Angle between Crown and Abutments given Thrust at Abutments of Arch Dam Solution

STEP 0: Pre-Calculation Summary

Formula Used

Theta = acos((Thrust from Water-Radial Pressure*Radius to Center Line of Arch)/(-Radial Pressure*Radius to Center Line of Arch+Thrust of Abutments))
θ = acos((P-P_v*r)/(-P_v*r+F))
This formula uses 2 Functions, 5 Variables

Functions Used

cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)
acos - The inverse cosine function, is the inverse function of the cosine function. It is the function that takes a ratio as an input and returns the angle whose cosine is equal to that ratio., acos(Number)

Variables Used

Theta - (Measured in Radian) - Theta is an angle that can be defined as the figure formed by two rays meeting at a common endpoint.
Thrust from Water - (Measured in Newton per Meter) - Thrust from water retained behind a wall is the force applied by the water on unit length of wall.
Radial Pressure - (Measured in Pascal per Square Meter) - Radial pressure is a pressure towards or away from the central axis of a component.
Radius to Center Line of Arch - (Measured in Meter) - Radius to Center Line of Arch is a radial line from the focus to any point of a curve.
Thrust of Abutments - (Measured in Newton) - Thrust of Abutments refers to the horizontal force exerted by an arch, vault, or similar structure against its supporting abutments.

STEP 1: Convert Input(s) to Base Unit

Thrust from Water: 16 Kilonewton per Meter --> 16000 Newton per Meter (Check conversion here)
Radial Pressure: 21.7 Kilopascal per Square Meter --> 21700 Pascal per Square Meter (Check conversion here)
Radius to Center Line of Arch: 5.5 Meter --> 5.5 Meter No Conversion Required
Thrust of Abutments: 63.55 Newton --> 63.55 Newton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

θ = acos((P-P_v*r)/(-P_v*r+F)) --> acos((16000-21700*5.5)/(-21700*5.5+63.55))

Evaluating ... ...

θ = 0.522845407666328

STEP 3: Convert Result to Output's Unit

0.522845407666328 Radian -->29.9568351970832 Degree (Check conversion here)

FINAL ANSWER

29.9568351970832 ≈ 29.95684 Degree <-- Theta

What is Arch Dam ?

An arch dam is a concrete dam that is curved upstream in plan. The arch dam is designed so that the force of the water against it, known as hydrostatic pressure, presses against the arch, causing the arch to straighten slightly and strengthening the structure as it pushes into its foundation or abutments.
