Prestress in Tendon given Bearing Stress Solution

STEP 0: Pre-Calculation Summary

Formula Used

Prestressing Force = Bearing Stress*Punching Area
F = f_br*A_pun
This formula uses 3 Variables

Variables Used

Prestressing Force - (Measured in Newton) - Prestressing Force is the force internally applied to the prestressed concrete section.
Bearing Stress - (Measured in Pascal) - Bearing Stress is described as the contact pressure between the separate bodies.
Punching Area - (Measured in Square Meter) - Punching area can be described as the defined as the space occupied by a flat shape or the surface of an object.

STEP 1: Convert Input(s) to Base Unit

Bearing Stress: 50 Newton per Square Millimeter --> 50000000 Pascal (Check conversion here)
Punching Area: 0.008 Square Meter --> 0.008 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F = f_br*A_pun --> 50000000*0.008

Evaluating ... ...

F = 400000

STEP 3: Convert Result to Output's Unit

400000 Newton -->400 Kilonewton (Check conversion here)

FINAL ANSWER

400 Kilonewton <-- Prestressing Force

(Calculation completed in 00.020 seconds)

What is meant by Bearing Stress?

The Bearing Stress (fbr) in the Local Zone is the contact pressure between the separate bodies it differs from compressive stress as it is an internal stress caused by a load. The bearing stress is the force that pushes a structure divided by the area. We can define it as a contact pressure between two separate bodies. If we apply a compressive stress on a body, then there will be a reaction as internal stress in the material of the body. This internal stress is known as the bearing stress.

What is the difference between Normal Stress and Bearing Stress?

Normal Stress - A normal stress is a stress that occurs when a member is loaded by an axial force. The value of the normal force for any prismatic section is simply the force divided by the cross sectional area. A normal stress will occur when a member is placed in tension or compression. Examples of members experiencing pure normal forces would include columns, collar ties, etc.

Bearing Stress -
Bearing stress is the contact pressure between the separate bodies. It differs from compressive stress, as it is an internal stress caused by compressive forces.
