ITERATION ERROR

[MR_12355438]

While performing iteration for neutral axis calculation for Doubly Reinforced Concrete beam, I suffered an error.

Kindly help me ASAP.

Thank you

Hi

Added a line to the stress strain table that means the linterp correctly defines the limits.

Removed the duplicate stress strain calculation.

Renamed the compressive and tension linterp functions by adding c and t to the names

thank you.

For the iteration, you have put extra line for upper limit for strain.

But for the lower limit of strain when it is less than 0.00144, stress varies as 'E' times strains. E = modulus of elasticity. I have put it in the red box.

The remaining I have updated as you have suggested.

How to solve, kindly suggest.

Kindly find the attachment.

thank you.

Hi,

The first two lines of the stress strain table when linearly interpreted get a straight line fit from 0 to 0.00144 it does not need to be done twice.

Thank you very much.
