V minulosti byli statici při modelování spojů často omezeni na dvě možnosti: rigid or fully hinged. These simplified assumptions rarely reflect the actual behavior of steel connections, which tend to exhibit partial flexibility. With the introduction of semi-rigid hinges, RFEM 6 now offers a third, more nuanced option. By simulating the real-world stiffness of joints, this new feature allows for a more accurate analysis of how forces and stresses are distributed throughout a structure, leading to more precise and reliable design outcomes.
How it Works: Semi-Rigid Hinges in RFEM 6
The semi-rigid hinges feature works by integrating hinges into the global model before internal force calculations, based on an initial stiffness analysis. The process begins with the Steel Joints add-on automatically generating these semi-rigid connections, reflecting the real stiffness conditions of the joints. This feature removes the need for manual, time-consuming stiffness input and instead allows users to focus on the overall design of their structures, knowing that the connection behavior is accurately captured.
The simulation of semi-rigid hinges goes far beyond the traditional approaches to joint modeling. By accurately accounting for the partial stiffness of steel connections, this feature gives engineers a more realistic insight into how their structures will behave under various loads. This results in a more efficient and precise design, allowing engineers to anticipate potential issues and optimize the use of materials.

Why Semi-Rigid Hinges Matter for Your Projects
The inclusion of semi-rigid hinges in RFEM 6 offers several key advantages for structural engineering projects. First and foremost, it provides more accurate modeling of steel connections. In many projects, the behavior of connections plays a critical role in how loads are transferred and how the structure reacts under stress. By incorporating partial flexibility into joint models, engineers can achieve a better understanding of the force distribution throughout the structure, ensuring that all elements are designed to handle the actual loads they will face.
This level of accuracy is particularly critical in complex or large-scale projects where joint behavior can directly affect the structure's safety and performance. In many simplified designs, joints are often assumed to be fully hinged, overlooking the semi-rigid nature of real-world connections. This oversight can lead to unexpected moment forces, which, if not properly accounted for, may result in structural issues or even failure. By using semi-rigid hinges, engineers can accurately simulate these moments, significantly improving safety by preventing dangerous underestimations of joint behavior. This advanced modeling reduces the need for overly conservative designs and unnecessary material use, allowing engineers to make more informed decisions and create cost-effective solutions without compromising safety.
Another key advantage of semi-rigid hinges in RFEM 6 is its ability to calculate the initial stiffness of multiple connections throughout the entire structure, not just one joint. While other software often focuses on individual connections or basic static schemes, RFEM 6 analyzes how semi-rigid, fully rigid, or hinged connections impact the whole model. This comprehensive approach allows for better optimization of material use, load distribution, and safety standards, giving engineers a powerful tool for fine-tuning their designs with greater accuracy.
Major Step Forward in Structural Design
The integration of semi-rigid hinges into RFEM 6 is more than just a new feature—it represents a shift in how engineers can approach the modeling of steel structures. By providing a more detailed and realistic view of joint behavior, the semi-rigid hinges feature helps engineers create designs that are not only more accurate but also more efficient and cost-effective.
This development is especially important in today’s engineering landscape, where there is increasing pressure to optimize resources while maintaining high standards of safety and performance. The ability to simulate semi-rigid hinges means that engineers can avoid over-engineering their designs and instead focus on creating smarter, more streamlined solutions.
