框架结构中学教学楼毕业设计计算书

四川理工学院毕业设计摘要在实际工程中，钢筋混凝土框架结构是一种十分常见的结构形式，广泛应用于各种公共建筑，如学校、商场、写字楼、住宅楼等。本设计对多层框架学生公寓楼的框架进行了设计。在进行设计时先对结构的恒载、活载、风荷载以及地震荷载进行计算。利用分层法、D值法分别得到竖向荷载和水平荷载作用下结构各构件的内力标准值。然后按照最不利组合方式，对各种荷载作用下的内力进行组合。最后在组合中找出各构件最不利的一组或几组对构件进行截面设计，选取较安全的结果进行配筋。通过本次毕业设计使我了解了框架结构设计的整个过程，达到了从理论到实践的飞跃。同时通过设计中对建筑规范和软件的使用，使我能够更好地应用规范和操作软件，提高了自身的能力，也为以后的工作打下了基础。关键字：框架结构；荷载；分层法；D值法四川理工学院毕业设计AbstractInpracticalengineering,thereinforcedconcreteframestructurehasbeenacommonstructuralformowingtotheirsuccessfulapplicationsinmanyareassuchasresidence,office,schoolsandotherpublicbuildings.Thisthesisisaimedatthedesignfortransverseframeofteachingbuildingswithmultistoryframe.First,deadloads,liveloads,windloadandseismicloadofthestructurearecomputedreferringto“LoadStandards”.Thenthestandardvaluesofeachmembersofstructureunderhorizontalloadandverticalloadcanbeobtainedbyusingstratificationmethodand“D”methodrespectively.Next,theinternalforcesundervariousloadarecombinedaccordingtothemostunfavorablecombinationmode.Finally,themostunfavorableoneorseveralonesintheabovecombinationstorealizesectiondesignformembersisfound.Inthisway,thesafestresultstoreinforceischosenandWorkingDrawingisPainted.thebasement,thefloorandthestairsarealsodesignedandstructuralworkingdrawingarepaintedinthisthesis.Moreover,thestructurecomputerizationisshownviaemployingPKPM.Thankstothisgraduationdesign,andcombiningwithknowledgeI’velearnedinthepastfouryears,Imastertheentireprocessofthedesignforframestructure,andrealizetheleapfromtheorytopractice.Meanwhile,Ibecomemorefamiliarwiththestandardsandoperationsofrelativesoftwaresthanbefore.Allthesehavebuiltagoodfoundationformyfuturework.Keywords:framestructure;load;stratification;“D”method四川理工学院毕业设计目录前言..............................................................1第一部分建筑设计...................................................21.1建设项目名称及概况.............................................21.2建筑地点.......................................................21.3设计资料.......................................................21.4建筑要求.......................................................2第二部分：结构设计..................................................32.1柱网布置.......................................................32.2主要构件材料及尺寸估算.........................................32.2.1主要构件材料...............................................32.2.2主要构件的截面尺寸.........................................32.3框架结构计算简图和结构平面布置图...............................4第三部分楼板设计...................................................53.1屋面和楼面板的荷载计算.........................................53.2楼板计算.......................................................63.2.1标准层楼板计算.............................................73.2.2屋面板计算.................................................9第四部分次梁计算..................................................114.1荷载计算......................................................114.2次梁计算......................................................114.2.1弯矩计算..................................................114.2.2剪力计算..................................................124.3.截面设计......................................................12第五部分竖向荷载作用下框架结构的内力计算..........................145.1横向框架计算单元..............................................145.2梁、柱线刚度计算..............................................145.3.恒载荷载计算..................................................155.3.1线荷载....................................................155.3.2集中荷载..................................................165.3.3集中荷载引起的偏心弯矩M...................................18四川理工学院毕业设计5.3.4屋面层梁上作用的恒载......................................195.3.5楼面层梁上作用的恒载......................................205.4恒载内力计算..................................................205.5活载荷载计算..................................................275.5.1线荷载....................................................275.5.2集中荷载..................................................275.5.3集中荷载引起的偏心弯矩M...................................284.5.4屋面层梁上作用的活载......................................295.5.5楼面层梁上作用的活载......................................305.6活载内力计算..................................................305.7竖向荷载作用下梁、柱内力计算..................................37第六部分横向荷载作用下框架结构的内力计算..........................436.1风荷载作用楼层剪力的计算......................................436.2梁、柱线刚度计算..............................................436.3框架柱的侧移刚度D值计算......................................436.4风荷载作用下的位移验算及内力计算..............................456.5水平地震作用下的内力计算......................................486.5.1各层柱、梁、板重力荷载....................................486.5.2.各层墙自重标准值计算......................................496.5.3各层（各质点）自重标准值计算..............................516.6重力荷载代表值计算............................................516.7等效总重力荷载代表值计算......................................516.8等效总重力荷载代表值计算......................................516.9横向自振周期计算..............................................526.9.1结构顶点的假想侧移计算....................................526.10水平地震作用及楼层地震剪力的计算.............................536.11水平地震作用下的位移验算.....................................556.12水平地震作用下框架内力计
