EXAMPLE |
| |
|
|
|
|
| 1.
Determine Longitudinal Bar Weight |
|
|
|
|
| |
|
|
|
|
|
| |
Weight = area
of steel (sq.in.) x number of wires x length (ft.) x 3.4 |
|
|
| |
|
|
|
|
|
| |
WeightL = C x [ ( F/A ) + 1] x I x 3.4 lbs / ft-in2 |
|
|
|
WeightL = 0.147in2 x [ ( 72in / 4in ) +
1] x 20.167 ft x 3.4 lbs / ft-in2 |
| |
|
|
|
|
| |
Note: I is in feet. |
|
|
|
WeightL = 191.51 lbs |
|
|
| |
|
|
|
|
| 2.
Determine Cross Bar Weight |
|
|
|
|
| |
|
|
|
|
|
|
|
|
| |
Weight = area
of steel (sq.in.) x number of wires x length (ft.) x 3.4 |
|
|
|
|
| |
|
|
|
|
|
|
|
|
| |
WeightC = D x [ ( (I - J -
K)/B ) + 1] x [(F+G+H)/12] x 3.4 lbs / ft-in2 |
|
WeightC = 0.205 in2 x [ ( ( 242in - 8in -
18in ) / 8in ) + 1] |
| |
|
|
|
x [( 72in +
4in + 21in ) / 12] x 3.4 lbs / ft-in2 |
| |
Note: I is in inches. |
|
|
|
WeightC = 157.75 lbs |
|
|
| |
|
|
|
|
| 3.
Determine Sheet Weight |
|
|
|
|
| |
|
|
|
|
| |
Weigth per sheet = WeightL + WeightC |
|
|
|
Weigth per sheet = 191.51 lbs + 157.75 lbs |
|
| |
|
|
|
|
| |
|
|
|
Weigth per
sheet = 349.26 lbs |
|
|
| 4.
Determine Sheet Area (ft2) |
|
|
|
|
| |
|
|
|
|
| |
Sheet Area (ft2) = I x [( F + G + H ) / 12] |
|
|
|
Sheet Area (ft2) = 20.167 ft x [( 72 in + 4in + 21in ) / 12] |
|
| |
|
|
|
|
| |
Note: I is in feet. |
|
|
|
Sheet Area =
163.01 (ft2) |
|
|
| |
|
|
|
|
| 5.
Weight per 100 Square Feet |
|
|
|
|
| |
|
|
|
|
| |
Weight per 100
sq. ft. = (Weight per sheet x 100 ) / Sheet Area |
|
Weight per csf = (349.26 lbs x 100 ) / 163.01
(ft2) |
|
| |
|
|
|
|
| |
|
|
|
Weight per
csf = 214.25 lbs / cfs |
