Brace to Column Base Plate Design now Available

You may now design a Brace to Column Base Plate Connection in RISAConnection v8. This connection type combines the original single column base plate with a gusset from a connected vertical brace member. The connection allows tapered or rectangular gussets that frame into either the column flange or web. The location of the workpoint may also be adjusted to match your exact geometry.

The distribution of loading from the brace to the column and base plate is calculated per the AISC Design Guide 29: Vertical Bracing Connections – Analysis and Design section 4.3.

The connection is designed by checking each applicable limit state at each sub-connection interface: the brace to gusset, the gusset to column, and the base plate.

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:…

HSS Tube Moment Connections per CSA S16 now Available

Wide Flange beam to HSS Tube column moment connections can now be designed in RISAConnection version 9 with both the US and Canadian design standards. HSS tubes may be selected as the supporting column member on either of the two moment connections: Column/Beam Direct Weld Moment Connection Column/Beam Flange Plates Moment Connection When either 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 equation in the CIDECT Design Guide 3, Table 7.1. These limit states are all applicable only within a certain range, so RISAConnection checks the applicable ratios in the HSS Limitations check. If this fails, then the connection geometry is outside the “Range of Applicability” from the CIDECT Design Guide 3 Table 71…

Vertical Brace Connections per Canadian Code now Available

RISAConnection Version 8.0 now offers Vertical Brace Diagonal Connections, the Vertical Chevron Brace Connection, and the Knee Brace Connection according to the Canadian (CSA S16-09 or CSA S16-14) design codes. The design of these connections is similar to designs already implemented for the AISC design codes including; load analysis types, limit state checks, Whitmore Section checks and the output report view. To access these connections, select the Canadian S16 design code from the list of available Design Codes on the Solution tab of (Global) Project Settings…
