solid shell elements

[joeathens]

hello everybody

I am using sap2000v14.2.0 for the analysis of a simple deep deam, it is possible to use shell element for a 3-d analysis? the programm has an option for shell section type but nothing is mentioned on the manual.

this element will have 8x6 dof on every element?

and why someone will use a 2-d shell instead of 3-d shell analysis? as most of researchers do, since every structure has 3-d and the brick element will give a better simulation of the bevahior.

thanks for you time
joe

I think a thick shell should do for your problem since you are only interested in deep beam behavior.

Bricks and solids are often used to model structures with low aspect ratios in all planes. Deep beam has a "low" aspect ratio in only one plane, the plane of the length and depth.

So why model a deep beam with a 3D element?

The answer to your question could be: What outputs do you need or expect?
