July 16, 2018 at 11:52 ampeteroznewmanSubscriber
Start by learning how to create a RCC beam in ANSYS with the proper material properties that will provide the softening behavior that will deliver an ultimate load point in the load-deflection curve.
Here is a good discussion on concrete models.
Here is a post with links to three discussions on SOLID65.
July 16, 2018 at 12:12 pmnaik_shrihariSubscriberLoad Vs Deflection curve is linear. Where have I gone wrong?
Could you please tell me what do you mean by softening behavior?
July 16, 2018 at 1:41 pmSandeep MedikondaAnsys Employee
Softening behavior refers to the damage that occurs in the stress-strain behavior of a concrete material. Please go through this article for some additional description.
Now, when you have this behavior included you would see a load vs deflection as discussed in this paper, which helps you determine the ultimate load vs deflection.
Hope this helps.

July 16, 2018 at 4:28 pmnaik_shrihariSubscriberHi Peter
Could you please explain what does tbdata 1,0.3,1,0.304,4.278 mean in the list of commands mentioned in one of those links that you shared ?

TB = table and is used to send a table of values to a material model. The specific meaning of the values after TB depend on the preceding command.
July 16, 2018 at 4:54 pmnaik_shrihariSubscriberThank you Peter. I have now understood the meaning of tb. But those values aren't still clear to me. What do those values (1,0.3 and so on) represent?
July 16, 2018 at 6:18 pmSandeep MedikondaAnsys Employee
These values correspond to what is in the TB command. So depending on that, the TBDATA would point to different material parameters such as poisons ratio, yield stress etc. Now in your case, it looks like 1 corresponds to the first data point and 0.3 to the poisson's ratio. Checkout this part of the manual for understanding material data tables.
