1、多层综合楼结构计算一 .设计资料(1) .设计标高:室内设计标高0.000,室内外高差450。(2) .墙身做法:外墙墙身240,为普通机制砖填充墙。墙面用M5混合砂浆砌筑,1:3水泥砂浆底,贴瓷砖墙面,25。内隔墙墙身200,墙面为水刷石墙面(包括混合砂浆打底),25。正立面2-7层为玻璃幕墙,100厚。一层为落地玻璃窗。(3) .楼面做法:水磨石地面,10面层,20水泥砂浆打底。110钢筋混凝土板,15厚天棚水泥砂浆抹灰,吊顶棚。(4) .屋面做法: 80泡沫混凝土保温层(2%自两侧向中间找坡),20厚1:3水泥砂浆找平层,二毡三油防水层上撒绿豆砂保护,热沥青一度隔气层。110厚钢筋混凝土

2、板,15厚天棚水泥砂浆抹灰,吊顶棚。(5) .门窗做法:门厅,酒吧,商场门为铝合金门,其余为木门。窗为钢组合窗。(6) .地质资料:(属II类场地,余略)(7) .地震烈度:7度。(8) .活荷载:走廊2.0KN/,楼梯间2.0KN/,厕所2.0KN/,办公室2.0KN/,门厅2.0KN/,商场3.5KN/,库房6.0KN/. (9) .恒荷载:玻璃幕墙1.0-1.5KN/,填充墙19KN/m3,钢筋混凝土25KN/m3,水刷石墙面0.5KN/,贴瓷砖墙面0.5KN/,水泥砂浆20KN/m3,木门0.2KN/,钢组合窗0.4-0.45KN/,铝合金门0.4KN/.电梯机房7KN/.水磨石地面0

3、.65KN/.一 结构布置.该建筑为多层综合写字楼,一层为商场,酒吧间,2-7层为出租写字间,建筑平面布置灵活,有较大空间,可考虑采用框架结构。楼层为7层,主体高度为23.60米。该工程采用全现浇结构体系. 结构平面布置图见下: 因现浇框架钢筋混凝土结构受温度变化影响,温度缝最大间距55m,在8-D轴设伸缩缝。所以取轴号1-8,A-D框架简化计算。在1-8轴线横向方向布置主梁,A-D纵向方向布置连系梁。在1-8轴线间布置次梁。三 .构件初估。1柱截面初估由于框架办公楼荷载较小,按13kN/计算;负荷面积按F= 7.2×(2.7+6.6)/2 = 33.48考虑,取1。设防烈度为7度,

4、小于60m高的框架结构抗震等级为三级,因此取0.8A = a2 = × = = 0.29 a = 0.54 m 初步估计柱的尺寸的为600×600。为计算简便,边柱中柱尺寸取相同。2梁尺寸确定。 该工程定为纵横向承重,主要为横向承重,根据梁尺寸初步确定:主梁高h : (1/81/12)L = 550-825 取 h = 600 宽b : (1/31/2)h = 200-300 取 b=250连系梁高h : (1/10-1/15)L = 480-720 取h =500 宽b : (1/3-1/2)h = 167-250 取 b =250次梁高h : (1/12-1/18)L

5、= 367-550 取 h = 500 宽b : (1/3-1/2)h = 167250 取 b =200 3初选楼板。楼板为现浇双向连续板,t (1/50)L =72 . 取 t = 110. 四结构计算简图及梁柱刚度计算(取一榀横向框架计算)。 假定框架柱嵌固于基础顶面上,框架梁与柱刚接。由于各层柱的截面尺寸不变,故梁跨等于柱截面形心轴线之间的距离。底层柱高从基础顶面算至二楼楼面,基础标高根据地质条件,室内外高差等定为-1.00m,二楼楼面标高+4.80m,故底层柱高为5.80m.其余各层柱高从楼面算至上一层楼面(即层高)。故均为3.00m.多层框架考虑为纵横向承重,主要为横向承重,为超静

6、定结构,故在内力计算前,应预先估算梁,柱的截面尺寸及结构所采用的材料强度等级,以求得框架中各杆的线刚度。混凝土强度等级: 梁用C20 (Ec = 25.5 × 106 kN/) 柱用C30 (Ec = 29.5 × 106 kN/) 结构计算简图如下: 1. 梁的线刚度计算:主梁:I0 =4.5×10m全现浇框架梁: a. 中框架梁 Ib= 2.0I0= 9.0×10m b. 边框架梁 Ib= 1.5I0=6.75×10m边框架梁(b=0.25m.h=0.6m):跨度为6.6m时,kb = = = 2.6×10kN·m跨度为

7、2.7m时,kb =6.4×10kN·m中框架梁(b=0.25m,h=0.6m):跨度为6.6米时, kb = =3.5×10kN·m跨度为2.7米时, kb = = 8.5×10kN·m2柱的线刚度计算(b=0.6m,h=0.6m) 第一层:柱高5.8m ,Ic=1.08×10m kc=5.5×10 第二七层:柱高3.0m,Ic=1.08×10mkc=10.62×103.柱的侧移刚度计算 见下图表。 对于高度小于50m,且高宽比h/b=23.6/60.6=0.39<4的建筑物,仅考虑梁柱
