Rise of three-hinged Parabolic Arch Solution

STEP 0: Pre-Calculation Summary

Formula Used

Rise of arch = (Ordinate of Point on Arch*(Span of Arch^2))/(4*Horizontal Distance from Support*(Span of Arch-Horizontal Distance from Support))
f = (y_Arch*(l^2))/(4*x_Arch*(l-x_Arch))
This formula uses 4 Variables

Variables Used

Rise of arch - (Measured in Meter) - The Rise of arch is the vertical distance from the centerline to the arch’s crown. It is the highest point on the arch from the reference line.
Ordinate of Point on Arch - (Measured in Meter) - Ordinate of Point on Arch is the ordinate of any point along the central line of the arch. It basically gives the Equation for a three-hinged Parabolic arch.
Span of Arch - (Measured in Meter) - Span of Arch is the horizontal distance between the two supporting members of an arch.
Horizontal Distance from Support - (Measured in Meter) - Horizontal Distance from Support represents the horizontal distance from any support of the arch to the section being considered.

STEP 1: Convert Input(s) to Base Unit

Ordinate of Point on Arch: 1.4 Meter --> 1.4 Meter No Conversion Required
Span of Arch: 16 Meter --> 16 Meter No Conversion Required
Horizontal Distance from Support: 2 Meter --> 2 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f = (y_Arch*(l^2))/(4*x_Arch*(l-x_Arch)) --> (1.4*(16^2))/(4*2*(16-2))

Evaluating ... ...

f = 3.2

STEP 3: Convert Result to Output's Unit

3.2 Meter --> No Conversion Required

FINAL ANSWER

3.2 Meter <-- Rise of arch

What is a Three-Hinged Arch?

A three-hinged arch is a geometrically stable and statically determinate structure. It consists of two curved members connected by an internal hinge at the crown and is supported by two hinges at its base. Sometimes, a tie is provided at the support level or at an elevated position in the arch to increase the stability of the structure.

What makes Arches different from Other Structures?

One of the main distinguishing features of an arch is the development of horizontal thrusts at the supports as well as the vertical reactions, even in the absence of a horizontal load. The internal forces at any section of an arch include axial compression, shearing force, and bending moment.
