Modeling reinforced concrete in ABAQUS
Hi everyone,
I am a master student working on my master thesis using ABAQUS. I am modeling an experiment, but the problem is that my results from ABAQUS do not agree with the experimental results. Can you help me to check if I have done any mistakes?
The model is a slender square concrete column 150x150mm and 1300mm long.
Longitudinal reinforcement: 550MPa, diamater 8mm
Lateral reinforcement: yield strength 630MPa, diamater 6.5mm, spacing 10.5mm
Mean compressive strength of concrete: 34.32 MPa
Eccentricities of applied load: ex=50mm ey=50mm
Load: 1kN/s
Pinned conditions at both sides
I use concrete plasticity damage model. For defining the load I use deformation control with a prescribed deformation 0.010m.
I have attached my input file and the expected load-deflection curve.
Thank you for your help!

Hi there!
Hi there!
Can you please specify in detail what kind of problem you are facing?
Cheers!

Hi Naseef!
Hi Naseef!
I had problem with the units and I fixed it. I have also changed the Amplitude to Smooth Step and did other changes to the model as well. But still I don't get correct result. In the experiment the maximum load reached is 900 kN. However I only reach 90 kN before failure.
What is the reason I reach failure so early?
Thanks!
