The weld stresses between surfaces can be determined using the Stress-Strain Analysis add-on in RFEM 6. Furthermore, the stress limit determined according to the applicable standard can be input to determine the stress ratio of the weld. This article focuses on the fillet weld design according to AISC 360-22 [1] with two examples from AISC Volume 1: Design Examples [2].
This article demonstrates how to initiate and conduct the analysis in the software, followed by a short discussion of the underlying concept.
According to AISC Design Guide 9 Section 4.1 [1], the following torsional stresses must be considered for open cross-sections subjected to warping:
The Steel Joints add-on for RFEM 6 has taken a significant step forward by introducing semi-rigid hinges, a feature that dramatically enhances how steel connections are modeled in structural analysis. This new capability enables engineers to go beyond the traditional rigid or hinged connection assumptions, offering a more accurate and flexible way to represent the behavior of joints. With the ability to simulate joint stiffness through advanced initial stiffness analysis, the design process becomes more realistic and optimized, paving the way for safer and more cost-effective projects.
Want to automatically consider steel joint stiffness in your global RFEM model? Utilize the Steel Joints add-on!
Activate joint-structure interaction in the stiffness analysis of your steel joints. Hinges with springs are then automatically generated in the global model and included in subsequent calculations.
In the ultimate configuration of the steel joint design, you have the option to modify the limit plastic strain for welds.
The "Base Plate" component allows you to design base plate connections with cast-in anchors. In this case, plates, welds, anchorages, and steel-concrete interaction are analyzed.
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
