Hi,
The CAESAR II has a guide for Modeling Spring Cans with Friction which is used if these spring cans are allowed to slide on their foundation. The Guide says this modeling technique can also be used in situations where shoe or trunnion slides on top of a bolted spring can but it does not mention how.
How should I model it differently for friction between the bottom of pipe shoes(NODE 10) and top of a bolted spring can (For my case, the spring can is bolted down to the foundation and it does not move).
Please help, thanks.
