Hi everyone, I have a problem when simulating the Behavior of Concrete Columns under Axial Compression as follows: I used 2D 2-nodes column with the forceBeamColumn type to model the columns made by high strength concrete (90-100 MPa) and high strength reinforcement bars (785 MPa). However, I got th...

Dear everyone, I am trying to use Bond_SP01 material for my simulation but I dont know where I have made a mistake. This code works very well without ZerolengthSection, but when I modified to add ZeroLengthSection Element, it doesn't run. Does anyone take a look and check for me? Thank you very much...

Thank you very much!

Hello everyone, I want to model the behavior of Steel Fiber Reinforced Concrete (SFRC) that has more ductility than normal concrete. So that, the descending part of the stress - strain curve of SFRC should go down gradually than the normal one. But I tried all the concrete class available in OpenSee...

Dear all,
I want to model a concrete material that contains an amount of steel fibers inside but I don't know what kind of material in OpenSees could be used for this.
Does anyone know how to do this in OpenSees? Please give me some suggestions. Thank you very much!

Dear Vesna,
I used the element type "bbarBrick" with block3D to model this beam. So that at the loading point, I don't know how to create an element to use the command -eleLoad.

Does anyone know the answer for my question? Please help me, I really need your help.

Hello everyone! I want to model a 3D beam as the figure below, but I don't know how to apply a uniform load along y-direction like that. Does any one know how to do that? Please help me. Thank you very much in advance! Sorry for the inconvenience, but this forum doesn't provide BBCode. Please click ...

Dear andy0071,
I have some troubles in my research like what you have here. I wonder that could I have your tcl file for this problem ?
If it's ok, could you send to me through email :ductuandhxd@gmail.com
I will deeply appreciate it. Thank you in advance!

Hi Mohammadf,
Thank you very much for keeping your time on my issue. Could you tell in more detail for me, please?
In my problem, I want to model FRP material as an elastic-brittle material, it has 2 kind of modulus, that are, longitudinal and transverse.
So how can I do that?

Dear all,
My thesis relates to FRP material but I still don't know how to model this material in OpenSees.
Does anyone know how to do it? Please help me to solve this problem.
Thank you very much in advance!
