What is Pre-Tensioned Concrete Section?
Pre-Tensioned Concrete is a variant of prestressed concrete where the tendons are tensioned prior to the concrete being cast. The concrete bonds to the tendons as it cures, following which the end-anchoring of the tendons is released, and the tendon tension forces are transferred to the concrete as compression by static friction. Pre-tensioned concrete is most commonly used for the fabrication of structural beams, floor slabs, hollow-core planks, balconies, lintels, driven piles, water tanks and concrete pipes.
How to Calculate Compressive Stress due to External Moment?
Compressive Stress due to External Moment calculator uses Bending Stress in Section = Bending Moment in Prestress*(Distance from Centroidal Axis/Moment of Inertia of Section) to calculate the Bending Stress in Section, The Compressive Stress due to External Moment is defined when the concrete section is subjected to an external moment M due to load or weight on beam. Bending Stress in Section is denoted by f symbol.
How to calculate Compressive Stress due to External Moment using this online calculator? To use this online calculator for Compressive Stress due to External Moment, enter Bending Moment in Prestress (Mb), Distance from Centroidal Axis (y) & Moment of Inertia of Section (Ia) and hit the calculate button. Here is how the Compressive Stress due to External Moment calculation can be explained with given input values -> 0.000167 = 4000*(0.03/7.2E-07).
