RISAConnection v11 now incorporates expanded support for HSS tube shapes in Canadian (CSA S16) connection design. The newly supported connections include the following:
Shear Tab connection with HSS column
Clip Angle (One Side) connection with HSS column
HSS to HSS connection
Vertical Diagonal Brace connection with HSS column
Vertical Chevron Brace connection with HSS beam
Knee Brace connection with HSS column or HSS beam

To enable these checks, first select the Canadian CSA S16-14 or CSA S16-09 design code from the list of available Design Codes on the Solution tab of (Global) Project Settings:
