Updated HSS Tube Connection Design According to CSA S16-14/09
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:
