Variation of Eccentricity on Tendon A Solution

STEP 0: Pre-Calculation Summary

Formula Used

Eccentricity Variation of Tendon A = Eccentricity at End for A+(4*Change in Eccentricity at A*Distance from Left End/Length of Beam in Prestress)*(1-(Distance from Left End/Length of Beam in Prestress))
E_A(x) = e_A1+(4*Δe_A*x/L)*(1-(x/L))
This formula uses 5 Variables

Variables Used

Eccentricity Variation of Tendon A - (Measured in Meter) - Eccentricity Variation of Tendon A is the variation considered when the parabolic tendons are used for prestressing of a beam.

Change in Eccentricity at A - (Measured in Meter) - Change in Eccentricity at A is the value for eccentricity considering the end and mid span of parabolic tendon. Here, the value above is for tendon A.
Distance from Left End - (Measured in Meter) - Distance from Left End is the distance considered from the left jacking end on a prestressed member.
Length of Beam in Prestress - (Measured in Meter) - Length of Beam in Prestress is the center to center distance between the supports or the effective length of the beam.

STEP 1: Convert Input(s) to Base Unit

Eccentricity at End for A: 10.02 Millimeter --> 0.01002 Meter (Check conversion here)
Change in Eccentricity at A: 10 Millimeter --> 0.01 Meter (Check conversion here)
Distance from Left End: 10.1 Millimeter --> 0.0101 Meter (Check conversion here)
Length of Beam in Prestress: 10.2 Meter --> 10.2 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

E_A(x) = e_A1+(4*Δe_A*x/L)*(1-(x/L)) --> 0.01002+(4*0.01*0.0101/10.2)*(1-(0.0101/10.2))

Evaluating ... ...

E_A(x) = 0.0100595686236063

STEP 3: Convert Result to Output's Unit

0.0100595686236063 Meter -->10.0595686236063 Millimeter (Check conversion here)

FINAL ANSWER

10.0595686236063 ≈ 10.05957 Millimeter <-- Eccentricity Variation of Tendon A

Distinguish between Concentric and Eccentric Prestressing?

The concentric or axial prestressing members in which the entire cross section of concrete has a uniform compressive prestress. In this type the centroid of the tendon coincides
with that of the concrete section. Where as in eccentric prestressing is a section at which the tendons are eccentric to the centroid, resulting in a triangular or trapezoidal compressive stress distribution.
