SCBF Seismic Brace Connections
Vertical Diagonal Brace connections and Vertical Chevron Brace connections may be designed as Special Concentric Braced Frame (SCBF) connections in RISAConnection v6.
Case Study: Designing for Strength at Every Level When a Midwest engineering firm was tasked with designing a 120,000-square-foot manufacturing facility, they knew the challenge wasn’t just about steel and concrete—it was about integration. The structure needed to support overhead cranes, custom conveyor systems, rooftop equipment, and a range of vibration-sensitive machinery. On top of that, the site’s soil profile required deep foundations and a mat slab in high-load zones. Instead of managing this complex design puzzle across multiple platforms, the firm turned to the full RISA Suite—using RISA-3D, RISAFloor, and RISAFoundation in tandem. The result? A seamless, accurate, and time-saving design process that allowed the firm to deliver ahead of schedule. Steel Superstructures Made Simple With RISA-3D, the team quickly modeled the facility’s steel framing system, including built-up columns, multi-bay trusses, and lateral bracing. Loads from the cranes, roof units, and custom mezzanines were easily applied using RISA’s versatile load generator and load combination tools. Key wins: Modeled the entire lateral and gravity system in a single file Ran multiple load scenarios including seismic, crane surge, and equipment-induced vibration Used RISA’s code checks to validate steel member sizing under heavy, variable loads Floor System Integration with RISAFloor With steel…

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...
Design for seismic connection detailing is now available in RISAConnection and you can use the connection rules within RISAFloor and RISA-3D to export a RISAConnection model. The integration will import the connection forces (and seismic detailing results) into RISAConnection for seismic moment...
