Column structural analysis optimization

Hello,

First, I have to say that I am new to structural analysis and would appreciate your point of view on the definition I am working on.

I am trying to compare two types of columns: one is a solid concrete cylinder, and the other is a wired/triangulated column. Both are subjected to compression with a 1m² slab on top, bearing a uniform load. My goal is to assess the performance of each column in order to make a comparison.

I have managed to get the analysis to work, but the results seem strange. The wired column, which uses less material, appears to have a lower utilization rate than the solid concrete column.

Is my approach correct, or am I doing something wrong that might be affecting the accuracy of my results?

Your help would be greatly appreciated!

Hi, your thicknesses for the different cross sections are not assigned properly. If you want to analyse a solid circular section you need to set the thickness to be the radius. Otherwise both columns have the same cross section thickness, therefore the single column performs worse.

Hello,

I have one more question, I would like to know the min and the maximum force in MPa apply to element of each column. I 'am read that the beam force componant can give the compression or traction in N[kN] than I can traduce in MPa.


From what I see, the wired column (blie) get less compression than the green one. Is that correct ? or I am still missing something ?

Thank you very much for your help

This is correct, you have one element vs 210 elements so it is expected your forces to be lower in the model with more elements
