The above calculations were to focus on the crack width in piles only. However, to calculate the Neutral axix for a circular or rectangular columns, you need to iterate until the Summation of all forces = Zero;

Can you please develop an excel sheet to calculate the crack width for circular section under axial tension force (for example circular pile under uplift force or uplift force associated with moment)

Hi, Can anybody tell what is Z in the above sheet and how to calculate it.

hey can you explain from where did you get the Ms what is 0.93 and 1.88

Yes thank very much

Hi @anilbaral and welcome to strukts forum,

The above calculations were to focus on the crack width in piles only. However, to calculate the Neutral axix for a circular or rectangular columns, you need to iterate until the Summation of all forces = Zero;

-0.85*f'c*Ac + Sum(As*fs) + Pu/fi = Zero (Total)

You can use the following spreadsheet for circular columns: http://strukts.com/design-of-rc-circular-columns-as-per-aci318-08

Hope the above answers your question ðŸ™‚

Please explain briefly how the calculation for depth of neutral axis=356.3 &481.2 were calculated.Thank you.

Thank you all, I will give try to this spreadsheets

Thank you @eagle for the spreadsheet

Sorry @teisir I am not good in spreadsheets. Let us better check this spreadsheet posted by @eagle

You can download from this link http://itrnsfr.com/it-download/?eb160de1de89d9058fcb0b968dbbbd68/eb8b2400fb17abe5d0f24b06461f60f7/ENm81

Hi @Teisir, this will take a little time. However, I will try to send you a spreadsheet not prepared by me for small eccentricity crack width check.

Can you please develop an excel sheet to calculate the crack width for circular section under axial tension force (for example circular pile under uplift force or uplift force associated with moment)
