Hot-rolled haunched portal frames

Just because hot-rolled haunched portal frames are perhaps the most commonly used structure type in steel halls doesn’t mean designing portal frames is always straightforward for engineers. The moment resistant frame corner presents a challenge in both analysis and design.

No credit card required

Consteel equips you with the necessary tools to extend your knowledge of these seemingly routine tasks and enhance your designs accordingly.

With each project serving as an opportunity to gain insights into your structure’s true behavior. Our platform not only facilitates continuous learning and improvement but also allows you to rediscover the beauty of structural engineering.

True analysis of global steel structures – the 7 DOF beam element

Consteel is the only structural design software that uses the special 7 degrees-of-freedom (7 DOF) beam element for all the global structural analysis types. The 7 DOF element is specially developed for thin-walled members where the warping of the cross-section is of high importance in the behavior. Modeling is always done in 3D and various number of analysis types including special and unique ones (like global buckling, buckling sensitivity or imperfection analysis) are developed to assist you to get to know the true behavior of your structure and design it optimally.

Exact analysis of continuous frame corner regions

Corner zones have usually significantly different behavior than the connected beam members. Since these zones are very short, the behavior is influenced dominantly by the shear effect. Frame corner regions are semi-automatically recognised in Consteel and specific methods are applied to them during analyis and design with the consideration of kinematic constraint elements between the 7. DOF displacements of the neighbouring members (warping transfer) according to the chosen frame corner topology.

Immersive visualization of the true structural behavior

The key uniqueness of Consteel lies in its ability to model real structural behavior as accurately as possible, building automation and unique design procedures upon this foundation.
A crucial element of this approach is the immersive visualization, which enables a realistic representation of the deformations associated with the actual structural behavior—whether they result from applied loads or buckling shapes.
This visualization goes beyond conventional displacement components by also incorporating warping and other local deformations of structural elements, making the representation smoother and more realistic. It almost depicts the structure as if the beams and plates were analyzed using shell models.
Why is this important?
Because a visually striking and intuitive representation conveys the structural behavior far more effectively than even multiple pages of calculations or tables.

Automatic buckling design based on the ‘General Method’

General Method is the smartest way of stability design, described in EN 1993-1-1. It is applicable for any complex cases of out-of-plane buckling problems (flexural, torsional, and lateral-torsional buckling, and any interactions of these) with arbitrary members, loading and support conditions. Based on the global buckling and sensitivity analysis, it provides a comprehensive and automatic solution for stability design.
