第一章建筑设计方案1.4建筑方案总体评价现代建筑设计的基本核心是完备的建筑功能、科学的建筑技术和丰富的建筑艺术。根据这三个核心的实在意义分析,即以建筑功能为关键,以建筑技术为特色,以建筑美观为建筑艺术性的直观体现。本建筑设计综合考虑了功能用途、技术措施、经济指标和艺术观感等方面,进行了综合考量和设计。建筑功能方面:该建筑除室内空间的尺寸满足办公楼的使用功能外,还为日常办公创造了良好的环境,具有良好的朝向,以及采光、保温、隔声、隔热、和通风性能。同时,建筑设计充分思考了本体与周围环境的关系,使人与环境的关系协调,提升了工作效率。建筑技术方面:该建筑确定了与土建工程各方面要求相符合的建筑材料、工程做法、结构措施和施工方案。建筑艺术方面:本建筑整体造型为矩型,建筑整体具有规则对称的造型,外墙采用石灰墙简约,符合现代办公楼的设计风格与理念。5第二章结构设计方案5 第二章结构设计方案第二章结构设计方案2.1结构方案及结构布置简图2.1.1结构选型框架结构适用于承受竖向荷载作用、层数较少的建筑,它具有在建筑上能提供较大的空间,它具有平面布置灵活等特点。而框架—剪力墙结构虽具有较强的承载力、较好的延性和整体性且抗震能力好;但剪力墙的存在,在一定程度上限制了建筑平面设计的灵活性,且成本造价不易控制。而本工程共计6层,结构高度21.6m,符合《建筑抗震设计规范GB50011-2010》中关于框架结构在7度区的房屋最大使用高度,故本工程选用钢筋混凝土框架结构较为合理。2.1.2柱网布置本工程为综合楼,柱网布置方式分采用内廊式,即采用两边为办公室,中间为走道的布置方案。2.1.3承重方案虽本工程横向尺寸较短,纵向尺寸较长,横向框架跨数少,但考虑抗震要采用纵横双向框架承重方案,以提高建筑物整体抗侧刚度。2.1.4施工方法本工程采用现浇式钢筋混凝土框架结构,即梁、柱、楼盖均为现浇钢筋混凝土,以保障构件有较好的整体性和抗震性能。2.1.5其他结构构件选型1、雨蓬结构:采用悬挑雨蓬;2、楼梯结构:采用板式楼梯较为经济;3、柱下基础:采用桩基础,承台埋深取2m。2.1.6结构设计简图表2-1梁截面尺寸(mm)及各层混凝土强度等级层次混凝土强度等级横梁(b×h)纵梁(b×h)次梁(b×h)AB跨CD跨BC跨1~6300×600300×500300×600250×50092

第二章结构设计方案2.5内力组合2.5.1结构抗震等级结构抗震等级可根据结构类型,地震烈度,房屋高度等因素,由查表可知,本工程的框架为三级抗震等级。2.5.2框架梁内力组合该框架结构考虑了四种内力组合,即1.2SGk+1.4SQk,1.35SGk+1.0SQk及1.2SGE+1.3SEk。此外,对于本工程,1.2SGk+1.4Swk这种内力组合与考虑地震作用的组合相比一般较小,对结构设计不起控制作用,故不予考虑。各层梁的内力组合结果见表7-5,表中SGk、SQk两列中的梁端弯矩M为经过调幅后的弯矩(条幅系数取0.8)。考虑抗震的正截面承载力抗震调整系数,抗剪计算时=0.85,梁的受弯计算时=0.75;柱的受压计算时取=0.80(轴压比不小于0.15)或取=0.75(轴压比不小于0.15).控制截面:框架柱的弯矩、轴力和剪力沿柱高是线性变化的,取各层柱的上下端截面作为控制截面。框架梁,在水平力和竖向荷载共同作用下,剪力沿梁轴线呈线行变化,弯矩呈抛物线形变化,取梁的两端和梁跨间最大正弯矩的截面为控制截面。92

第二章结构设计方案2.6构件截面设计2.6.1框架梁截面设计1.设计内力(1)梁设计内力的选择梁是选择组合中最大的弯矩与剪力进行截面配筋计算,即利用弯矩设计纵向钢筋,利用剪力设计箍筋,其中最大的弯矩与剪力可以是来自不同组工况的内力,具体设计内力的选择见各个杆件截面设计。(2)柱设计内力的选择柱是偏压构件。大偏压时弯矩愈大愈不利,小偏压时轴力愈大愈不利,弯矩与轴力是耦合的,所以,两者必须来自同一个工况。究竟哪一种工况最危险,需要借组于N-M包络图来判断,必要时还要试算,哪一种配筋量大,哪一组即为设计内力。柱还要组合最大剪力用于设计箍筋,剪力可以取自不同于弯矩和轴力的工况(取最大值)。具体设计内力的选择见各个杆件截面设计。2.梁截面设计(1)设计大致步骤对于中间层边跨梁,考虑到前面内力组合中支座处正弯矩比跨中弯矩要大,首先利用支座处正弯矩设计值,以T形截面来配置梁底纵筋;然后根据跨中正弯矩设计值结合支座处已配梁底纵筋或弯起或截断来确定跨中的梁底纵筋,利用支座负弯矩设计值以双筋矩形截面来配置梁顶纵筋;对于顶层边跨梁,则是跨中正弯矩比支座处正弯矩要大,类似上述步骤只是先确定跨中梁底纵筋,再确定支座处梁底纵筋。纵筋的截断、锚固以构造要求确定。钢筋采用电渣压力焊接长,所以不考虑钢筋的搭接。然后哦按规范有关要求配置抗剪箍筋,验算梁抗剪承载力。对于中跨梁,仍然利用支座正弯矩设计值,以T形截面来配置梁底纵筋,利用支座负弯矩设计值以双筋矩形截面来配置梁顶纵筋,由于跨中是负弯矩且很小,根据支座处已配梁顶架立筋直接作为跨中的梁顶纵筋就可满足其承载力要求,其余操作同边跨梁。设计参数:92

第二章结构设计方案1.荷载计算柱传来的内力是只考虑竖向荷载作用的恒载和荷载。FkA=FkD=1223.34+256.4=1488.74kN,Vk=9.68kN,Mk=14.85FkB=FkC=1600.68+454.67=2055.35kN,Vk=8.39kN,Mk=12.86建筑物基础设计方案:采用泥浆护壁成孔灌注桩,具体设计方案如下:室内外地坪标高-0.45m,自然地面同室外地面时采用直径为500mm的混凝土灌注桩,以粉砂土层为持力层,桩尖伸入持力层3m,设计桩长为12m,初步设计承台高为1.00m,承台埋置深度-2m,桩顶升入承台50mm。2.单桩承载力计算1、单桩竖向极限承载力标准值2、基桩竖向承载力特征值R=Ra=Quk/k=1381.13/2=690.56kN根据上部荷载初步估算桩数为:n=2055.35/690.56=2.98则设计桩数为4根3.桩基竖向承载力验算92 第二章结构设计方案根据《建筑桩基技术规范》(GJG94-2008),当按单桩承载力特征值进行计算时,荷载应标准组合值。由于桩基所处场地的抗震设防烈度为7度(0.10g),且场地内无可液化砂土,因此可以不进行地震效应的承载力验算。根据桩数及承台尺寸构造初步设计矩形承台,取承台边长为2.5与2.5,矩形布桩。桩中心距3d,则s=3*500=1500mm,桩心距承台边缘均为500mm。图2-14中柱承台平面图92 第二章结构设计方案图2-15基础详图承台及其上填土的总重为:Gk=2.5×2.5×2.5×20=312.5kN偏心竖向力作用:满足要求,故初步设计是合理的。4.承台设计根据上面的桩基设计和构造要求,承台尺寸,高度,混凝土选用C30混凝土,,,钢筋HRB400,。1)承台内力计算92 第二章结构设计方案2)承台厚度及受冲切承载力验算为防止承台产生冲切破坏,承台应具有一定厚度,承台厚度为1000mm,,则h0=1000-60=940mm分别对柱边冲切和角桩冲切进行验算,以验算承台厚度的合理性。由于桩基为圆形,换算为方柱:(1)柱对承台冲切承台受柱冲切的承载力应满足下式:,则冲跨比:,。冲切系数:。,满足冲切要求。(2)角柱冲切验算承台受角柱冲切的承载力应满足下式:,。冲切系数:。92 第二章结构设计方案,满足冲切要求。(3).承台受剪承载力计算剪切系数:;,满足抗剪切要求。(4).承台受弯承载力计算取基桩净反力最大值进行计算,则xi=0.5m因此,选用1216,As=2413.2mm2,延平行Y轴方向均匀布置。因为该承台为正方形,故延X轴配筋与Y相同。5.承台与承台梁构造设计混凝土桩顶伸入承台50mm,承台间通过承台梁连接。承台梁顶面标高为-1.5m,与承台顶齐平,根据构造要求,梁宽250,梁高400,梁内主筋上下共412通长配筋,箍筋采用8@200,承台底做100mm厚C10素混凝土垫层,垫层挑出承台边缘100mm。5桩身结构设计混凝土选用C30,钢筋HRB400取稳定系数。92 第二章结构设计方案>Nmax故桩身轴向承载力满足要求。6.桩身构造设计桩身按构造要求配筋,选用812的HRB400级钢筋通长配筋,箍筋选用6的HPB335级钢筋,间距200mm。7.估算A,D轴线柱下桩数,设计A、D轴线桩基础的方法与B轴线下相同,单桩极限承载力标准值为1488.74kN,桩基竖向承载力特征值为690.56kN,A、D轴柱下荷载标准组合值为FK=1488.74kN,M=14.85,V=9.68.则A、D轴下设计桩数为4根。根据估算的桩数和承台构造要求,设计A、D轴线承台平面尺寸时为2.5m2.5m,与B轴相同,桩中心距取1.5m,桩心与承台边缘间距为0.5m。92
