Using Analysis Offsets in RISA-3D
Have you ever wondered what the Analysis Offset feature does? Let’s take a look at how this feature can be used to model members at top of steel.
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.

Have you ever wondered what the Analysis Offset feature does? Let’s take a look at how this feature can be used to model members at top of steel.
The new AISC 360-16 15th Edition changes have been implemented into RISA-3D v17.0 and RISAFloor v13.0.
“Why am I receiving a P-Delta instability error when I run my DL + LL load combination? I don’t see this error when I run my lateral load only combination.”
One of the support questions we get most often is, “How can I model a cable element in RISA-3D?” Cables that are straight and experience only axial loading can be easily modeled. When modeling structures with cables (such as guyed structures) the cables can be modeled as tension only and doing so...
For concrete column members, the load combination producing the maximum shear code check is reported in the Detail Report and corresponding Results spreadsheet. Since concrete is evaluated based on a batch solution, this can be useful when shear governs the design.
RISA-3D includes material specific checkboxes on the Design tab of the Load Combinations spreadsheet that allow you to define the load combinations that shall be checked for members of different materials.
RISA-3D now includes plate elements in the Material Takeoff.
There are many different types deflection values calculated by RISA-3D. Let’s take a deeper dive into each.
RISA-3D v16.0.4 introduces an enhancement that will allow for more control over the beam deflection ratio through Deflection Ratio Options. As part of the member properties, you can now designate the ends of single and multi-span beams as a cantilever or supported. This will determine whether the...
