武汉科技大学城市学院毕业设计（论文）I十堰市张湾区实验中学教学楼结构设计摘要本次毕业设计是设计一栋中学教学楼,其中包括建筑设计和结构设计两部分。本教学楼共五层，层高3.9米,建筑面积4227.30㎡，建筑总高度为19.5米。采用钢筋混凝土框架结构,抗震等级为三级，抗震设防烈度为7度，整个设计包括建筑设计和结构设计两部分。建筑设计部分，首先根据建筑的使用功能和设计任务书确定初步布局，包括空间的整体形态及室内的空间布置等，然后根据使用的材料、做法等，进一步确定整体的布局、尺寸，以及平面、立面、剖面图等。结构设计部分，首先根据建筑设计以及其工艺要求，确定柱网以及一榀框架进行设计计算。确定计算简图，计算框架所承受的荷载，其中包括恒载、楼面（屋面）活载，在此基础上计算框架的内力，以及采用弯矩二次分配法求竖向荷载作用下的内力。关键词：建筑设计；结构设计；内力计算武汉科技大学城市学院毕业设计（论文）IIShiyanDistrictExperimentalMiddleSchoolTeachingBuildingStructureDesignAbstractMygraduationprojectisateachingbuildingformiddleschool,whichincludesarchitecturaldesignandstructuraldesign.Thisbuildinghasfivestoreys,eachstoreybeing3.9meters.Itcoversanareaof4227.30㎡,andthetotalheightis19.5meters.Weadoptthereinforcedconcretelframedstructure.Theclassesofseismicforthebuildingrates3andtheseismicfortificationintensityis7degrees.Mywholedesignismadeupoftwoparts,architecturaldesignandstructuraldesign.Asforthearchitecturaldesign,basedonitsusingfunctionanddesignspecification,Ifirstconfirmthepreliminarylayout,whichconsistsofintegralformofspaceandindoorspatialarrangementetc.ThenIdeterminetheoveralllayout,measurementandtheichnography,elevationandcutawayviewandsooninaccordanceofthematerialsandmethodsweuse.Whenitcomestothestructuraldesign.First,Ideterminethecolumngridandsingleframe,designandcalculateonthebasisofarchitecturaldesignandtechnicalrequirements.Afterthedesign,Icandeterminethecalculationdiagramandcalculatetheframeload,whichincludesdeadload,liveload.Basedonthat,Icalculatetheinternalforceoftheframe.Ialsomakethecalculationoftheinternalforceonverticalloadbytwobendingmomentdistributionmethod.KeyWords:architecturaldeign;structuraldesign;theinternalforcecalculation武汉科技大学城市学院毕业设计（论文）III目录1.1工程概况............................................................................................11.2设计参考资料....................................................................................11.3地区水文地质资料............................................................................11.4地区地震效应及场地状况................................................................11.5主要材料的选用................................................................................22结构方案与布置..............................................................................32.1结构方案............................................................................................32.2柱网布置及层高................................................................................32.3梁板柱尺寸的确定.............................................................................32.3.1横向框架梁尺寸的确定....................................................................32.3.2纵向连系梁........................................................................................42.3.3板厚....................................................................................................42.3.4框架柱尺寸的确定............................................................................43结构横向框架计算简图..................................................................63.1轴线图.................................................................................................63.2梁、柱线刚度计算.............................................................................63.2.1梁的线刚度........................................................................................63.2.2柱的线刚度........................................................................................64荷载计算..........................................................................................84.1恒荷载计算........................................................................................84.1.1屋面框架梁线荷载计算...................................................................8武汉科技大学城市学院毕业设计（论文）IV4.1.2楼面恒荷载标准值...........................................................................94.1.3屋面框架柱集中力G及偏心弯矩M...........................................104.1.4楼面框架柱集中力G及偏心弯矩M...........................................134.1.5计算榀框架恒荷载分布计算简图.................................................174.2活荷载标准值..................................................................................184.2.1屋面及楼面活荷载取值.................................................................184.2.2屋面及楼面框架活荷载标准值.....................................................184.2.3屋面及楼面框架节点处活荷载集中力标准值（柱顶）............194.2.4屋面及楼面活荷载实际荷载总值RF及跨中弯矩0M..................194.2.5框架活荷载布置计算简图.............................................................214.3风荷载标准值..................................................................................224.3.1地区资料及计算公式.....................................................................224.3.2各层风荷载计算.............................................................................234.4水平地震力标准值..........................................................................234.4.1重力荷载代表值.............................................................................234.4.2结构自振周期1T...............................................................................264.4.3各层地震作用.................................................................................285荷载作用内
