How to View Wood Design Values
We have recently added a new View Design Properties dialog to allow you to now have the ability to easily view the wood design values prior to solution.
In structural steel projects, the transition from design to fabrication is a common source of coordination challenges. One of the biggest pain points? Connection design. Whether it’s miscommunication on end reactions or unclear design intent, connection assumptions can break down in the gap between engineering and detailing. By using RISA-3D and RISAConnection—and leveraging direct integrations with SDS2 and Tekla Structures—structural engineers can streamline the handoff to fabricators, reduce errors, and improve collaboration. This post walks through how to support real-world coordination using these tools in practice. 1. Model and Analyze the Steel Frame in RISA-3D Start by building your structural steel frame in RISA-3D. Define geometry, assign member sizes, apply loads, and analyze the model. Once you're satisfied with the analysis results, RISA-3D provides the connection forces—axial, shear, and moment reactions—for each member end. 2. Export Connection Forces to RISAConnection Next, send selected members and their design forces to RISAConnection. This direct integration eliminates the need to manually transfer loads or recreate geometry. Once in RISAConnection, you can: Choose from a library of shear, moment, and braced connections Model the full geometry, including bolt patterns, welds, and gusset plates View pass/fail results for each limit state, with clear failure mode…

In RISAFloor, there are several different Load Categories that define Live Load. The IBC and the ASCE7 both have provisions that allow you to reduce the tributary area of the Live Loads. These codes have equations that adjust the Live load based on the tributary area and usage (KLL*AT). In...
You can now customize the member and nodes names Revit uses during the export to RISA. When you export your Autodesk Revit model to RISA, the member and joint names are automatically altered with “REV” listed in front. This can helpful for you to identify that the model was created in Revit,...
Below is a model of a flat concrete slab made of plates. In order to ensure adequate serviceability of the slab, you may need to check the deflection of the slab between columns. However, RISA-3D only reports Member and Joint Deflections. There is no such thing as a “Plate Deflection”.
RISAFoundation has the ability to export detailed reinforcement drawings for footings, pile caps, pedestals, and slabs.
The Internal Force Summation Tool has the ability to "cut through" elements in the model and produce a summation of forces that corresponds with a given load combination. For this example, we will use the following model and review the summation of forces in the horizontal concrete plates.
The Load Combinations spreadsheet in RISA-3D is limited to ten columns of BLC and Factor combinations. However, there are times where you may need to include additional entries to your Load Combination. To do this, you can simply “nest” your load combinations.
After solution in RISA-3D, you can use Results View Settings to view the Plate Contours graphically on your model.
RISA has now incorporated the tapered member design provisions from Steel Design Guide 25: Frame Design Using Web-Tapered Members written by Richard Kaehler, Don White and Yoon Kuk Kim. These code checking procedures are used whenever the AISC 13th or 14th edition steel codes are selected.
