Hi all,

I'm trying to perform a simple analysis using concrete material type but it seams to be impossible. In the results table the maximum and minimum values are ever "Not Available". 

Can someone say me why?

Attached is my sample beam. 

Note that there are two scenarios because I was trying both.

no?

Please, help me!

thanks

Hi masamp,

Here's the error message that appears in your log file:

 ** STOP: Unable to determine concrete material constants (A4,K0)
          from specified concrete strengths
          Check input or specify material constants directly
          Element group number =     1
 ** Error (1)

(You can view the log file from the "Report" environment by selecting "Log" at the bottom of the tree.)

From looking at your material properties, I think the problem is that you do not have anything entered on the "Hardening" tab. Please enter the appropriate data.

Thanks John. 

I tryed input the correct hardening parametrs but the message in log report remains.

I dont know how to evaluate A4 and k0 parameters.

I am attaching my material library.

Do you have a material library that you can send it to me? I would like to do some tests and comparisions with my material parameters.

Thanks again!
