Ansys-connecting a beam to a base slab
Ansys-connecting a beam to a base slab
(OP)
Hello,
Iam modelling a overhead water tank. The tank has a bottom ring beam all along the circumfrence . This has to be connected to the base slab. for bottom ring beam i have used beam elements and for base slab i have used shell element.also how do i join the base slab with the cylindrical side wall of the tank. could any one tell me the step by step procedure. since iam not much familia with ansys
thanks and regards

I am also not familiar with Ansys but Defining local elements on surface, curves, edges are common in all the FE softwares.
The first thing I believe is to use solid brick elements instead of shell, as the normal thickness of water tank slab is 100-150mm and so it would be nice if you use brick elements so that you can check the stress distribution along the thickness as you have to provide Reinforcement on both outer as well as inner.
For brick elements you need to create a section with thickness of slab and side wall. define 2D(shell) elements on that section and revolve all the shell elemtns to 360 to get solid brick elements, you can defined no. of copies(no of ele)along the perifery while defining it.
still if you want to model it with shell then the first thing you need to do is to define no. of elements on the curve/edge where slab and side wall meets this will model exactly same no. of elements and node location on junction. after that you can merge the duplicate nodes.
Hope this will help you.
