Thrust given Intrados Stresses on Arch Dam Solution

STEP 0: Pre-Calculation Summary

Formula Used

Thrust of Abutments = Intrados Stresses*Base Thickness-6*Moment acting on Arch Dam/Base Thickness
F = S*T_b-6*M_t/T_b
This formula uses 4 Variables

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.
Intrados Stresses - (Measured in Pascal) - Intrados Stresses is defined as the stresses on the inner wall of the Arch Dam.
Base Thickness - (Measured in Meter) - Base Thickness is the maximum thickness or width of a dam measured horizontally between upstream and downstream faces and normal to the axis or centerline crest of the dam.
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.

STEP 1: Convert Input(s) to Base Unit

Intrados Stresses: 250 Newton per Square Meter --> 250 Pascal (Check conversion here)
Base Thickness: 1.3 Meter --> 1.3 Meter No Conversion Required
Moment acting on Arch Dam: 54.5 Newton Meter --> 54.5 Joule (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F = S*T_b-6*M_t/T_b --> 250*1.3-6*54.5/1.3

Evaluating ... ...

F = 73.4615384615385

STEP 3: Convert Result to Output's Unit

73.4615384615385 Newton --> No Conversion Required

FINAL ANSWER

73.4615384615385 ≈ 73.46154 Newton <-- Thrust of Abutments

What is an 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.

How to Calculate Thrust given Intrados Stresses on Arch Dam?

Thrust given Intrados Stresses on Arch Dam calculator uses Thrust of Abutments = Intrados Stresses*Base Thickness-6*Moment acting on Arch Dam/Base Thickness to calculate the Thrust of Abutments, Thrust given Intrados Stresses on Arch Dam is defined as pressure exerted on inner wall of dam. Thrust of Abutments is denoted by F symbol.

How to calculate Thrust given Intrados Stresses on Arch Dam using this online calculator? To use this online calculator for Thrust given Intrados Stresses on Arch Dam, enter Intrados Stresses (S), Base Thickness (T_b) & Moment acting on Arch Dam (M_t) and hit the calculate button. Here is how the Thrust given Intrados Stresses on Arch Dam calculation can be explained with given input values -> 73.46154 = 250*1.3-6*54.5/1.3.
