I recommend you to test the ColumnBase software. It's integrated 3D finite element software for modeling, analysis and design of column base plate connections.
Demo version of it is available for free download via: https://pceesoft.com/download
here is the introduction article in LinkedIn: https://www.linkedin.com/pulse/introduction-columnbase-software-amir-hasanpour/
You can model the column, stiffeners, anchor bolts, plate, concrete footing and even grout! and design the connection parts according to design codes automatically.
