Why Do Seismic Brace Story Forces Change My Existing Code Checks?
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.
As the fall leaves turn golden and Thanksgiving approaches, it's the perfect time to reflect on the advancements that have shaped the structural engineering industry. While we're all looking forward to turkey, stuffing, and time spent with family, we can't help but express our gratitude for the engineering innovations that make our work easier, faster, and more precise. Here’s a harvest of structural engineering innovations we’re especially thankful for, and how RISA has been a leader and supporter of these innovations. 1. The Power of Automation Just as Thanksgiving dinner wouldn’t be the same without a perfectly roasted turkey, structural engineering wouldn't be as efficient without automation. Gone are the days of tedious hand calculations and endless drafting. Tools like RISA-3D have automated complex analyses, from lateral systems to load combinations, saving time and improving accuracy. The ability to instantly generate designs and analyze models lets us focus on what really matters—ensuring the safety and integrity of our structures. Something to be thankful for: Less time crunching numbers means more time for pumpkin pie! 2. BIM Integration: The Recipe for Collaboration Much like Thanksgiving dinner, where every dish needs to complement the next, structural engineering is all about collaboration. Building…

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.
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.
Time history analysis solves for normal analysis results (joint displacements, member forces, code checks, etc.) based on loading that varies with time. For some analyses it may be useful to view an animation of the deflected shape of the structure as a function of time. This blog topic serves as a...
In the Seismic Loads dialog there is a checkbox for “Include structure weight in base shear”.
RIAFloor designs the gravity system and then integrates with RISA-3D to design the lateral system. Only the lateral members are taken from RISAFloor over to RISA-3D. The loading is automated in this integration so one of the most common questions is: what loads are transferred when switching from...
