1．屋面层总重力荷载代表值
女儿墙重量：
(1.95+0.51+0.875)×[(11.4+0.2)×2+(25+0.2)×2-
(2.5+0.4×10+0.5×4)]=217.11kN
屋面板重量：
6.4×(4-0.2-0.15)×(11.4-0.2-0.3-0.2)×2=499.90kN
7.7×(6-0.15×2)×(11.4-0.2-0.3-0.2)×2=939.25kN
5.9×[(6-0.2-0.15)×(2.5-0.3)×2+(2.5-0.3)×(3.6-0.3)]
+
6.4×(1.8-0.25)×(2.5-0.3)=211.33kN
499.90+939.25+211.33=1650.48
kN
电梯机房重量：
0.91+2.366+1.333+3.465+1.43+3.887+25×0.3×0.3
×1.5×2+
25×0.2×0.2×(1.8×2+2.5×2)+5.9×1.6×2.3=50.453kN
楼梯间重量：
(7.275+15.132+3.958)×2+(1.275+1.716+0.449+1.6
2)+
(2.61+5.148+1.346+0.486)=67.38kN
4.5×[(2.5-0.4)+(2.5-0.25-0.2)+(5.4-0.3-0.25)+
(5.4-0.3-0.2)]=62.55kN
3.89+4.031+0.432+0.571=8.924
kN
25×3×(0.4×0.4×3+0.5×0.5)=54.75
kN
5.9×(5.4-0.35)×(2.5-0.3)=65.55kN
67.38+62.55+8.924+54.75+65.55=2

kN
8层柱重量：
25×1.5×(0.4×0.4×9+0.5×0.5×5)=100.88kN
17×0.02×1.5×(0.4×4×9+0.5×4×5-0.2×2×14)=9.59
kN
100.88+9.59=110.47
