Hi
Thanks for posting this project. I would like to help you by performing calculations to EN 15269-11-2018. I am very familiar with European standards as I use them routinely in my work. For this particular code, I am aware of the requirements and know how to perform the required calculations for extrapolating fire curtain dimensions.
Once you hire me, I will purpose to perform various calculations using either Mathcad or Excel. The calculations will include limiting stress as per clause B.2, barrel calculations as per clause B.3, barrel support calculations as per clause B.4, axle calculations as per clause B.5, endplate calculations, Shrinking of the material, Bottom bar expansion allowance and maximum length of the various sections among others. Once I perform these calculations, I will be able to come up with the right dimensions that meet the code requirements.
I would like you to get the best possible work that is not only thorough but also based on sound engineering principles. That is what I propose to offer.
I welcome you to chat with me regarding your project and any other issue you might have. I look forward to hearing from you.
Kind Regards
Simon.
