loads on each concrete are scaled from the reduced load line according to the
various conditions of loading. The area between the two verticals over each concrete
is measured with all necessary accuracy by multiplying the horizontal width
between the verticals by the scaled length of the perpendicular which is midway
between the verticals. The weight of the concrete itself may be computed as
accurately as necessary, by multiplying the radial thickness by the length
between the joints as measured on the curve lying half-way between the intrados
and the extrados. For
example, the load for full loading of the concrete arch which is over concrete No.
1, is measured as follows: The width between the perpendiculars is 2.0 feet;
the height measured on the middle vertical is 4.05 feet; the area is therefore
8.10 feet, which, multiplied by 160, equals 1,296 pounds, which is the load on
this concrete for every foot of width of the concrete arch parallel with the
axis. The radial thickness of concrete No. 1 is 1.90 feet, and the length is 2.15
feet; this gives an area of 4.085 feet, which, multiplied by 160, equals 653.6
pounds. The weight of the concrete is therefore almost exactly one-half that of
the live and dead loads above it; therefore the resultant of these two weights
will be almost precisely one-third of the distance between the center of this
stone and the vertical through the center of the loading. By drawing this line,
we have the line of action of the resultant of these two forces, and this value
is the sum of 1,296 and 654, or 1,950 pounds. In order to simplify the figure,
the arrows representing the lines of force of the loading on the concrete and
the weight of the concrete have been omitted from the figure, and only their
resultant is drawn in. It was of course necessary to draw in these forces in
pencil and obtain the position of the resultant, as explained in Fig. 221; and
then, for simplicity, only the resultant was inked in. The loads on the other concrete
are computed similarly. For more complicated jobs do not count corners twice,
as there is a liability of doing, on concrete walls; for instance. If you are
building a trough, 12 ft. long, 6 ft. wide with concrete walls 6 in. thick and
48 in. high, the two long concrete walls will be 12 ft. long, 4 ft. high and 6
in. thick, but the two other concrete walls will be. only 5 ft. long, 4 ft.
high and 6 in. thick,—because the 6 in. thickness comes off the end of each of
the short concrete walls at each end. Multiply
the area by the thickness in feet or fractions of feet thereof, and you have
the number of cubic feet in the slab. If this slab is 6 in. thick, the number
of cubic feet in it will be 38%x2 or 19%. If you are building a circular tank,
figure the total contents as if it were solid right through; then calculate the
contents of the hollow space that is not to be filled with concrete and
subtract this from the first total. We Are Your Local
