Venkatesh Yadav Palagala

Dear Mohammed A. Abdulrahman ,

Can you send that paper? Do you have that excel sheet with you?

Yes,

I need to calculate the confined concrete properties for my Beam Section and Column Section and I have to input that data in my Opensees Model.

I have the data for unconfined concrete

Can you provide some formula for calculating those?

Beam subjected to bending, and column subjected to both axial and bending.

Say for example there is manders model. In that way I too had to find those and input them in my Opensees model

Thank you for your time.

Can you help me with that what you have told above. Can you provide some information regarding the same as you mentioned above. Relations etc..?

Thank you very much

Yes sure, I will

Haider Sakban

Hi Venkatesh

In attached spreadsheet, you can find Modified-Kent Park formula and Saatcioglu and Razvi formula. Hopefully, this can help you in your work.

Good luck!

Hi Haider,

Thanks for sharing your excel sheet. Even I had done one excel sheet as such with the help given by Mohammed A. Abdulrahman in the above replies.

By your excel sheet I got to know that you are working on Opensees? Is it?

Yes! Iam working on Opensees.

Can I have your help if I get stuck in Opensees from you.

Am working on RC frames

Yourself?

Yes for sure. I am working on shear walls.

I hope this file will be useful. The modified kent and park model aggrees weel with the opnesees model

Recep Talha Cosar

Hi, I saw your question during my research. I need that kind of Excel table. If you find it. Could you share with me ?
