Re: Trapezoidal footing length = 2m , B=1.7m D=0.5m and d- 0.15m. Can anybody help and calculate quantity of concrete by explaining all formulas involved.
# 1
Volume = ((D+d)/2)*B*L
= ((0.5+0.15)/2)*1.7*2
= 0.325*1.7*2
= 1.105 cubic meter

Input is insufficient.size of the column is missing.
If size of the column is 300 x 300 mm, then the volume will
be
= 2x1.7x0.15 + (0.5-0.15)/3 x ((0.3x0.3+2.0x1.7+sqrt
((0.3x0.3)(2.0x1.7))
=0.981 m^3

# 3
Top Length = L1
Bottom Length = L2
Depth = D

Then simple formula is
(L1+L2)/2=L
(B1+B2)/2=B
The Quantity of Concrete is = L * B * D

# 4
suppose area at bottom A1 = (AxB) and area at top A2 (axb), where A,B,a,b are the respective lengths of footing top and bottom. further D is total depth and d is small depth of footing

formula is A1xd + (D-d)x(A1+A2 + sqroot {(A1xA2)/3}

# 5
h(=D-d)\3 * A1+A2+SqrtA1A2 = Q1
A1*A2*thickness = Q2

Q = Q1 + Q2.

# 6
Before calculating the quantity of concrete required for size of pillar or size of footing at (D=0.5 m)

Formula :- L X B X d + D-d/3 x A1 + A2 + &#8730;(A1 X A2)

# 7
Formula for trapezoidal footing quantity
Q = h/3{(a+b)+&#8730;ab}, a&b is area of bottom and top portion
=0.5/3{2x1.7+0.15x0.15+&#8730;3.4x0.0225}
=0.583 Cu.m.

# 8
Q1=2.1*1.7*0.5
Q2=(0.5-0.15)/3*((A1+A2)+(SQRT A1*A2))
A1=Area of bottom portion
A2=Area of top portion
TOTAL QTY=Q1+Q2

# 10
Input is insufficient.size of the column is missing.
If size of the column is 300 x 300 mm, then the volume will be
=h/3(A1+A2+Sq root of A1square+A2square)
=((.5-.15)/3)(.09+3.4+(sq root of(.09 square + 3.4 square)))
=.116(3.49+(sq root of (11.5681))
=.116(3.49+3.401)
=.116*6.891
=.799 cum
