钢结构常见的几种钢结构换算单位:
1、[力的单位 Power unit]:
1 lb = 4.448 N = 453.592 g
1 KN = 0.2248 kips
kips(千磅)
lb(磅)
1 kips = 4.448 KN= 453.592 kg
2、[长度单位 Length unit]:
in.(英寸)
ft.(英尺)
yd.(码)
mi.(英里)
1 in. = 25.4 mm // 1 mm= 0.03937 in.
1 ft. = 0.3048 m=304.8 mm // 1 m = 3.28084 ft.
1 yd. = 3 ft.
3、[分布荷载单位 Distributed load unit]:
1 KN/m = 0.06852kips/ft
1 KN/m<sup>2 =0.02089 kips/ft^2
1 psf = 47.88 N/m^2
psf (lb/ft^2)
1 kips/ft = 14.59KN/m
1 kips/ft<sup>2= 47.88 KN/m^2
4、[一些常量 Some constants]:
钢材E = 29000 kips/in.^2
容重 = 490 lb/ft^2
