Losses of Pre-stress_I-Beam & T-Beam

Dear Viewers,

Good-Day to everybody. Hope, you all are well. Lets Start today's Lesson.
At my last article I was talking about "Losses of Pre-stress". According to this topic I am going to start my today's article.
Hope already you have read my last article about "Losses of Pre-Stress",

http://seasoft022.blogspot.com/2013/06/losses-of-pre-stress.html

In this article, I described briefly about Losses of Pre-stress, Classification of Losses of Pre-stress, Significance of Losses of Pre-stress and Necessary Formulas for calculating Losses of Pre-stress in case of "Pre-tensioned Pre-stress Beam & Post-tensioned Pre-stress Beam".
I gave two (02) examples also at my previous article about "Estimating the Losses of Pre-stress in case of both Pre-tensioned & Post-tensioned Pre-stress Beam". But those examples regarding about a simple rectangular pre-stress beam.
Now I am going to present to you "Estimating the Losses of Pre-stress in case of Pre-stress I-Beam & T-Beam".

Our necessary formulas are same, please review these necessary formulas again,

Losses of Pre-stressing Force in case of Pre-tensioned Pre-stress beam:

Losses due to Elastic Shortening, Δf_s = nf_c,

Losses due to Creep, Δf_s = (C_c-1)nf_c,

Losses due to Shrinkage, Δf_s = E_sδ_s,

Losses due to Steel Relaxation, Δf_s = 5% of f_i,

Losses of Pre-stressing Force in case of Post-tensioned Pre-stress beam:

Losses due to Elastic Shortening, Δf_s = 0.5nf_c,

Losses due to Creep, Δf_s = (C_c-1)nf_c,

Losses due to Shrinkage, Δf_s = E_sδ_s,

Losses due to Anchor Slip, Δf_s = (Δ_a E_s)/L,

Losses due Friction, Δf_s = (f₂-f₁) = (f_i-f₁),

Losses due to Steel Relaxation, Δf_s = 5% of f_i,
