第一章建筑设计1.1工程概况本工程为济南市怡和花苑3#住宅楼设计,工程位于山东省章丘市,建筑面积约4200平方米。采用现浇混凝土框架结构,室内设计标高±0.000,室内外高差为0.45米。1.2设计资料1、工程地质条件:承载力特征值280kpa;属于I类场地,设计地震分组为第二组。地震烈度为6度。2、自然气候条件:(1):基本风压为0.3KN/㎡(2):基本雪压为0.3KN/㎡1.3设计思想住宅楼是我们长期居住生活的地方,各个房间的功能明确,而且,能满足我们日常生活的需要,卧室、客厅、厨房、卫生间、书房。客厅宽大明亮,采光好的位置,卧室阳光充足。框架结构能满足住宅楼的交错纵横的墙体,能灵活的区分各个房间,所以,该设计采用现浇框架体系。1.4建筑设计说明1.4.1平面设计本设计一共四个单元,两种户型,每户型约100m,每户设有卫生间、客1
厅、书房厨房、卧室、阳台、餐厅,满足住户的日常生活。图1-1底层平面图考虑到主体建筑的平面布置和结构形式,应为今后发展、改造和灵活分隔创造条件。本工程设计为长方形,长约70米,宽15米。1.4.2立面设计图1-2济南怡和花园正立面图建筑物在满足使用要求的同时,它的体型、立面以及内外空间的组合,还会给人们在视觉和精神上的某种感受。因此,我们在进行建筑设计时,尤其是在进行建筑物各部分的组合时,还必须注重其体型和立面的美观。【1】1.4.3剖面设计确定房间的剖面形状和比例关系,确定房屋的层数和各部分的标高,研究竖向空间的处理,将平面、立面和剖面密切结合。为了防止室外雨水流入室内,防止建筑因为不均匀沉降使地面降低,为了满足建筑使用的要求,取室内外高差为450mm。45
图1-3剖面图1.5构造做法1.5.1楼面做法30mm厚水泥砂浆面层,10mm厚石灰抹灰,120mm厚钢筋混凝土板。1.5.2屋面做法40mm厚C20细石混凝土,SBS改性沥青,20mm厚1:2水泥砂浆找平层,40mm厚水泥石灰焦渣砂浆2%找平,80mm厚矿渣水泥,120mm厚现浇钢筋混凝土板,10mm厚混合砂浆抹灰。1.5.3卫生间做法120mm厚现浇混凝土板,20mm厚1:3水泥砂浆打底,专用聚合物面砖胶凝剂,10mm防滑地砖。45
1.5.4基础在建筑工程上,把建筑物与土壤直接接触的部分称为基础。它承受着建筑物的上部荷载,并将这些荷载传给地基。根据本设计的地质情况和设计的等级要求,该工程采用钢筋混凝土柱下独立浅基础。【2】第二章结构设计2.1结构选型及计算简图该结构选取8轴线作为内力计算的一榀框架如图2-1所示图2-1一榀框架图2.1.1截面的初步估算45
1.框架梁截面的初步估计框架梁截面高度(其中L=3900),截面宽度故框架梁的,取框架梁的高度为,则梁的截面宽度,取框架梁的宽度为。框架梁的截面2.框架柱截面的初步估算边柱的负载面积小于中柱的负载面积,故使中柱的截面尺寸符合设计要求,那么,边柱的截面尺寸也符合要求。结构的荷载设计值为,底层中柱的轴力设计值为公式(2-1)故取框架柱的截面尺寸为3.板的截面的初步估算取板的厚度为2.1.2计算简图1、框架柱的线刚度计算该工程采用现浇钢筋混凝土结构,对于中框架梁,使用,。室内为高差-0.45m,基础顶面至室外地坪为-0.55,底层柱的计算高度线刚度的计算公式公式(2-2)HF跨梁45

=0.5×14.3×400×400/(467.81×)=2.45>1.0,取=1.0。因为/=3.6/0.6=6<15,所以。=1+[1/(1400×310.02/565)]×(3300/600)×1.0×1.0=1.04偏心距:=1.04×310.02+600/2-35=576.06mm=576.06-565+35=46.06mm=467.81×10/1.0×14.3×600×565=0.064<,故为大偏压。=260.71××94.92/300(360-40)=462.55mm又因为最小配筋率,s,=s,`=0.2%×400×400=320mm,每侧实配416(=804mm)。(4).垂直于弯矩作用平面的受压承载力验算/=2.8/0.4=7,查得=1.05。则轴心构件受压承载力设计值:0.9()=0.9×1.0×(14.3×600×600+300×804)=4987.83kN>N=588.66kN,满足要求。(5)斜截面受剪承载力计算第一层,最不利内力组合:=-35.07kN.m=467.81kN=-14.25kN=0.25×1.0×14.3×400×360=514.8>=14.25,满足要求。因为剪跨比=3.8/(2×0.36)=5.28>3所以取。=1.75/(3+1)×1.43×400×360=91.34>80
,故该层柱应按构造配置箍筋。柱端加密区长度(/6,500mm,),取500。箍筋选用:由第一层,查得柱箍筋加密区的箍筋最小配筋特征值0.07,同时对于四级框架柱,其箍筋加密区范围内的体积配箍率尚且不应小于0.4%,则最小体积配箍率:=0.07×14.3/300=0.715%0.4%=(400-2×40)/[4×(400-2×40)]=0.576取10,78.565,3/>1.35则<174mm。根据构造要求,柱端箍筋最大间距为(8,150),取100mm。取加密区箍筋为四肢10@100。非加密区还应满足<15=150mm,故箍筋取四肢10@200。2.8楼板设计1.设计荷载恒载标准值:3.78,活载标准值:2.02.截面设计混凝土强度等级为C30;板内受力纵筋为HRB335。计算跨度确定:内跨:支承中心线间距离边跨:取(1.025+b/2)与(+)两者中的较小值其中:为梁板边跨的净跨长,b为第一内支座的支承宽度,h为板厚。、分别为班的短跨与长跨的计算长度。3.计算跨度的求解80
