ANSWER:
The procedure to calculate the Trapezoidal Load for EH load case at the bottom of the footing is as follows.
The Dimensions of the Abutment is shown in the attached screen shot.
Abutment Length L = 40 ft
Height of Stem wall = 19 ft
Height of Back Wall = 3 ft
Footing thickness = 3 ft
Total Height H = 19 + 3 + 3 = 25 ft .
Ka = 0.3
Gamma = 0.120 ksf
Load at the Bottom of the Footing = Ka x Gamma x H x L
Load at the Bottom of the Footing = 0.3 x 0.120 x 25 x 40 = 36 klf.
