There are few limit states involved in this connection, but the ones that are applicable are time consuming to do by hand. RISAConnection provides a detailed output for each limit state:
For HSS to HSS connections, this T-Connection is just the beginning. RISA is already working on many variants of HSS to HSS connection types, with the intention of adding the full catalog into RISAConnection, making truss design simple.
