Prestressing Force after Immediate Loss given Initial Prestress Solution

STEP 0: Pre-Calculation Summary

Formula Used

Prestressing Force after Loss = Initial Prestress Force*Pre-Tensioned Area of Concrete/Transformed Section Area of Prestress
P_o = P_i*A_{Pre tension}/A_Pretension
This formula uses 4 Variables

Variables Used

Prestressing Force after Loss - (Measured in Kilonewton) - Prestressing Force after Loss is the prestressing force after immediate losses. It is the reduced value of prestressing force after elastic shortening, anchorage slip and loss due to friction.
Initial Prestress Force - (Measured in Kilonewton) - Initial Prestress Force is the force which is applied to the tendons by the jack.
Pre-Tensioned Area of Concrete - (Measured in Square Millimeter) - Pre-Tensioned Area of Concrete is a construction method where steel tendons are stressed before pouring concrete, enhancing structural strength.
Transformed Section Area of Prestress - (Measured in Square Millimeter) - Transformed Section Area of Prestress is the area of the member when steel is substituted by an equivalent area of concrete.

STEP 1: Convert Input(s) to Base Unit

Initial Prestress Force: 435 Kilonewton --> 435 Kilonewton No Conversion Required
Pre-Tensioned Area of Concrete: 12 Square Millimeter --> 12 Square Millimeter No Conversion Required
Transformed Section Area of Prestress: 0.025 Square Millimeter --> 0.025 Square Millimeter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_o = P_i*A_{Pre tension}/A_Pretension --> 435*12/0.025

Evaluating ... ...

P_o = 208800

What are the stages of Loading in Prestressing process?

Stages of Loading The analysis of prestressed members can be different for the different stages of loading. The stages of loading are as follows.
1) Initial : It can be subdivided into two stages. a) During tensioning of steel b) At transfer of prestress to concrete.
2) Intermediate : This includes the loads during transportation of the prestressed members. 3) Final : It can be subdivided into two stages. a) At service, during operation. b) At ultimate, during extreme events.
