Floor, wall and shell elements

Anonymous
Not applicable

Hello all,

 

I was wondering if there is any difference between a floor and a wall element if they are both modelled as shell elements. I mean, I create the floor panels and set the calculation model as shell, same thing for the shear walls. Is there any difference (in the in-plane or out-of-plane stiffness, in the integration rule, in the shell element used,etc.)?

 

Also, I would like more information regarding the default shell element used by Robot - number of nodes, number of degrees of freedom for each node, interpolation functions, integration rule, if a reduced stiffness for the shear component is taken into account, etc.

 

Last question, how is the number of panels in a model influencing the computational burden? I understand the assembly of the stiffness matrix is the most time consuming process, so will reducing the number of panels help making it slightly quicker?

 

Thank you!
