Settling Length given Pressure Drop Solution

STEP 0: Pre-Calculation Summary

Formula Used

Settling Length = Prestress Drop/(2*Simplified Term*Prestressing force after Immediate Losses)
l_set = Δf_p/(2*η*P)
This formula uses 4 Variables

Variables Used

Settling Length - (Measured in Meter) - Settling Length is the length where the effect of anchorage friction is absent.
Prestress Drop - (Measured in Pascal) - Prestress Drop is the drop in applied prestress force due to strain in tendons.
Simplified Term - Simplified Term here represents the value which is equal to (μa+kx)/x.
Prestressing force after Immediate Losses - (Measured in Newton) - Prestressing force after Immediate Losses is force after immediate losses. It is also called as reduced value of prestressing force after elastic shortening, anchorage slip and loss due to friction.

STEP 1: Convert Input(s) to Base Unit

Prestress Drop: 10 Megapascal --> 10000000 Pascal (Check conversion here)
Simplified Term: 6 --> No Conversion Required
Prestressing force after Immediate Losses: 20.01 Kilonewton --> 20010 Newton (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

l_set = Δf_p/(2*η*P) --> 10000000/(2*6*20010)

Evaluating ... ...

< 10+ Force Variation Diagram and Loss Due to Anchorage Slip Calculators

Settling Length given Prestressing Force Immediately after Loss

Go Settling Length = sqrt(Slip of Anchorage*Steel Area in Prestress*Modulus of Elasticity of Steel Reinforcement/(Prestressing force after Immediate Losses*Simplified Term))

Prestressing Force after Immediate Loss when Reverse Friction Effect is Considered

Go Prestressing force after Immediate Losses = (Prestress Force at a Distance/(exp(Simplified Term*Distance from Left End)))+Prestress Drop

Prestressing Force at distance x when Reverse Friction is Considered

Go Prestress Force at a Distance = (Prestressing force after Immediate Losses-Prestress Drop)*exp(Simplified Term*Distance from Left End)

Pressure Drop when Anchorage Slip and Settling Length are Considered

Go Prestress Drop = (Slip of Anchorage*Steel Area in Prestress*Modulus of Elasticity of Steel Reinforcement)/(Settling Length*0.5)

Area of Prestressing Steel given Settling Length

Go Steel Area in Prestress = 0.5*Prestress Drop*Settling Length/(Slip of Anchorage*Modulus of Elasticity of Steel Reinforcement)

Anchorage Slip given Settling Length

Go Slip of Anchorage = 0.5*Prestress Drop*Settling Length/(Steel Area in Prestress*Modulus of Elasticity of Steel Reinforcement)

Loss of Prestress due to Slip

Go Prestressing Force = Tendon Area*(Modulus of Elasticity of Steel Reinforcement*Slip of Anchorage)/Cable Length

Slip of Anchorage

Go Slip of Anchorage = Prestressing Force*Cable Length/(Tendon Area*Modulus of Elasticity of Steel Reinforcement)

Settling Length given Pressure Drop

Go Settling Length = Prestress Drop/(2*Simplified Term*Prestressing force after Immediate Losses)

Pressure Drop given Setting Length

Go Prestress Drop = 2*Prestressing force after Immediate Losses*Simplified Term*Settling Length

Settling Length given Pressure Drop Formula

Settling Length = Prestress Drop/(2*Simplified Term*Prestressing force after Immediate Losses)
l_set = Δf_p/(2*η*P)

What is Settling Length?

Due to the setting of the anchorage block, as the tendon shortens, there is a reverse
friction. Hence, the effect of anchorage slip is present up to a certain length. This length is referred as settling length (lset). Beyond settling length, the effect is absent.

How to Calculate Settling Length given Pressure Drop?

Settling Length given Pressure Drop calculator uses Settling Length = Prestress Drop/(2*Simplified Term*Prestressing force after Immediate Losses) to calculate the Settling Length, The Settling Length given Pressure Drop is defined as the equation to find out length of beam from which effect of anchorage slip is absent. Settling Length is denoted by l_set symbol.

How to calculate Settling Length given Pressure Drop using this online calculator? To use this online calculator for Settling Length given Pressure Drop, enter Prestress Drop (Δf_p), Simplified Term (η) & Prestressing force after Immediate Losses (P) and hit the calculate button.
