Composite Steel Beam Design in RISACalc
Composite steel beam design is now available in RISACalc per the AISC and CSA steel design manuals with the following supported steel codes:
When modeling plate elements alongside member elements in RISA, users may notice that member forces—such as bending moments or axial loads—are lower than expected. This behavior is often the result of how loads are shared between plates and members based on their relative stiffness. If the distribution of forces doesn't align with your design expectations, it may be due to unintended interaction between these elements. Accurately capturing structural behavior requires not only the right modeling approach, but also a clear understanding of how plates and members interact within the analysis. In this article, we’ll explore common scenarios where this issue can arise, explain why it happens, and provide practical tips and workarounds to ensure your results match your design intent. Why Model Plate Elements in the First Place? Before diving into the interaction between elements, it’s worth asking: Do I need to model plate elements at all? In many cases, member design and stability can be accurately represented using simplified area or line loads—and plates might not be necessary. However, there are valid reasons to model plates, including: The model is unstable and needs plate elements for diaphragm action. Plates are part of the lateral load path. You want a…

Watch the recording of our webinar to learn how new versions of RISA-3D, RISAFloor, RISAFoundation and RISAConnection provide users with expanded design capabilities, improved product integration and new features including:
Open web steel joist design is now available in RISACalc per the SJI 43rd/44th and 42nd Editions! The available joist series include K-Series, LH-Series, DLH-Series, SLH-Series (42nd Edition only), and KCS joists.
The latest release of ADAPT-Builder 2019 includes improvements that include new tools for meshing, tendon force input and releasing the edges of shells.
The new RISACalc allows users to analyze single members (beams and columns) of all materials: hot rolled steel, wood, concrete, cold formed steel, aluminum, and stainless steel. The intuitive interface makes it easy to set up your model, apply loads, and view results.
