Considering shear lag effects in T-shaped non-planar RC wall

Post by shhosseinzadeh »

Hi everyone,

I was wondering if there is a modelling approach that I can take the impact of shear-lag into account by using Beam-Column element.
Usually modelling RC walls with the Beam-Column element will not capture the shear lag effect. I found a research done by Jonathan David Waugh on T-Shaped walls but they didn`t really elaborate their modelling approach to consider shear lag effect.

I would be grateful if someone can help me address this issue,

Regards,

You cannot capture such phenomenon using beam-column elements. You can read the works of D. E. Lehman, L. N. Lowes and J. Pugh on modelling these shear wall elements.

The only option that I am aware that you can consider is to use shell elements. There is this multi-layered shell element (MITC4) developed by Xinzheng Lu. However, I tried using it in the past and it has major problems.

Dear Omer,

Thanks for your reply. I will definitely take a look into the papers you have suggested. in the meantime, I was wondering if other types of elements (i.e. MVLEM and/or SFI-MVLEM) is capable of simulating such phenomenon. do you have any idea?

I forgot to ask. can you please tell me the exact title of the paper by D. E. Lehman, L. N. Lowes and J. Pugh? I couldn't find the one with non-planar walls.

Thanks
