......................................................................................................................42.1计算简图......................................................................................................................42.1.1结构布置图.........................................................................................................42.1.2结构计算简图....................................................................................................7第三章重力荷载计算..........................................................................错误!未定义书签。3.1工程做法.......................................................................................错误!未定义书签。3.2重力荷载代表值计算..................................................................错误!未定义书签。3.2.11G的计算.............................................................................错误!未定义书签。3.2.22G的计算.............................................................................错误!未定义书签。3.2.33G、4G的计算..................................................................错误!未定义书签。毕业设计说明书（毕业论文）3.2.45G的计算...........................................................................错误!未定义书签。第四章结构构件刚度计算..................................................................错误!未定义书签。4.1材料选择.......................................................................................错误!未定义书签。4.2刚度计算......................................................................................错误!未定义书签。第五章横向水平作用框架下结构内力和侧移计算..........................错误!未定义书签。5.1横向水平地震作用下框架结构的内力和侧移计算...................错误!未定义书签。5.1.1横向自震周期计算.............................................................错误!未定义书签。5.1.2水平地震作用及楼层地震剪力.........................................错误!未定义书签。5.1.3水平地震作用下位移验算.................................................错误!未定义书签。5.1.4水平地震作用下框架内力计算.........................................错误!未定义书签。5.1.5梁端弯矩、剪力及柱轴力计算.........................................错误!未定义书签。第六章竖向荷载作用下框架结构内力计算......................................错误!未定义书签
