Tapered Wide Flange Connections

Several connections (listed below) can be designed for tapered wide flange members as well as for prismatic wide flanges. RISA-3D requires that the connection occurs at the ends of the members (no mid span connections). This is because RISAConnection imports the section as a prismatic (non tapered) section with the cross-sectional dimensions equal to those of the selected end of the tapered member in RISA-3D.

Available Tapered WF Member Connections

• Beam members in the Beam Shear Tab Splice Connection
• Column members in the Column Shear Tab Splice Connection
• Column and Beam in the Column/Beam Clip Angle Shear Connection
• Column and Beam in the Column/Beam End Plate Shear Connection
• Column and Beam in the Column/Beam Shear Tab Shear Connection
• Beam member only in the Girder/Beam Clip Angle Shear Connection
• Beam member only in the Girder/Beam End Plate Shear Connection
• Beam member only in the Girder/Beam Shear Tab Shear Connection
• Beam members in the Beam Direct Weld Moment Splice Connection
• Beam members in the Beam Extended End Plate Moment Splice Connection
• Beam members in the Beam Moment Plate Moment Splice Connection
• Column members in the Column Direct Weld Moment Splice Connection
• Column members in the Column Extended End Plate Moment Splice Connection
• Column members in the Column Moment Plate Moment Splice Connection
• Column and Beam in the Column/Beam Direct Weld Moment Connection
• Column and Beam in the Column/Beam End Plate Moment Connection
• Column and Beam in the Column/Beam Flange Plate Moment Connection

Limitations

• Currently this is limited to just doubly-symmetric tapered members (flanges must be equal). In the future, we plan on also allowing singly-symmetric tapered WF sections with unequal flanges.
• Tapered WF connections are only considered if they occur at the member ends. (For example, connections applied to beams who are supported by girders or columns along their mid span are not designed).
• A custom Tapered WF shape must be entered and saved permanently to the shape database through RISA-3D, before it can be accessed for use in RISAConnection.
