Duplication of Pucher Chart Using Finite Element

[Yochael1996]

Hi everyone,

I am trying to get the influence surface of a slab, which should be exactly the same as the Pucher chart. For example, I want to use the FEA to get the following influence surface. Can anyone suggest how to accomplish this?

Regards,
Yochael

Here is an old article on influence surfaces (prior to 1957?) for interest readers, and collectors. Link

Hi Retired13,

Thanks so much for replying!
Yes I read the thread you attached, but it is not exactly the same as what I asked.
Briefly going thru the article you attached, I found it may be helpful. I will review it again in detail later on.
Thank you again!

Regards,

Hi Retired13,

I do found the article very helpful in the sense that it provides a closed-form solution for an influence surface so that I can use it to validate my model.
Thanks again!

Glad that something is working for you. Have fun, and save the old article to help others.

you don't need that. use modern fea software instead.

Hi university_professor,

I understood that FEM is much more practical, but I am doing a project investigating the computation methods of the moment effects on slabs. That's why I referred to the Pucher Chart and I do want to understand what's the theory behind it.
Thank you for replying!
