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.
The winter months bring a unique set of challenges to structural engineering: projects slow down, site conditions become less predictable, and downtime can be harder to avoid. However, this season also brings opportunities to work smarter, streamline workflows, and plan ahead for a productive year. Here’s how you can help keep projects on track even in the frostiest months. 1. Winter Prep: Tackle Delayed Analysis Cold weather is often the perfect time to tackle those time-intensive analyses that may have been put on the back burner. With RISA-3D’s robust modeling environment, winter downtime becomes the ideal chance to dive into in-depth analysis and design. RISA-3D lets you quickly model complex geometries and visualize load paths in ways that manual calculations simply can’t replicate. And for foundation design, RISAFoundation can handle everything from frost heave assessments to wind uplift forces, enabling you to get the clearest picture of how your structures will withstand winter’s impact. Take advantage of the winter slowdown to refine and validate your foundation designs, ensuring every project element is prepared to endure the season. 2.

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.
RISAFloor ES allows you to model concrete slabs of any thickness. However, there might be sections of the building that require a thicker slab. The icon is shown below and it will allow you to draw a Polygon or Rectangular shape.
Ramp Up Function RISA allows you to define “Ramp Up Functions” to control how the force and frequency vary during this initial startup time. Typically cyclic equipment loading is applied as a reduced force or frequency when it is initially starting up. It would be overly conservative if it were...
