六层框架结构图书馆毕业设计

【内容摘要】：本设计主要进行了结构方案中横向框架③轴框架的抗震设计。在确定框架布局之后，先进行了层间荷载代表值的计算，接着利用顶点位移法求出自震周期，进而按底部剪力法计算水平地震荷载作用下大小，进而求出在水平荷载作用下结构内力（弯矩、剪力、轴力）。接着计算竖向荷载（恒载、活荷载以及雪荷载）作用下的结构内力，结合EXCEL软件进行验算，并找出最不利的一组或几组内力组合。选取最安全的结果计算配筋并绘图。此外还进行了结构方案中的室内楼梯的设计（完成了平台板、梯段板、平台梁等构件的内力和配筋计算及施工图绘制）、楼盖的设计（完成了板的配筋和梁的配筋）、基础的设计等。【关键词】：框架结构结构计算抗震设计【Abstract】:Thepurposeofthedesignistodotheanti-seismicdesigninthelongitudinalframesofaxis③.Whenthedirectionsoftheframesisdetermined,firstlytheweightofeachflooriscalculated.Thenthevibratecycleiscalculatedbyutilizingthepeak-displacementmethod,thenmakingtheamountofthehorizontalseismicforcecanbegotbywayofthebottom-shearforcemethod.Thenseismicforcecanbeassignedaccordingtotheshearingstiffnessoftheframesofthedifferentaxis.Thentheinternalforce(bendingmoment,shearingforce,axialforce&snowforce)inthestructureunderthehorizontalloadscanbeeasilycalculated.Afterthedeterminationoftheinternalforceunderthedeadandliveloads,thecombinationofinternalforcecanbemadebyusingtheExcelsoftware,whosepurposeistofindoneorseveralsetsofthemostadverseinternalforceofthewalllimbsandthecoterminousgirders,whichwillbethebasisofprotractingthereinforcingdrawingsofthecomponents.Thedesignofthestairsisalsobeapproachedbycalculatingtheinternalforceandreinforcingsuchcomponentsaslandingslab,stepboardandlandinggirderwhoseshopdrawingsarecompleted.Thedesignoffloorslab,foundationand“#”-floorslabisalsobecompletedintheend.【Keywords】:framesstructures,structuraldesign,anti-seismicdesign.某省某市某大学工程学院毕业设计1目录1.中英文内容摘要.....................................................................12.设计任务书.........................................................................12.1工程概况.........................................................................12.2地质、水文及气象资料..............................................................12.3施工技术条件及建筑材料供应........................................................12.4设计内容及要求....................................................................12.4.1建筑设计部分................................................................12.4.2结构设计部分................................................................23.前言.................................................................................34.工程概况............................................................................44.1工程概况.........................................................................44.2柱网布置.........................................................................44.3框架结构承重方案的选择............................................................44.4框架结构的计算简图................................................................54.5初估梁柱截面尺寸..................................................................64.5.1梁截面尺寸初选..............................................................64.5.2柱截面尺寸初选..............................................................65.框架侧移刚度的计算..............................................................75.1横梁线刚度bi的计算...............................................................85.2纵梁线刚度bi的计算...............................................................85.3柱线刚度ci的计算.................................................................85.4各层横向侧移刚度计算（D值法）....................................................86.重力荷载代表值的计算...........................................................106.1楼屋面永久荷载标准值.............................................................106.2屋面及楼面可变荷载标准值.........................................................116.3墙、门、窗重力荷载计算...........................................................116.4梁、柱计算.......................................................................116.4.1梁柱平面布置图.............................................................116.4.2梁、柱重力荷载计算.........................................................116.5各质点重力荷载代表值计算.........................................................137.横向水平荷载作用下框架结构的内力和侧移计算..............................187.1横向自振周期的计算...............................................................187.2水平地震作用及楼层地震剪力的计算.................................................197.3多遇水平地震作用下的位移验算.....................................................207.4水平地震作用下框架内力计算.......................................................218.竖向荷载作用下框架结构的内力计算...........................................268.1计算单元确定.....................................................................268.2荷载计算........................................................................268.2.1恒载作用...................................................................268.2.2活载作用...................................................................288.3内力计算........................................................................299.横向框架内力组合................................................................369.1结构抗震等级.....................................................................36某省某市某大学工程学院毕业设计29.2框架梁内力组合...................................................................369.2.1框架梁内力组合.............................................................379.2.2柱端弯矩设计值及调整.......................................................4310.截面设计............
