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

When any of the above connections are designed per the Canadian design codes (CSA S16-09 or CSA S16-14), the HSS limit state checks are done per the appropriate sections and equations found in CIDECT Design Guides #1 and #3.

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:
