Hi All, The model is a shell element resting on four vertical springs. A static analysis is desired. but the results are not true for ENT and linear springs The exact solution is: # ---------------------------------------- # Exact Results (Displacement, m): # 1: -1.627 # 2: -4.879 # 3: -1.627 # 4: 1...

Hi,
Unfortunately, the formulation of SHELLMITC4 is for tin plates and does not consider the effects of shear deformation.
I checked both MITC4 and DKGQ. DKGQ is very accurate for the tin plate but there are some errors when the thickness becomes considerable for example, in Mat foundations.

sorry!!
But I need shell forces to design the foundation.
the solid element forces are not appropriate for the design.

many thanks!!

Hi Dear Selimgunay,
I use SHELLDKGQ element for shallow foundation analysis but this element does not consider the shear deformation effects of "thick plates".

is there any shell element in OpenSees considering the shear deformation effects of thick plates?

Thank you!

Hi
I hope this is the last question.
the results are for the natural frame. how can I transform the results to physical frame (x, y).
Thanks a lot.

Thank you for your reply.
would you please tell me a reference for extrapolating.
Thank you!

I model one element shell model with Shell DKGQ element. - The element has 4 nodes (1 2 3 4). - The nodes 1 and 4 are fixed. - A point load is applied to nodes 2 and 3 equal to 100 N. - Shell thickness is equal to 0.02 m. - Modulus of Elasticity is equal to 2.e011 N/m2. - Poison's Ratio is equal to ...
