小高层毕业设计计算书

摘要-І-小高层住宅毕业设计计算书XX本科毕业设计--II摘要本次设计分为建筑与结构设计两部分。本设计主要进行了结构布置、结构选型、一榀框架的完整计算：包括荷载计算、内力计算、内力组合、截面设计及配筋计算。此外，进行了柱下基础、楼梯、现浇板等构件的设计。在一榀框架计算中，着重进行了结构方案中7轴框架的抗震设计。在确定结构布置方案后，先进行了重力荷载代表值的计算,接着利用顶点位移法求出自振周期，进而按底部剪力法计算水平地震作用，采用D值法求解水平荷载作用下的结构内力（弯矩、剪力、轴力），用弯矩二次分配法计算竖向荷载（恒载及活荷载）作用下的结构内力，找出最不利的一组或几组内力组合。在考虑强柱弱梁、强剪弱弯、强节点弱构件的基础上，进行内力调整并进行截面的配筋计算。关键词框架；结构布置；抗震设计；内力组合XX本科毕业设计--IIAbstractThisdesignisdividedintotwoparts:architecturaldesignandstructuredesign.Thepurposeofthedesignarethearrangementofstructure,theselectionofstructuretype,acompletecalculationofonepartoftheframe(includesthecalculationofloadandforce,combinationofforces,designofsectionandcalculationofreinforcement).Besides,therearedesignofcolumnfoundation,stairs,poredconcreteslabandconcreteawningetc.Andinthedesignaboutacompletecalculationofonepartoftheframe,themostimportantistheanti-seismicdesigninthelongitudinalframesofaxis9.Whenthedirectionsoftheframesisdetermined,firstlytheweightofgravitationiscalculated.Thenthevibratecycleiscalculatedbyutilizingthepeak-displacementmethod,thenmakingtheamountofthehorizontalseismicforcecanbegotbywayofthebottom-shearforcemethod.Theseismicforcecanbeassignedaccordingtotheshearingstiffnessoftheframesofthedifferentaxis.Thentheinternalforce(bendingmoment,shearingforceandaxialforce)inthestructureunderthehorizontalloadscanbeeasilycalculated.Afterthedeterminationoftheinternalforceunderthedeadandliveloads,thecombinationofinternalforcecanbemadebyusingtheExcelsoftware,whosepurposeistofindoneorseveralsetsofthemostadverseinternalforceofthewalllimbsandthecoterminousgirders,whichwillbethebasisofprotractingthereinforcingofthecomponents.Keywordsframes;Structurearrangement;Seismicdesign;Thecombinationofinternalforces目录I目录摘要.........................................................................................................................................IIAbstract..................................................................................................................................II1设计资料...............................................................................................................................11.1工程背景...........................................................................................................................11.1.1设计标高.........................................................................................错误!未定义书签。1.1.2墙身做法.........................................................................................................................11.1.3屋面做法.........................................................................................................................11.1.4楼面做法.........................................................................................................................11.1.5楼面荷载.........................................................................................................................11.1.6风荷载.............................................................................................................................11.1.7地基条件.........................................................................................................................11.1.8地震作用.........................................................................................错误!未定义书签。1.1.9耐火等级.........................................................................................................................22结构布置及梁柱截面初估...................................................................................................22.1结构布置...........................................................................................................................22.2梁柱截面尺寸初估...........................................................................................................22.2.1框架梁.............................................................................................................................22.2.2框架柱.............................................................................................................................23荷载计算...............................................................................................................................33.1屋面恒荷载.......................................................................................................................33.2楼面恒载...........................................................................................................................33.3构件自重...........................................................................................错误!未定义书签。3.4墙体自重标准值...............................................................................................................43.4.1外墙.................................................................................................................................43.4.2内墙.................................................................................................................................43.4.4节点集中荷载（以○7轴为例）.......................................................................
