Seismic brace connections are a bit different from other connection types in RISAConnection. This is because the brace and connection elements must be designed for both tension and compression loading.
It is possible for seismic (OCBF or SCBF) vertical braced connections to have some limit state code checks lower than those for the same non-seismic connection.
Vertical Diagonal Brace connections and Vertical Chevron Brace connections may be designed as Special Concentric Braced Frame (SCBF) connections in RISAConnection v6.
This webinar shows users how to design and detail brace connections including gussets to meet the AISC 341/358 Seismic Provisions.
Vertical Diagonal Brace connections and Vertical Chevron Brace connections may be designed as Ordinary Concentric Braced Frame (OCBF) connections in RISAConnection v6.
RISAConnection v6 has introduced the ability to design vertical brace connections per the seismic design provisions of the AISC 341-10 Seismic Design Manual.
Wall Panel Forces Spreadsheet The power of RISA is the easy to access output. The Wall Panels have all the calculations and forces displayed in the Detail Report and now the new Wall Panel Forces gives you a quick way to get all the forces across the base of the wall. This new spreadsheet can be...
You may find that when looking at the Code Check spreadsheet that a given member is failing in design. Here is an example where a steel brace is failing in bending.
The Pacific Earthquake Engineering Research center (PEER) has a large library of measured earthquake records. Below is an example of how to quickly convert one of these records into a format that can be imported into RISA.
