Shear Splices between Slabs

In RISAFoundation v8, you can add a shear splice between slabs so that it acts like a hinge. This is useful for modeling the effects of shear keys or dowel joints between slabs.

Two-Sided Shear Connection Design now Available

Now available in RISAConnection v8: the ability to design a Two-Sided Shear Connection. Building from our existing one-sided shear connection (for column/beam & girder/beam), this connection now offers the user a powerful tool to provide clip angles to both sides of the column or girder web. By designing the two-sided shear connection, designers can make changes to the bolt layouts on each side of the web & modify left and right clip angle vertical position per your project needs. Similar to how bearing on column or girder web is considered for the one-side clip angle connection, the bearing checks on the column or girder web will then take into account the load from both sides of the column or girder. The user has the freedom to select the column/girder section, beam sections and the angle clips on either side of the web, as well the welds from beam to shear tab. These extensive options can all be found in the Components. Users will also appreciate the option to vertically offset the beams on either side of the connection and design for staggered connection. These customizable options can easily be found in the Assembly input…

Weak Axis Column to Beam Moment Connections now Available

RISAConnection v8 now offers weak axis moment connections with beams framing into the web of a wide flange column. Previously, connections were only permitted to frame into the column flange. This additional feature will allow users to change the orientation of their wide flange column. This option currently applies to beam/column moment connections that use flange plates or direct weld. After selecting one of the connection types above, users will now be able to change the Column Connection Type to “Web” in the Connection Properties. Column/Beam Flange Plate Moment Connection: Column/Beam Direct Weld Moment Connection: Flange Plate Options: When the beam frames into the column web, the flange plates now act as stiffeners to the vertical shear plate. These flange plates may be defined as Full Width, Tapered, or Coped in the Components input section. These new features are fully integrated and compatible with models exported from RISA-3D and RISAFloor…

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…
