Thrust at Crown of Arch Dam given Moment at Abutments Solution

STEP 0: Pre-Calculation Summary

Formula Used

Thrust of Abutments = Moment acting on Arch Dam/(Radius to Center Line of Arch*(sin(Theta)/(Theta-(cos(Theta)))))+Normal Radial Pressure*Radius to Center Line of Arch
F = M_t/(r*(sin(θ)/(θ-(cos(θ)))))+p*r
This formula uses 2 Functions, 5 Variables

Functions Used

sin - Sine is a trigonometric function that describes the ratio of the length of the opposite side of a right triangle to the length of the hypotenuse., sin(Angle)
cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)

Variables Used

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.
Moment acting on Arch Dam - (Measured in Joule) - Moment acting on Arch Dam is an overturning effect (tends to bend or turn the member) created by the force(load) acting on a structural member.
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.
Theta - (Measured in Radian) - Theta is an angle that can be defined as the figure formed by two rays meeting at a common endpoint.
Normal Radial Pressure - Normal Radial Pressure at the center line is the extrados pressure times the ratio of the upstream radius to the center-line radius.

STEP 1: Convert Input(s) to Base Unit

Moment acting on Arch Dam: 54.5 Newton Meter --> 54.5 Joule (Check conversion here)
Radius to Center Line of Arch: 5.5 Meter --> 5.5 Meter No Conversion Required
Theta: 30 Degree --> 0.5235987755982 Radian (Check conversion here)
Normal Radial Pressure: 8 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F = M_t/(r*(sin(θ)/(θ-(cos(θ)))))+p*r --> 54.5/(5.5*(sin(0.5235987755982)/(0.5235987755982-(cos(0.5235987755982)))))+8*5.5

Evaluating ... ...

F = 37.2137268232182

STEP 3: Convert Result to Output's Unit

37.2137268232182 Newton --> No Conversion Required

FINAL ANSWER

37.2137268232182 ≈ 37.21373 Newton <-- Thrust of Abutments

What are Abutments ?

An abutment is the substructure at the ends of a bridge span or dam supporting its superstructure. Single-span bridges have abutments at each end which provide vertical and lateral support for the span, as well as acting as retaining walls to resist lateral movement of the earthen fill of the bridge approach.
