I'm working on a design for an internal raftering support system for a 120ft diameter API-650 tank. I'm looking at a lateral bracing design for the rafters - I've reviewed some of our old projects, and we've always provided lateral bracing to internal raftering systems by welding 1/4" flat bar...
I'm trying to model a silo with a hopper (shell elements) resting against the ground (solid elements) using Inventor Nastran. In my current model, the ground has significantly lower stiffness than the hopper base and there is a separation contact defined between them. There is also various...
Hello,
I'm looking for a method to model the effect of a soft ground below the base of a steel hopper-bottom silo. I have the silo modeled in Inventor Nastran. As I understand, creating a CAD model for the ground and using contacts isn't an appropriate way to do this because of the large...
