建筑设计院办公楼设计

本科毕业设计(论文)题目：荭叶建筑设计院办公楼结构设计I摘要本工程占地面积约873平方米左右，建筑面积5238平方米。本建筑为五层，总高度22.8米，室内外高差为0.45米，女儿墙高0.9米。建筑总长度为58.2米，总宽度为15米。本工程结构设计采用多层钢筋混凝土框架结构，基本步骤为：结构计算简图的确定；荷载计算；内力分析；内力组合；梁、柱截面配筋、板的设计、楼梯的设计、基础的设计以及结构施工图的绘制等。其中，内力计算考虑以下四种压力作用，即恒荷载、活荷载、风荷载以及地震作用；柱、板的设计采用弹性理论；梁的设计采用塑性理论；楼梯选用板式楼梯；基础选用十字交叉条形基础。在进行截面抗震设计时，遵循了强剪弱弯，强柱弱梁，强节点弱构件的设计原则，且满足构造要求。本工程结构形式为钢筋混凝土框架结构，设计严格遵守我国现行规范，其中包括«建筑地基基础设计规范»、«建筑结构荷载规范»、«混凝土结构设计规范»、«建筑抗震设计规范»等。计算中包括荷载计算，内力组合，基础设计，楼梯设计等。关键词：办公楼；框架；钢筋混凝土IIAbstractTheprojectcoversanareaofabout873squaremeters,buildingareaof5238squaremeters.Thisbuildingisfivelayers,totalheight22.8meters,theelevationdifferenceofinsideandoutsideof0.45meters,0.9metershighparapet.Buildingatotallengthof58.2meters,atotalwidthof15meters.Theengineeringstructuredesignadoptsmulti-layerreinforcedconcreteframestructure,basicstepsasfollows:thedeterminationofstructurecalculationdiagram;Theloadcalculation;Theinternalforceanalysis;Internalforcecombination;Beamandcolumnsectionreinforcement,theboarddesign,thedesignofstair,basicdesignandstructureoftheconstructiondrawing,etc.Amongthem,theinternalforcecalculation,considerthefollowingfourkindsofloadisconstantloadandliveload,windloadandearthquakeaction;Thedesignofthecolumn,theboardbyusingelastictheory;Beamdesignadoptsthetheoryofplasticity;Stairchoosesplatestair;Selectsthecrossbarbasis.Whenmakingsectionseismicdesign,followingthestrongshearweakbending,strongcolumnweakbeam,strongnodeweakcomponentdesignprinciple,andsatisfiestherequirementofconstruction.Thisengineeringstructureformforreinforcedconcreteframestructure,design,strictlyabidebythecurrentspecificationincludingthe«buildingfoundationdesigncode»,«loadcodeforthedesignofbuildingstructuresreinforcedconcretestructuredesigncode»，buildingseismicdesigncode,etc.Includedintheloadcalculation,internalforcecombination,foundationdesign,stairdesign,etc.Keywords:officebuilding；framework；reinforcedconcreteIII目录绪论..................................................................1第一章建筑设计说明...................................................21.1建筑方案论述..................................................21.1.1设计依据.................................................21.1.2设计内容、建筑面积、标高.................................21.1.3房间构成和布置...........................................21.1.4采光和通风...............................................21.1.5主要立面和出入口的考虑...................................31.1.6防火及安全...............................................31.1.7各部分工程构造...........................................31.1.8本建筑设计的主要特点.....................................4第二章结构布置和计算简图.............................................5第三章荷载计算.......................................................73.1恒载计算......................................................73.1.1屋面框架梁线荷载标准值...................................73.1.2楼面框架梁线荷载标准值...................................73.1.3屋面框架节点集中荷载标准值...............................83.1.4楼面框架节点集中荷载标准值...............................83.2活荷载计算....................................................93.2.1屋面活荷载...............................................93.2.2楼面活荷载...............................................93.3风荷载计算...................................................103.4地震作用计算.................................................113.4.1重力荷载代表值计算......................................113.4.2框架刚度计算............................................123.4.3结构基本周期的计算......................................133.4.4多遇水平地震作用标准值计算..............................143.4.5横向框架弹性变形验算....................................14第四章内力计算......................................................164.1恒荷载作用下的内力计算.......................................16IV4.2活荷载作用下的内力计算.......................................214.3风荷载作用下的内力计算.......................................244.4水平地震作用下的内力分析.....................................26第五章荷载组合及最不利内力确定......................................295.1基本组合公式.................................................295.1.1框架梁内力组合公式......................................295.1.2框架柱内力组合公式......................................305.2梁的内力组合.................................................305.2.1梁端弯矩调幅............................................305.2.2梁控制截面的内力组合....................................315.3框架柱内力组合...............................................385.3.1无地震作用时的组合......................................385.3.2有地震作用效应时的组合..................................395.3.3框架柱组合过程..........................................39第六章框架结构配筋计算..............................................466.1梁的配筋计算.................................................466.1.1边跨梁配筋计算..........................................466.1.2中跨梁配筋计算..........................................476.2框架柱配筋计算...............................................476.2.1框架柱的纵向受力钢筋计算.................................476.2.2斜截面受剪承载力计算....................................49第七章现浇板配筋计算................................................537.1屋面板计算...................................................537.1.1荷载计算................................................537.1.2按弹性理论计算..........................................53
