19、建筑面积6521.45m2,占地面积746.92m2。地震设计烈度7度,建筑场地类别为类,场地特征周期为0.35s,基本风压为0.35 kN/m2,基本雪压0.30kN/m2,地面粗糙度为C类。2. 结构方案及布置该建筑为综合办公楼,根据该房屋的使用功能及建筑设计要求建筑平面布置灵活,有较大空间。框架结构的特点是整体性好,满足大空间,耐久性好。而且框架结构占地面积小,可在地面留下较大的空间,以满足绿化,交通,保护既有建筑物等规划要求,造型新颖美观,具有很好的艺术效果,并且建筑采光好,视野开阔。综合考虑以上结构体系的特点,根据本地地形,抗震等级,以及经济方面,本工程选用框架结构形式。该工程采用全
20、现浇结构体系,15层混凝土强度等级为C40,以上各层均为C30,结构平面布置如下图.3. 构件初估3.1 柱截面尺寸的确定利用式A=a, 式中:A为横截面面积,取方形时边长为a;G为结构单位面积的重量,根据经验估算钢筋砼高层建筑约为1218KN/ m,由于框架结构办公楼荷载较小,按15kN/m考虑;n为验算截面以上楼层层数;F为验算柱的负荷面积,可根据柱网尺寸确定;为砼轴心抗压强度设计值;设防烈度7度、大于30m高的框架结构抗震等级为二级,因此柱轴压比限值取0.8;为地震及中、边柱的相关调整系数,7度设防地区,中柱取1,边柱取1.1. 对于中柱,F = 7.2(6.6+2.2)/2 = 31.
21、68 m,1层中柱(n取8;C40混凝土,=19.1MPa); A=a=0.284m, a=0.534m.6层中柱(n取3;C30混凝土,=14.3MPa) A=a=0.142m, a=0.378m.初步选定中柱截面550mm550mm;对于边柱,轴边柱F=7.26.6/2=23.76m,1层(n取8;C40混凝土,=19.1MPa);A=a=0.235m, a=0.485m.6层边柱(n取3;C30混凝土,=14.3MPa) A=a=0.117m, a=0.343m。初步选定边柱截面500mm500mm;轴边柱F=7.2(6.6/2+0.9)=30.24m,1层(n取8;C40混凝土,=19
22、.1MPa);A=a=0.299m, a=0.547m.6层边柱(n取3;C30混凝土,=14.3MPa) A=a=0.150m, a=0.387m.初步选定边柱截面550mm550mm.根据以上结果并综合考虑其他因素,设计柱截面尺寸取值如下:1层 700mm700mm,26层 600mm600mm,78层550mm550mm。3.2 梁尺寸确定梁截面高度hb=(1/121/8)l,l为跨长,边跨l=6600mm,中跨l=2200mm;梁截面宽度bb=(1/31/2)hb. 横向框架跨数少,主梁沿横向布置有利于提高建筑物的横向抗侧刚度,因此本工程框架采用横向承重,根据梁跨度可初步确定横向框架主
23、梁为240mm650mm,次梁为240mm400mm,走道梁及悬挑梁为240mm500mm;纵向连系梁为240mm650mm.3.3 楼板厚度的确定楼板为现浇单向板,一般厚度取(1/401/30)板(短向长度)且不小于80mm,3600/40=90m,取100mm90mm,满足要求.3.4 柱高度底层柱高度h=3.9m+0.45m+0.75m=5.1m ,其中3.9m为底层层高,0.45m为室内外高差,0.75m为基础顶面至室外地面的高度。其他柱高等于层高,即3.6m。4. 重力荷载计算4.1 屋面(顶盖)及楼面的恒荷载标准值屋面(上人)均布荷载标准值:30厚细石混凝土保护层 22kN/m30
